We thank Mr Casey Lin Mee Huat for his feedback (Every road should have speed limit signs,  Aug 29). 

The default speed limit of roads, including private residential estates, in Singapore is 50km/h, unless otherwise stated. Where speed limits differ, signs are installed to inform road users of the speed limit. In areas such as Friendly Streets, School Zones and Silver Zones where speed limits are lower to ensure safety for pedestrians, especially school-going children and senior pedestrians, speed limit signs and road markings are clearly displayed to alert motorists. Our approach is consistent with international practice.   

For safety reasons, all traffic light junctions in Singapore have a standardised amber light duration to provide consistency to motorists to slow down before a red light. Additionally, we have built-in an all-red traffic light phase after each traffic signal phase to ensure that motorists have cleared the junction before traffic from another direction can proceed. 

LTA will continue to review our road design and measures as safety remains our top priority. Road users can also play their part by observing good road safety practices and adhering to traffic rules.
