About The three-colour traffic light: green, yellow, red — and its limits: which statement is correct?
On a green light you may always enter the junction, even if the far side is already jammed with stationary traffic.
An illuminated arrow in the traffic light applies to every direction of travel on that lane, not only the direction the arrow points.
A yellow flashing light only means: dangerous point, caution required.
On a yellow light you must always stop, even if you have already approached the junction too closely to brake safely.
Explanation
trap: light without function distinction. A yellow flashing light only means: dangerous point, caution required. It does not regulate right of way; that follows from the signs or the right-hand rule on site
