Proportion of Keep-Left Summonses Involving Slow Vehicles and Detection of Lane Discipline Offences

Mr Fadli Fawzi asked 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.

Mr K Shanmugam: 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.

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