Road markings in Ireland
Road markings work alongside signs to control traffic. The theory test checks that you can read lines on the road and act on them.
Key facts to remember
- ◆ A continuous white centre line means you must not cross or straddle it to overtake.
- ◆ A broken white centre line means you may cross it when it is safe to do so.
- ◆ Double yellow lines at the edge mean no parking at any time.
- ◆ A single yellow line means parking is restricted during the times shown on nearby plates.
- ◆ You must not enter a yellow box junction unless your exit is clear.
