Additional traffic lane joining from the left ahead
Warning that traffic will be joining from the left ahead. Stay alert and be ready to adjust speed. On motorways this is a common merging situation and is frequently tested in hazard perception. Check your mirrors, consider moving to the right if safe, and maintain a safe gap. Sudden braking here can cause a chain-reaction collision.
