Which traffic light to watch when going straight into the auxiliary lane?

[FrankFitz]

Watch the straight-ahead traffic light when going straight into the auxiliary lane. Precautions for vehicle driving are as follows: 1. Yielding: When there are traffic signs and markings, yield to the party with priority; when there are no traffic signs or markings, stop and look before entering the intersection, yielding to vehicles coming from the right; turning motor vehicles must yield to vehicles going straight; motor vehicles turning right from opposite directions must yield to vehicles turning left. 2. Prohibitions: Motor vehicles are prohibited from reversing at railway crossings, intersections, one-way roads, bridges, sharp curves, steep slopes, or tunnels. Motor vehicles may make U-turns at locations where there are no prohibitive signs or markings against U-turns or left turns, but must not obstruct the passage of other normally moving vehicles and pedestrians.
