Frequently Asked Questions About SLD
Still have questions?
WhatsApp us — we’ll answer and confirm your vehicle’s status, free.
WhatsApp usMy lorries are based in Kuala Lumpur but run to Port Klang daily — where should I install the SLD?+
Not a problem. We arrange installation with JPJ-recognised workshops around the Klang Valley, so you can pick the slot closest to your daily route — whether within KL itself or along the port run. WhatsApp us and we will check the most convenient option for you.
Will an SLD affect driving in Kuala Lumpur's heavy city traffic?+
No. The SLD only caps top speed at 90 km/h under UN R89 — it does not reduce engine power at low speeds, so everyday driving on KL's city roads feels exactly the same. You only notice it on the highway.
Has SLD enforcement already started in Kuala Lumpur?+
Enforcement is phased, and the retrofit phase is currently in a grace period — but the mandate stands. KL operators who install early avoid the last-minute rush for workshop slots. Don't wait for a summons — WhatsApp us for a quote and booking.
What is an SLD (speed limiter)?+
An SLD or speed limiter is an electronic device that caps a vehicle’s top speed at 90 km/h (with an 85 km/h warning), complying with the international UN R89 standard.
Is SLD mandatory in Malaysia?+
Yes, for certain commercial vehicle categories — goods lorries over 3,500 kg and buses — under JPJ’s phased enforcement (Oct 2025, Jan 2026, Jul 2026).
Which vehicles need SLD?+
Lorries over 3,500 kg, prime movers, trailers, express/tour/factory/school buses and related commercial vehicles. WhatsApp us to confirm your vehicle’s status.
