1. Traffic lights

Traffic lights use coloured lights, arrows or symbols to regulate when road users may proceed, must prepare to stop or must remain stopped. Separate signals may apply to particular directions, lanes, pedestrians, cyclists or public-transport vehicles.

A green light permits movement only when the route is clear and the movement is otherwise legal. Road users must still follow priority rules, turning restrictions, lane markings and instructions from authorised traffic controllers.

What must a driver do at red, amber and green signals in Ireland?

Red means stop at the applicable line. Amber generally warns that the signal is changing and calls for a stop where it can be made safely; do not accelerate to beat it. Green allows movement only when the way is clear. Observe local arrow, flashing-signal and stop-line rules.

May you turn at a red traffic light in Ireland?

A red light alone means stop. A green filter arrow can permit movement in its direction even when the full red light is showing, provided it is safe and clear. A flashing amber left arrow requires giving way to conflicting traffic and pedestrians before proceeding. Do not infer an unrestricted turn-on-red permission.

Can a green light remove the need to give way to pedestrians in Ireland?

No. A green signal is not a guarantee that the junction is empty. Check for people already crossing, vehicles completing a movement and any separate pedestrian, bicycle or turning signals. Do not enter if you cannot clear the junction safely.
