Mr Dennis Tan Lip Fong asked the Acting Minister for Transport whether LTA can require all contractors carrying out different works on roads provide early warning notices of at least 200 metres before work sites to allow motorists sufficient time and distance to safely change lanes ahead of lane closures for works, improving traffic efficiency and road safety.
Reply by Acting Minister for Transport Jeffrey Siow:
1. Contractors are required to provide advance warning signs at road worksites as prescribed in the Land Transport Authority's (LTA's) Code of Practice for Traffic Control at Work Zone. For example, for a road with a speed limit of 50km/h, the earliest advance warning sign should be placed around 280 metres before the worksite. For roads with higher speed limits, the Code requires advance warning signs to be placed further away from the worksite. Action is taken against contractors for non-compliance.
