When merging into a lane without lane markings, the vehicle that is behind must give way to the vehicle ahead. This means the vehicle already in the lane or slightly ahead has the right of way, and the merging driver must yield and merge safely behind them. This is sometimes called a "zipper merge" where vehicles alternate merging, giving priority to the car in front. It is important to indicate before merging and check blind spots to merge safely. In summary:
- No lane markings: the car in front has the right of way.
- The merging vehicle must give way and merge behind safely.
- Use indicators and check surroundings before merging.
This is a common rule in countries like Australia and New Zealand and aligns with road safety regulations there.
