On 1 July 2026, the Ministry of Transport announced it was postponing full enforcement<\/strong> of the Speed Limitation Device requirement for commercial vehicles. That was the day Phase 3 \u2014 retrofit installation \u2014 had been scheduled to bite.<\/p>\n

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.<\/p>\n

Here is what actually changed, what did not, and what a sensible operator does with the extra time.<\/p>\n

The short version<\/h2>\n

Phase 3 enforcement is deferred. The obligation to fit an SLD is not.<\/strong><\/p>\n

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<\/em> is not suspension of the rule<\/em>.<\/p>\n

And JPJ is not going quiet during the gap. It will keep monitoring and taking interim action, including issuing Notices of Inquiry (114)<\/strong> to owners and operators found non-compliant. So a vehicle without a verified SLD is still exposed \u2014 it is just exposed to a notice rather than to full enforcement action.<\/p>\n

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.<\/p>\n

Why the ministry moved<\/h2>\n

The reason given was operational, not political. MOT said the decision followed feedback from industry \u2014 particularly large-fleet operators still in the middle of scheduling retrofit installations.<\/p>\n

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.<\/p>\n

As of mid-2026 there were 25 companies appointed to carry out SLD retrofit installations<\/strong>, with details published on the JPJ portal. That capacity number is the real constraint, and it is why the timeline slipped.<\/p>\n

Where the three phases actually stand<\/h2>\n

The phased structure is unchanged. Only Phase 3’s enforcement date has moved.<\/p>\n

\n\n\n\n\n\n\n\n
Phase<\/th>\nApplies to<\/th>\nRequirement<\/th>\nStatus<\/th>\n<\/tr>\n<\/thead>\n
Phase 1<\/strong><\/td>\nCommercial vehicles manufactured on or after 1 January 2015<\/strong><\/td>\nVerification of SLD functionality<\/td>\nIn force since 1 October 2025<\/strong><\/td>\n<\/tr>\n
Phase 2<\/strong><\/td>\nCommercial vehicles manufactured before 1 January 2015<\/strong><\/td>\nActivation of the SLD in the Electronic Control Unit<\/td>\nIn force since 1 January 2026<\/strong><\/td>\n<\/tr>\n
Phase 3<\/strong><\/td>\nCommercial vehicles not already equipped<\/strong> with an SLD<\/td>\nRetrofit installation, subject to JPJ verification<\/td>\nOriginally 1 July 2026 \u2014 full enforcement now deferred<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Two things people get wrong about this table.<\/p>\n

First, Phases 1 and 2 are still live.<\/strong> 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 \u2014 you are simply late on Phase 1.<\/p>\n

Second, the split is by build date and ECU capability, not by how old the vehicle feels.<\/strong> 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.<\/p>\n

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<\/a> explains why that distinction is not cosmetic.<\/p>\n

What the rule still requires<\/h2>\n

None of this changed on 1 July.<\/p>\n
