A Speed Limiter Device (SLD) is an electronic system that limits the maximum speed of a commercial vehicle. In Malaysia, JPJ requires commercial vehicles to comply with SLD regulations to improve road safety.

Commercial vehicles that fall under JPJ's Speed Limiter Device requirements must have a compliant SLD installed according to the official JPJ implementation schedule. Contact Andrew at 018-2538686 with your registration number and year of manufacture for verification.

For applicable commercial vehicles, the Speed Limiter Device limits maximum vehicle speed to 90 km/h.

Most SLD installations are completed within 1 to 3 hours, depending on the vehicle model and condition.

6. Do I need to make an appointment?

Yes. We recommend making an appointment in advance. Please prepare your preferred installation date, a copy of the vehicle registration (Geran), and your contact details.
