Speed Limiter for Singapore

By In Blog On March 6, 2024

The speed limiter regime aims to improve road safety and driving behaviour. It complements other measures intended to reduce fatalities and injuries among all road users.

Under Singapore’s laws, it is mandatory for speed limiters to be installed in the following categories of vehicles:

  1. every goods vehicle having a MLW exceeding 12,000kg and which has, or if a speed limiter is not fitted to it would have, a maximum speed exceeding 60km/h; and
  2. every public service vehicle having a MLW exceeding 10,000kg and which has, or if a speed limiter is not fitted to it would have, a maximum speed exceeding 60km/h.

Currently, lorries with a MLW between 3,501kg and 12,000kg (inclusive) are not required by law to have any speed management devices, or speed limiters. The law to have speed limiters will be expanded to all lorries in this weight category progressively over 1 January 2026 to 1 July 2027.
