On 1 July 2026, the Ministry of Transport announced it was postponing full enforcement of the Speed Limitation Device requirement for commercial vehicles. That was the day Phase 3 — retrofit installation — had been scheduled to bite.
If you run a fleet and you have been treating 1 July as your hard wall, the wall moved. But it did not disappear, and the way JPJ has framed the deferment matters more than the fact of it.
Here is what actually changed, what did not, and what a sensible operator does with the extra time.
The short version
Phase 3 enforcement is deferred. The obligation to fit an SLD is not.
The ministry was explicit on this point. Its statement said that all operating companies, commercial vehicle owners, logistics operators, bus operators and related parties must continue taking immediate steps to fit SLDs in line with the prescribed requirements and technical specifications. Deferment of enforcement is not suspension of the rule.
And JPJ is not going quiet during the gap. It will keep monitoring and taking interim action, including issuing Notices of Inquiry (114) to owners and operators found non-compliant. So a vehicle without a verified SLD is still exposed — it is just exposed to a notice rather than to full enforcement action.
No replacement deadline has been published. The ministry’s phrasing was that once the grace period ends, enforcement action will be taken against any company, owner or operator that has not complied. That is a deliberately open door, and it is not a safe thing to plan around.
Why the ministry moved
The reason given was operational, not political. MOT said the decision followed feedback from industry — particularly large-fleet operators still in the middle of scheduling retrofit installations.
The ministry acknowledged what anyone who has actually run a retrofit programme already knows: it needs technical planning, vehicle scheduling, functionality verification and operational coordination, and doing it badly disrupts services and the national logistics supply chain. Pulling twenty lorries off the road in the same week to sit in a workshop queue is not a compliance strategy. It is a revenue event.
As of mid-2026 there were 25 companies appointed to carry out SLD retrofit installations, with details published on the JPJ portal. That capacity number is the real constraint, and it is why the timeline slipped.
Where the three phases actually stand
The phased structure is unchanged. Only Phase 3’s enforcement date has moved.
| Phase | Applies to | Requirement | Status |
|---|---|---|---|
| Phase 1 | Commercial vehicles manufactured on or after 1 January 2015 | Verification of SLD functionality | In force since 1 October 2025 |
| Phase 2 | Commercial vehicles manufactured before 1 January 2015 | Activation of the SLD in the Electronic Control Unit | In force since 1 January 2026 |
| Phase 3 | Commercial vehicles not already equipped with an SLD | Retrofit installation, subject to JPJ verification | Originally 1 July 2026 — full enforcement now deferred |
Two things people get wrong about this table.
First, Phases 1 and 2 are still live. The deferment applies to full enforcement of the retrofit phase. If your 2018 lorry has never had its SLD functionality verified, you are not sheltering under the deferment — you are simply late on Phase 1.
Second, the split is by build date and ECU capability, not by how old the vehicle feels. A pre-2015 vehicle with an SLD-capable ECU is a Phase 2 activation job. A pre-2015 vehicle without one is a Phase 3 retrofit.
If you have never run the diagnostic, you do not actually know which pile a vehicle is in. Our breakdown of ECU-based versus GPS-based speed limiters explains why that distinction is not cosmetic.
What the rule still requires
None of this changed on 1 July.
- Scope. JPJ’s SLD guideline covers goods vehicles with BDM above 3,500 kg, and passenger vehicles with BDM above 5,000 kg carrying more than eight passengers.
- Speed setting. The device caps the vehicle at 90 km/h. It cuts throttle and fuel; it does not apply the brakes.
- Documentation. Two documents, both of which JPJ officers and PUSPAKOM ask for: the Slip Pengesahan Kefungsian SLD (functional verification slip) and the Laporan Kefungsian SLD (functional report).
- Validity. Verification is reported to be valid for two years, after which the device must be re-verified.
- Who signs it. For an OEM-installed SLD, the slip should come from the OEM. For a retrofit, it must come from a JPJ-recognised verifier. JPJ publishes the list of recognised verification bodies on its portal.
That last point is where most of the avoidable pain sits. A device that works but was signed off by a workshop not on JPJ’s list is, for inspection purposes, a device that does not exist.

There is money on the table, and it expires before the grace period is over
This is the part being under-reported.
Under Budget 2026, the government introduced an Accelerated Capital Allowance facility to help companies with the cost of installing SLDs. The ministry confirmed it is available until 31 December 2026.
Read those two dates together. The enforcement deadline is now open-ended. The financial assistance is not. An operator who waits for a new deadline to be announced may well end up retrofitting after the allowance window has closed — paying full freight for work they could have expensed.
The deferment did not make the retrofit cheaper. It made it easier to miss the point at which it was cheapest.
What to actually do with the extra time
Not “book early to beat the rush.” That advice was written for a deadline that no longer exists. Do this instead:
1. Close out Phases 1 and 2 first. These are enforceable today. Pull your fleet list, sort by manufacture date against 1 January 2015, and confirm every vehicle on the newer side has a valid verification slip. This is the cheapest compliance you will ever buy — it is mostly paperwork on devices you already own.
2. Run the ECU diagnostic on the pre-2015 vehicles. You are trying to answer one question per vehicle: does the ECU support SLD activation, or does it need a retrofit? Guessing this wrong is what turns a two-hour activation into a workshop day.
3. Schedule retrofits against the allowance, not the deadline. Work backwards from 31 December 2026, not from a phantom enforcement date. Front-load the vehicles that will cost the most to retrofit.
4. Fix your document trail. Verification is valid two years. If your Phase 1 vehicles were verified in October 2025, they come up for re-verification in October 2027 — and that will land in the same window as your Phase 3 retrofits.
Put both on the same calendar now. Our note on installing and calibrating speed governors in Malaysia covers what the verifier will actually check.
5. Do not treat the deferment as a signal. JPJ is still issuing Notices of Inquiry. The ministry’s own language — “must continue to take immediate steps” — is not the language of a regulator that has gone soft.

Frequently asked questions
Has the SLD requirement been cancelled?
No. Full enforcement of Phase 3 has been postponed. The requirement to fit and verify a Speed Limitation Device remains in force, and MOT has said operators must continue taking immediate steps to comply.
Is there a new Phase 3 deadline?
Not as of mid-July 2026. The ministry has said enforcement action will follow once the grace period ends, without naming a date. Check the JPJ portal rather than relying on any published figure, including this one.
Do Phases 1 and 2 still apply?
Yes — they are in force now. Phase 1 has been enforceable since 1 October 2025 and Phase 2 since 1 January 2026. The deferment does not reach back and cover them.
Can JPJ still act against me during the deferment?
Yes. JPJ has said it will continue monitoring and taking interim action, including issuing Notices of Inquiry (114) to non-compliant owners and operators.
What speed do SLDs limit to in Malaysia? 90 km/h.
The device restricts throttle and fuel delivery once the vehicle reaches the threshold. It does not apply braking force. Drivers still have to obey lower posted limits.
How long is SLD verification valid?
Verification is reported to be valid for two years, after which the vehicle must be re-verified. Keep both the verification slip and the functional report in the vehicle.
