Number of Traffic Junctions that Allow Motorists to Make Discretionary Right Turns

Mr Ang Wei Neng asked the Minister for Transport (a) how many traffic junctions in Singapore currently allow motorists to make discretionary right turns; (b) in the last five years, what is the number of reported accidents involving discretionary right turns; and (c) of which, how many such accidents have resulted in serious injuries.

Discretionary right turns refer to right-turn movements at signalised junctions onto oncoming traffic without Red-Amber-Green (RAG) arrows. Since 2018, the Land Transport Authority (LTA) has progressively implemented RAG arrows at more than 1,200 traffic junctions. LTA is currently planning for RAG at about 200 more traffic junctions, subject to further site studies. This will further reduce the proportion of traffic junctions in Singapore that allow motorists to make discretionary right turns to less than 15% of all signalised junctions. Most of the remaining junctions are single-right turn lanes with only one lane of oncoming traffic, so the risks are lower.

Between 2019 and 2023, there were about 2,700 reported accidents at junctions with discretionary right turns. Of these, 56 accidents resulted in fatalities.
