About The three-colour traffic light: green, yellow, red — and its limits: which statement is correct?
On a yellow light you must always stop, even if you have already approached the junction too closely to brake safely.
On a green light you may always enter the junction, even if the far side is already jammed with stationary traffic.
The bicycle light applies to cyclists, moped riders on a cycle/moped path and drivers of a mobility scooter, not to other traffic.
An illuminated arrow in the traffic light applies to every direction of travel on that lane, not only the direction the arrow points.
Explanation
trap: shared junction, shared light. The bicycle light applies to cyclists, moped riders on a cycle/moped path and drivers of a mobility scooter, not to other traffic. The driver follows their own light
