JPJ speed limiter fitting for Ipoh quarry, cement and distribution lorries
Book an SLD fitting for your Ipoh lorries before their next Puspakom slot. Kinta Valley haulage runs short, heavy loops between limestone quarries around Simpang Pulai, the cement plant at Kanthan and the North-South Expressway, and every loaded lorry over 3,500 kg on a public road falls under the JPJ SLD rules.
Verified against the Motor Vehicles (SLD) Rules 2002, UN R89 aligned. Enforcement updates from BERNAMA, JPJ revised brake test, and Puspakom-ready paperwork.
The Kinta haul cycle
Quarry, public road, plant: three speed zones on every Ipoh haul
A Kinta Valley haul lorry passes through three speed regimes on each loop. Only one of them is governed by JPJ, but one device can hold all three.
Quarry and haul road
Inside the quarry the operator sets the speed rules. The JPJ SLD cap does not apply on private land.
Federal roads and PLUS
From the quarry gate to the plant or the North-South Expressway the lorry is on public roads, where the JPJ SLD rule and Notis Siasatan risk apply.
Plant yard and weighbridge
At the cement plant the site rules take over again for yard moves, loading and the weighbridge.
The hardware
Devices for Kinta Valley haulage
Built and fitted by Resolute Dynamics, sealed at 90 km/h for the public-road leg of every loop.
Dual & Multi-Speed Limiter
Built for mixed-site work like the Kinta quarry cycle. Two to four GPS-geofenced profiles let one device hold the quarry limit, the public-road cap and the plant limit on the same loop, with no driver input.
Quarry to plant
Electronic Speed Limiter
The straightforward fit for Ipoh distribution lorries that stay on public roads. Throttle-signal cap, sealed at 90 km/h.
Distribution
Fuel Type Speed Limiter
Fuel-delivery cap for older diesel tippers that do not suit a throttle-signal device.
Older tippers
RPM Regulator
Caps engine revolutions to reduce wear on lorries that run loaded, repeated short loops.
Heavy duty cycles

Ipoh in context
Why Ipoh fleets are under more scrutiny, not less
Regulators are watching the Kinta quarry belt closely. In September 2026 a quarry at Simpang Pulai was ordered to halt operations after a fatal rockfall. Site safety and road safety are separate rules, but operators are reviewing both, and a sealed, Puspakom-verified SLD on every haul lorry is the road-side part.
On the road side, JPJ's revised brake test, in force since 12 January 2026, fails lorries whose brakes are set excessively tight or loose. For quarry and cement lorries that brake hard and often, book the brake check and the SLD fitting in one workshop visit.

Where we fit
Kinta Valley areas we cover
We fit at depots, workshops and quarry-side yards across Ipoh and the Kinta Valley.
Commercial inspection for these areas is at Puspakom Ipoh. For the national rules, see the JPJ speed limiter guide for Malaysia.
Why fleets move now
Why Ipoh fleet managers book now instead of waiting
Only the Phase 3 retrofit date of 1 July 2026 was postponed. Post-2015 lorries have been checked since 1 October 2025 and older lorries since 1 January 2026, with Notis Siasatan under Section 114 for a missing or faulty device.
Ask for a fleet audit →A tipper that spends most of its day inside the quarry becomes a goods vehicle on a public road the moment it leaves the gate. If it is over 3,500 kg, it needs a working SLD for that leg.
Check your tipper fleet →Bulk tankers loaded at the plant run heavy on every trip. Book the SLD fitting alongside the brake check that JPJ's revised test now demands, and the lorry goes to Puspakom once.
Book a combined visit →We prepare the SLD Functionality Verification Certificate and Laporan Kefungsian SLD at fitting, so your slot at Puspakom Ipoh is spent on verification.
Ask about the paperwork pack →Resolute Dynamics makes the devices it installs, which keeps quarry, cement and distribution lorries on one configuration with one point of contact for renewals.

FAQ
Ipoh SLD questions
If the lorry is over 3,500 kg GVW and uses public roads at all, yes. Inside the quarry the operator's site rules apply, but the JPJ SLD rule applies the moment the lorry joins a public road.
Puspakom Ipoh handles commercial inspections for Ipoh and the Kinta Valley. We prepare the SLD paperwork at fitting so the slot is spent on verification.
Since 12 January 2026, lorries fail if brakes are set excessively tight or loose, with a drag-force check. Lorries that brake hard and often should have their brakes checked before the Puspakom visit; we suggest the same workshop visit as the SLD fitting.
Yes. A Dual and Multi-Speed Limiter holds two to four GPS-geofenced profiles, so it can apply a site limit in the quarry, the 90 km/h JPJ cap on public roads and another site limit at the plant.
From 1 October 2025 for vehicles registered after 1 January 2015, and from 1 January 2026 for older vehicles. The Phase 3 retrofit date was postponed; the first two phases were not.
