Types of Speed Limits link to this section


Statutory Speed Limit
Statutory speed limits, also known as the National Speed Limits (Had Laju Kebangsaan), are based on the concept that uniform categories of highways can operate at certain maximum speed under ideal conditions. The National Speed Limits are applicable to expressways (110 km/h), federal roads (90 km/h) and state roads (80 km/h).

Common examples of Statutory SL Signs



Local/Zonal Speed Limit
These alternative speed limits are usually lower than those prescribed by the National Speed Limit. Legislated through the process of gazette, these speed limits are established on basis of engineering study, and becoming effective when the limits are posted and properly recorded.

Common examples of Local/Zonal SL Signs



Advisory Speed Limit
Advisory Speed Limit is usually recommended by the road authority, but is not strictly enforced. These speed limits are often set in areas with many pedestrian activities (school zones) and on difficult stretches of roads such as on speed bumps, tight corners or through roadwork zones.
