JPJ speed limiter fitting for Penang fleets on both sides of the bridges
Fit a sealed, JPJ-compliant Speed Limitation Device on every Penang lorry that crosses the channel. Haulers from Butterworth and Prai reach the island over the 13.5 km Penang Bridge or the 24 km Sultan Abdul Halim Muadzam Shah Bridge, and Penang Port moved 32.33 million tonnes of cargo in 2024. Phase 1 and Phase 2 enforcement is active now.
Verified against the Motor Vehicles (SLD) Rules 2002, UN R89 aligned. Enforcement updates from BERNAMA, Penang Port 2024 figures, and Puspakom-ready paperwork.

Penang freight
Why a Penang fleet runs on a different compliance map
Penang freight works on two sides of the water. Port traffic and heavy industry sit on the Seberang Perai mainland around Butterworth, Prai and Batu Kawan, while the electronics campuses of the Bayan Lepas Free Industrial Zone sit on the island.
Every heavy vehicle that links the two, and every lorry heading north to Kedah or south to Perak on the North-South Expressway, falls inside JPJ SLD enforcement.
Port capacity may also grow: a proposed RM2.2 billion expansion of the North Butterworth Container Terminal was still awaiting government approval in September 2024. If it goes ahead, more containers through Butterworth will mean more haulage across the bridges.

Two crossings
Two bridges, one JPJ rule for Penang lorries
Most cross-channel haulage uses one of two road bridges. Both are public roads, so the JPJ SLD rules apply on both, whichever route your dispatcher picks.
The Penang Bridge between Seberang Perai and Gelugor.
| Penang Bridge | Sultan Abdul Halim Muadzam Shah Bridge | |
|---|---|---|
| Opened | 14 September 1985 | 1 March 2014 |
| Length | 13.5 km | 24 km |
| Mainland end | Seberang Perai (Perai) | Batu Kawan |
| Island end | Gelugor | Batu Maung |
| Freight nearby | Butterworth port, Prai industrial area | Batu Kawan industrial park, Bayan Lepas FIZ |
One Electronic Speed Limiter set to 90 km/h covers either bridge. If the same lorry also works port yards or estate roads with their own site limits, a Multi-Speed Limiter can hold a separate GPS-geofenced profile for those zones.

Why fleets move now
What Penang fleet managers tell us once the audit is done
A lorry that only shuttles between Batu Kawan and Bayan Lepas is still a goods vehicle over 3,500 kg on a public road. The SLD rule follows the vehicle, not the length of the trip.
Check which lorries need a device →We fit prime movers at your Butterworth or Prai yard between shifts, seal the device at 90 km/h and hand over the paperwork before the lorry goes back into rotation.
Book a port-yard fitting →Phase 1 and Phase 2 are live. JPJ can still issue a Notis Siasatan under Section 114 for a missing or non-working SLD while the Phase 3 retrofit date is pending.
Ask for a fleet audit →The SLD Functionality Verification Certificate and Laporan Kefungsian SLD are prepared at fitting, so the inspection slot is spent verifying, not filling in forms.
Ask about the paperwork pack →Resolute Dynamics builds the devices it fits, so a lorry based in Prai and one based in Bayan Lepas run the same configuration and renew on the same terms.

The devices we fit for Penang fleets
Built by Resolute Dynamics, set to 90 km/h and sealed at fitting, with the verification paperwork ready.
Electronic Speed Limiter
Our standard fit for Butterworth and Prai container haulers crossing to the island. Caps the throttle signal and seals at 90 km/h.
Cross-channel haulage
Fuel Type Speed Limiter
Caps fuel delivery instead of the throttle signal, which suits older diesel lorries in the Bukit Mertajam and Juru distribution belt.
Older diesel lorries
Dual & Multi-Speed Limiter
Two to four GPS-geofenced profiles, for lorries that mix port yards, estate roads and public roads in a single shift.
Mixed-zone work
RPM Regulator
Caps engine revolutions to reduce driveline wear on high-mileage lorries running the North-South Expressway to Kedah and Perak.
High mileageWhy Penang operators should not wait for the Phase 3 date
The Ministry of Transport postponed the Phase 3 retrofit deadline of 1 July 2026, but Phase 1 and Phase 2 are enforced today. JPJ checks SLD function on goods vehicles over 3,500 kg and passenger vehicles over 5,000 kg carrying more than 8 people, and issues a Notis Siasatan under Section 114 when a device is missing or not working. Fleets that fit now are not competing for inspection slots when a new Phase 3 date is announced.
FAQ
Penang SLD questions
Which Puspakom branches verify SLDs in Penang?
Commercial vehicles in Penang are inspected at Puspakom Butterworth (Prai) on the mainland and Puspakom Bayan Lepas on the island. We prepare the SLD paperwork at fitting so either branch can verify it.
Does a lorry that only runs between Batu Kawan and Bayan Lepas need an SLD?
Yes. The rule applies to goods vehicles over 3,500 kg GVW on public roads, whatever the trip length, and both bridges are public roads.
Does the speed limiter slow lorries down on the bridges?
No. The device only stops the vehicle going above 90 km/h. Below that it has no effect on acceleration or normal driving.
Are Penang Port container haulers covered?
Yes. Prime movers and container haulers serving Penang Port and the North Butterworth Container Terminal are goods vehicles over 3,500 kg, so they fall inside the JPJ SLD rules.
Can you fit on the mainland and on the island?
Yes. We fit at depots in Butterworth, Prai, Bukit Mertajam and Batu Kawan, and on the island in Bayan Lepas, Bayan Baru and George Town.
When does enforcement apply to existing Penang vehicles?
Post-2015 vehicles came under enforcement on 1 October 2025 and pre-2015 vehicles on 1 January 2026. The Phase 3 retrofit date of 1 July 2026 is the only one postponed, so a Penang lorry without a working SLD can still receive a Notis Siasatan today.
