Proportion of keep-left summonses involving slow vehicles and detection of lane discipline offences

Question:

Mr Fadli Fawzi: To ask the Coordinating Minister for National Security and Minister for Home Affairs (a) what proportion of summonses issued for failing to keep left on expressways involved vehicles subject to a statutory speed limit of 60 km/h or below; and (b) how such violations are detected given that fixed enforcement cameras are not currently deployed for lane discipline offences.

Answer:

Mr K Shanmugam, Coordinating Minister for National Security and Minister for Home Affairs:

1. All the summonses issued for the offence of failing to keep left on expressways have involved vehicles with a vehicular speed limit of 60 km/h or slower, since the offence in the Road Traffic (Expressway Traffic) Rules only applies to such vehicles.

2. These violations are detected through on-road enforcement by Traffic Police officers, reports submitted by members of the public, and traffic accident investigations.
