Safety – we restrict right-hand turn access in order to keep the road as safe as possible and avoid cars crossing multiple lanes of traffic. ‘Left-in’ and ‘left-out only’ is safer. Reducing the number of right-hand turns across multiple lanes of traffic also reduces the chance of side impact collisions (often called ‘T-bones’).
Improved traffic flow – when we control the places where cars can turn right, we reduce congestion by minimising the ‘queues’ that may form behind them. This improves traffic flow and helps minimise congestion.
