Every driver knows that turning traffic must yield to traffic going straight. Far fewer know the situations where the straight-through vehicle must yield to one that is turning.
1. At an unsigned junction, yield to the right
Where there are no lights, the default is to let traffic from the right go first. The reason is the larger blind spot on that side: whether the vehicle from the right is going straight or turning, it has priority.
2. At signalised junctions, clear the junction first
At a light-controlled junction, if your direction has turned green but a vehicle that entered earlier is still in the junction, let it clear before you move. Vehicles already in the junction have priority to get out.
3. Where there is a give-way sign, always give way
At junctions marked with a give-way sign, you must give way to vehicles merging or turning in, whether you are going straight or crossing, because their path has priority. If there is a stop line, stop and observe the junction before proceeding. If a collision occurs, the vehicle facing the sign is held fully responsible.
4. Leaving a main road, the slip road gives way
When a vehicle leaves the main road, traffic on the slip road gives way. The blind spot on the right is larger because the separation between the two carriageways blocks the view, making it hard to see vehicles on the slip road. A vehicle leaving the main road is decelerating but still moving fast enough to cause a serious collision, so the slip road must give way.
