Had Laju Kebangsaan (National Speed Limits) is a set of speed limits applicable on Malaysian expressways, federal roads, state roads and municipal roads. Like any other countries in the world, failing to obey the speed limit on Malaysian roads and expressways is an offence as subject to Malaysian Road Safety Act 1987, which can be fined up to RM300, depending on the difference between the speed limit and the driven speed.
Default speed limits
- Expressways: 110 km/h (70 mph) by default, but may be reduced to 80 or 90 km/h (50-55 mph) at dangerous mountainous stretches, crosswind areas and urban areas with high traffic capacity.
- Federal roads: 90 km/h (55 mph) by default (reduced to 80 km/h), 60 km/h (40 mph) in town area.
- State roads: 90 km/h (55 mph) by default (reduced to 80 km/h during festive seasons), 60 km/h (40 mph) in town area.
Speed limits for heavy vehicles
Special speed limits are applied to heavy vehicles, and all heavy vehicles have speed limit stickers describing the allowed speed limits. However, many heavy vehicles especially express buses don't obey those speed limits.
The speed limits for heavy vehicles are as follows:-
- Expressways: 80-90 km/h (50-55 mph)
- Federal and state roads: 70-80 km/h (45-50 mph) by default, 60 km/h (40 mph) in urban areas
Other speed limits
For school areas, the speed limit of 35 km/h (20 mph) is applicable during rush hours. Besides, cars with trailers apply the same speed limit as heavier vehicles (80 km/h (50 mph) on expressways and 80 km/h (50 mph) on other roads).
Starting from the 2006 Hari Raya Aidilfitri, the Malaysian Police began enforcing lower speed limits during festive seasons for all federal and state roads, from the default 90 km/h (55 mph) down to 80 km/h (50 mph).
