The Ministry of Transport (MOT) announced the deferral of the full enforcement of the mandatory Speed Limiter Device (SLD) requirement for commercial vehicles. This decision provides transport operators with additional time to achieve compliance following feedback from major fleet owners, who noted that they are still scheduling installations to avoid disrupting logistics operations, although the ministry did not explicitly specify the duration of this grace period.
However, the ministry clarified that this deferral was not an exemption. All operating companies, commercial vehicle owners, logistics operators, bus operators, and related parties must continue to take immediate steps to ensure their vehicles are fitted with SLDs according to the prescribed technical requirements. The ministry has appointed 25 companies to conduct retrofit installations, with a full list of authorised providers available on the JPJ portal.
During this grace period, the Road Transport Department (JPJ) will continue to monitor compliance. Operators found to have neglected the necessary steps will face interim measures, including a Notice to Attend an Investigation or a Notice 114. Once the grace period expires, formal enforcement action will be taken against any non-compliant company or owner.
Furthermore, the ministry reminded the industry that the government previously introduced the Accelerated Capital Allowance facility in Budget 2026 to assist companies with installation costs.
Originally, this enforcement rollout was scheduled to take place in phases. The mandate was set to begin on 1 October 2025 for all heavy vehicles manufactured on or after 1 January 2015. For vehicles manufactured before 1 January 2015, enforcement was scheduled to begin on 1 January 2026, whilst any remaining vehicles without an SLD were given until July 2026 to complete installation.

As part of the active enforcement rules, heavy vehicles must carry their SLD Functionality Verification Certification and reports inside the cabin at all times. This documentation requires renewal every two years at either the Motor Vehicle Inspection Centre (PPKM) or the Public Land Transport Agency (APAD).
Sourcing the required report depends entirely on vehicle age. For heavy vehicles manufactured on or after 1 January 2015, owners can obtain the certification directly from the manufacturer, a JPJ-recognised workshop, a recognised Technical Service, or a Certified Certification Body recognised by JPJ.
Older heavy vehicles manufactured before 1 January 2015 that already feature a built-in speed limit system within their electronic control unit (ECU) simply need to have the functionality activated via a plug-in device at an approved manufacturer or designated third-party facility.
