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.

'''<big>Priority of setting speed limit (SL) for the segments are as follows:</big>'''


#  Visible signage of the speed limit has the highest priority. If the road has various speed limits, we may apply the relative speed limit at the point where the speed limit signboard is located.
=={{@|Which speed limit should be added to the map?}}==

#  If there's no visible signage, then the speed limit before or after the same type of segment that has speed limit can be applied for use onto this road.
#  If the current road (A -> B) has no speed limit but the opposite road (B -> A) of the same name and type has speed limit signage, we may apply the opposite speed limit to the current road.
#  If the road has no visible signage but a nearby road of the same type with similar layout/criteria has the speed limit, then we may 'borrow' this speed limit.
#  If no speed limit signage around to be applied for reference, not even before and after the segment, then we shall follow the recommended speed limit from '''"No visible speed limit signage"'''

#  Recommended SL for “No visible speed limit signage” is merely a '''''SUGGESTIVE speed limit''''' and should not be an absolute guide, Waze or any of its associated parties will not take responsibility from issues arising from it. When in conflicts, the actual/updated speed limit by Kementerian Kerja Raya Malaysia shall be the primary reference.

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.

Which speed limit should be added to the map? link to this section

  1. All Statutory Speed Limits with or without posted sign
  2. Local/Zonal Speed Limits with posted sign
  3. Only school zones Advisory Speed Limit


IMPORTANT:

  • Local/Zonal SL marked with black lettering on a red circular sign takes precedence over Statutory SL.
  • Roadwork zones SL are NOT to be added


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.

Common examples of Advisory SL Signs
