The Road Transport Department, known locally as Jabatan Pengangkutan Jalan (JPJ), now requires these vehicles to carry a <strong>Speed Limitation Device (SLD)<\/strong> that caps the engine at <strong>90 km\/h<\/strong>. That cap holds even on an expressway where the signboard says 110.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">The mandate sits under the Ministry of Transport (MOT), it covers goods vehicles above 3,500 kg and passenger vehicles above 5,000 kg, and it splits fleets by one date that matters more than any other: 1 January 2015.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">I have spent years watching transport regulations shift across this region, and few rules have landed with as much weight as this one.

JPJ enforces it, the Ministry of Transport authorised it, and the technical baseline mirrors <strong>United Nations Regulation No. 89 (UN R89)<\/strong>, the same homologation standard Europe leans on for speed limiters.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Here is the heart of it. A Speed Limitation Device is a small electronic governor that talks directly to your vehicle&#8217;s brain, the Electronic Control Unit (ECU). Once your bus or lorry touches the governed ceiling, the device steps in and refuses to let the engine push past it. No drama. No braking jolt. The driver can floor the pedal all day, and the coach still will not breach 90.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">A few facts worth pinning down:<\/p>\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\">\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Regulator:<\/strong> Jabatan Pengangkutan Jalan (JPJ), under the Ministry of Transport Malaysia (MOT)<\/li>\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Device required:<\/strong> Speed Limitation Device (SLD), permanently fitted and tamper-resistant<\/li>\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Speed ceiling:<\/strong> 90 km\/h, set inside the ECU or the SLD module<\/li>\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Legal anchor:<\/strong> national road safety directive aligned with UN Regulation No. 89<\/li>\n<\/ul>\n<p class=\"font-claude-response-body break-words whitespace-normal\">This is not a soft suggestion. It is a compliance requirement tied to your operating permit, your inspection result, and in stubborn cases, your licence to keep the wheels turning.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">Which Vehicles Must Comply With the SLD Rules?<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\">The rules apply to two broad families of heavy vehicles: passenger carriers above 5,000 kg and goods carriers above 3,500 kg. Vehicle engineers classify them under the <strong>M3, N2, and N3<\/strong> categories, the same shorthand used across UN vehicle standards.<\/p>\n<div class=\"overflow-x-auto w-full px-2 mb-6\">\n<table class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\">\n<thead class=\"text-left\">\n<tr>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Vehicle category<\/th>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">UN class<\/th>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Weight threshold<\/th>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Passenger threshold<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Express, tour &amp; cruise buses<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">M3<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">GVW above 5,000 kg<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">More than 8 passengers (excluding driver)<\/td>\n<\/tr>\n<tr>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Medium goods vehicles<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">N2<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">GVW above 3,500 kg<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Not applicable<\/td>\n<\/tr>\n<tr>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Heavy goods vehicles<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">N3<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">GVW above 3,500 kg<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Not applicable<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p class=\"font-claude-response-body break-words whitespace-normal\">There is one more filter sitting on top of weight and seating: the <strong>manufacture date<\/strong>. A vehicle built on or after 1 January 2015 follows a different path than one built before it. I will untangle that in the enforcement section, because it decides which deadline grips your fleet.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Express Buses and Tour Buses<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Express buses and tour buses are squarely inside the mandate. These are M3 vehicles built to seat more than eight passengers beyond the driver, with a gross vehicle weight above 5,000 kg.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Their high passenger load and long-haul routes are exactly why regulators want a hard velocity ceiling on them. A packed coach hurtling down the North\u2013South Expressway at 120 carries a far heavier consequence than a single car doing the same.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Heavy Goods Vehicles and Lorries<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Lorries and heavy goods vehicles fall under the N2 and N3 classes, triggered once the gross vehicle weight passes 3,500 kg. Prime movers, tippers, tankers, and container haulers all sit here. The logic is the same as with buses: more mass means longer stopping distance, and an uncapped throttle turns a small misjudgement into a large catastrophe.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Cruise Buses and Other High-Capacity Passenger Vehicles<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Cruise buses and other high-capacity passenger vehicles share the express-bus rulebook. JPJ has openly singled out this segment for lagging behind, and the numbers tell the story.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">As of mid-March 2026, nearly half of the country&#8217;s active cruise buses had still not completed their SLD verification, against a far healthier compliance rate among scheduled express buses. If you operate in this niche, you are under a brighter spotlight than most.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">What Is the Mandatory Speed Limit for Express Buses in Malaysia?<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\">The mandatory speed limit for express buses fitted with an SLD is <strong>90 km\/h<\/strong>, and the device enforces it no matter what the road sign permits. An expressway might allow 110 km\/h for ordinary cars, yet your governed coach will still flatten out at 90. The SLD does not negotiate.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">One nuance trips up a lot of operators, so let me be clear about it. The 90 km\/h ceiling is a maximum, not a target. Drivers must still obey every lower posted limit, including 60 km\/h school zones, town stretches, and roadwork corridors.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">The SLD only stops the high end. It does nothing about the human duty to slow down where the road demands it. Think of it as a hard lid on the top, while the everyday judgement still belongs to the person behind the wheel.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">Speed Limiter Enforcement Phases and Deadlines<\/h2>\n<p><img decoding=\"async\" class=\"wp-image-2786 aligncenter\" src=\"https:\/\/speed.resolute-dynamics.com\/blog\/wp-content\/uploads\/2026\/06\/Speed-Limiter-Enforcement-Phases-and-Deadlines.jpg\" alt=\"Speed Limiter Enforcement Phases and Deadlines\" width=\"710\" height=\"536\" \/><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">JPJ rolled out enforcement in stages so operators were not flattened by a single overnight deadline. The phasing hinges on two things: when your vehicle was built, and whether it already carries a working speed limiter.<\/p>\n<div class=\"overflow-x-auto w-full px-2 mb-6\">\n<table class=\"min-w-full border-collapse text-sm leading-[1.7] whitespace-normal\">\n<thead class=\"text-left\">\n<tr>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Phase<\/th>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Vehicle scope<\/th>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Action required<\/th>\n<th class=\"text-text-100 border-b-0.5 border-[hsl(var(--border-300)\/0.6)] py-2 pr-4 align-top font-bold\" scope=\"col\">Key date<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Phase 1<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Built on\/after 1 Jan 2015<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Verify SLD functionality<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">1 October 2025<\/td>\n<\/tr>\n<tr>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Phase 2<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Built before 1 Jan 2015 (with ECU limiter)<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Activate the in-built limiter<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">January 2026<\/td>\n<\/tr>\n<tr>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Phase 3<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Never fitted with an SLD<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">Retrofit an approved device<\/td>\n<td class=\"border-b-0.5 border-[hsl(var(--border-300)\/0.3)] py-2 pr-4 align-top\">1 July 2026<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Phase 1 \u2013 SLD Functionality Verification (1 October 2025)<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Phase 1 began on 1 October 2025 and targets newer vehicles, meaning those manufactured on or after 1 January 2015. These coaches and lorries usually already have speed-limiting capability baked into the ECU from the factory. The task here is verification, not installation. A recognised inspector confirms the limiter is active, correctly calibrated to 90 km\/h, and tamper-free, then issues the paperwork that proves it.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Phase 2 \u2013 ECU Activation for Pre-2015 Vehicles (January 2026)<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Phase 2 covers older vehicles built before 1 January 2015 that still have a dormant limiter inside the ECU. For this group, the requirement is activation. The factory function gets switched on, calibrated to the legal ceiling, and verified. No new hardware is bolted in if the ECU can already do the job. This phase carries its own enforcement timeline that began rolling in early 2026.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Phase 3 \u2013 Retrofit SLD Installation (1 July 2026)<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Phase 3 handles the toughest group: vehicles that were never fitted with any speed limiter at all. These need a full retrofit, where a JPJ-approved external SLD is wired into the engine management system and calibrated from scratch. Enforcement for this retrofit category lands on 1 July 2026, giving owners a runway to source, install, and certify before checks bite.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Rebuilt Vehicle Deadline Extension (1 July 2026)<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Rebuilt commercial vehicles received a breathing space. These are used trucks and buses imported from right-hand-drive markets such as the United Kingdom and Japan, then refurbished for Malaysian roads. Because sourcing compatible limiter software for so many variants proved messy, JPJ shifted their retrofit deadline from 1 January 2026 to <strong>1 July 2026<\/strong>. The extension softens the timeline, but it does not water down the underlying duty to fit a working device.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">SLD Verification and Documentation Requirements<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Compliance is not real until it is documented. Every verified vehicle must hold two specific records, written in Bahasa Malaysia on the official slips:<\/p>\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\">\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Slip Pengesahan Kefungsian SLD<\/strong> \u2014 the SLD Functionality Confirmation Slip<\/li>\n<li class=\"font-claude-response-body whitespace-normal break-words pl-2\"><strong>Laporan Kefungsian SLD<\/strong> \u2014 the detailed SLD Functionality Report<\/li>\n<\/ul>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Both documents must be renewed every <strong>two years<\/strong>, and both must stay inside the vehicle at all times for roadside checks. Lose the paper and you are non-compliant on the spot, even if the device itself is humming along perfectly. The audit trail matters as much as the hardware.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Who Can Issue SLD Verification<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Verification can only come from parties JPJ trusts. That short list includes JPJ-recognised <strong>Technical Services (TS) centres<\/strong>, certified workshops, accredited certification bodies, and the original vehicle manufacturers.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">A slip from anyone outside this circle carries no legal weight. This is also why picking your installer matters: a non-authorised provider can leave you with a device that works but paperwork that does not.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Where SLD Documents Are Checked<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Your SLD records surface at several checkpoints, not just one. They are inspected at <strong>Puspakom<\/strong> (the Motor Vehicle Inspection Centre, also referred to as PPKM), demanded during permit renewal with the Land Public Transport Agency (<strong>APAD<\/strong>) and the Commercial Vehicle Licensing Board (<strong>LPKP<\/strong>), and pulled up during routine JPJ roadside enforcement.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Verifiers also upload each slip and report to JPJ&#8217;s online system, so the data follows the vehicle digitally as well.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">Penalties for Non-Compliance With Malaysia&#8217;s Speed Limiter Rules<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Skipping the rules gets expensive, fast. Compound fines run from <strong>RM3,000 to RM10,000 per vehicle<\/strong>, and the pain rarely stops at the wallet. Repeat offenders risk operating-permit revocation, placement on a JPJ enforcement watchlist, court summons for stubborn cases, and an outright operational shutdown until the vehicle is brought into line.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">For a fleet, the math is brutal. A handful of non-compliant coaches can rack up tens of thousands in compounds before you have even lost a contract over a failed inspection. The cheaper road, by a wide margin, is to verify early and keep the documentation current.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">How a Speed Limitation Device Works<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\">A Speed Limitation Device works by reading your vehicle&#8217;s real speed and trimming the engine the instant you reach the governed ceiling. It plugs into the <strong>Electronic Control Unit (ECU)<\/strong> and listens to speed signals drawn from the ABS sensors, the CAN bus, or the transmission output.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">The moment the reading hits 90 km\/h, the device modulates throttle response and tapers the fuel supply so the engine simply cannot accelerate further.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">What it does not do is just as important. It never applies the brakes, so there is no lurching or sudden deceleration. Below the ceiling, the vehicle drives exactly as it always did, with no change to pulling power, climbing ability, or fuel economy in normal conditions.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Certified units are built tamper-resistant, and some models include an emergency <strong>kick-down override<\/strong> for the rare moment a burst of speed prevents a worse outcome. The whole system runs quietly in the background, doing its single job: holding the lid on top-end speed.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">If you want to dig into the hardware side, the device family that powers this includes the standard <a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/speed.resolute-dynamics.com\/speed-limiter-speed-governor.php\">Speed Limiter \/ Speed Governor<\/a> and the terrain-aware <a class=\"underline underline underline-offset-2 decoration-1 decoration-current\/40 hover:decoration-current focus:decoration-current\" href=\"https:\/\/speed.resolute-dynamics.com\/dual-speed-limiter-multi-speed-limiter.php\">Dual Speed Limiter and Multi Speed Limiter<\/a>, which lets you set different ceilings for different road zones.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">How Express Bus and Fleet Operators Can Comply<\/h2>\n<p><img decoding=\"async\" class=\"size-full wp-image-2787 aligncenter\" src=\"https:\/\/speed.resolute-dynamics.com\/blog\/wp-content\/uploads\/2026\/06\/How-Express-Bus-and-Fleet-Operators-Can-Comply.jpg\" alt=\"How Express Bus and Fleet Operators Can Comply\" width=\"576\" height=\"308\" srcset=\"https:\/\/speed.resolute-dynamics.com\/blog\/wp-content\/uploads\/2026\/06\/How-Express-Bus-and-Fleet-Operators-Can-Comply.jpg 576w, https:\/\/speed.resolute-dynamics.com\/blog\/wp-content\/uploads\/2026\/06\/How-Express-Bus-and-Fleet-Operators-Can-Comply-300x160.jpg 300w\" sizes=\"(max-width: 576px) 100vw, 576px\" \/><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Compliance is a sequence, and following it in order keeps you out of trouble.

A devastating bus crash near Gerik claimed the lives of 15 university students, with investigators estimating speeds around 117 km\/h, well beyond anything safe for a loaded coach on that road.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">Earlier disasters, including a notorious Genting Highlands bus crash, had already exposed how lethal an uncapped heavy vehicle becomes when speed and human error collide.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">This mandate is Malaysia&#8217;s structural answer to that pattern. It removes speed from a driver&#8217;s discretion at the hardware level, which is the whole point of the <strong>Vision Zero<\/strong> philosophy and the <strong>ASEAN Road Safety Strategy<\/strong> the country has signed onto.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\">The framework draws on research from the Malaysian Institute of Road Safety Research (<strong>MIROS<\/strong>) and technical standards from <strong>SIRIM<\/strong> and the international <strong>UN Regulation No. 89<\/strong>. In short, it aligns Malaysian heavy-vehicle safety with the same benchmarks already running in Singapore and across Europe.<\/p>\n<h2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\">Frequently Asked Questions<\/h2>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>Is a speed limiter mandatory for express buses in Malaysia?<\/strong> Yes. Express buses, tour buses, and cruise buses classified as M3 vehicles with a gross vehicle weight above 5,000 kg and seating for more than eight passengers must run a JPJ-approved Speed Limitation Device.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>What is the SLD speed limit in Malaysia?<\/strong> The SLD caps maximum speed at 90 km\/h, and it holds that ceiling regardless of the posted road limit. Drivers must still obey any lower posted limits.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>Do buses registered before 2015 need an SLD?<\/strong> Yes. Vehicles built before 1 January 2015 fall under Phase 2 or the retrofit phase. If the ECU already supports speed limiting, the function is activated; if not, an approved device is retrofitted.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>How often must SLD verification be renewed?<\/strong> Every two years. The renewed Functionality Report and Confirmation Slip must be presented during inspection and permit renewal, and kept in the vehicle between checks.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>What documents must be kept in the vehicle?<\/strong> Two records: the Slip Pengesahan Kefungsian SLD (Functionality Confirmation Slip) and the Laporan Kefungsian SLD (Functionality Report). Both must travel with the vehicle at all times.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>What is the penalty for operating without an SLD?<\/strong> Compound fines range from RM3,000 to RM10,000 per vehicle, with the risk of permit revocation, watchlisting, and operational shutdown for repeated non-compliance.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\"><strong>Who can install and verify a JPJ-approved SLD?<\/strong> Only JPJ-recognised Technical Services centres, certified workshops, accredited certification bodies, or original vehicle manufacturers can install, calibrate, and verify the device.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>If you run an express bus, a tour coach, or a fleet of lorries in
