User:Kadyus/Speed Limit Guidelines for Malaysia View history

Speed Limit (SL) is a regulatory traffic control means enacted under Section 69 of the Road Transport Act 1989 (Act 333) which is necessary to control the speed of vehicles for safety reasons. It is implemented by the road authorities to inform the motorists of the appropriate driving speeds and these limits are enforced by the police or road transport authorities.

Types of Speed Limits

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), state roads (90 km/h) and municipal roads in town area (60km/h) [TBC].

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.
