Definition
Traffic lights regulate traffic at intersections, pedestrian crossings, level crossings and reversible lanes. The main lights are: red (mandatory stop), steady amber (stop if you can do so safely), green (proceed with care), flashing amber (caution, may pass), and flashing red (level crossing or works: mandatory stop).
Key facts
- Priority order: officer > traffic light > circumstantial signs > vertical signs > road markings.
- Steady amber: stop before the light unless you're so close braking would be unsafe.
- Red: mandatory stop before the stop line, or before entering the intersection if no line.
- Running a red light: serious offence, €200 fine and 4 points.
