UK road markings
Road markings work alongside signs to control traffic. The theory test asks what different lines mean, so it pays to learn the system of white and yellow markings.
Key facts to remember
- ◆ The longer the white line, the greater the hazard -- short lines mean lower risk.
- ◆ A solid white centre line means you must not cross or straddle it except in limited cases.
- ◆ A broken white centre line means you may overtake when it is safe.
- ◆ Single yellow lines at the kerb mean waiting is restricted at certain times; double yellow means no waiting at any time.
- ◆ Hatched areas bordered by a solid white line should not be entered.
Where double white lines have a solid line nearest you, do not cross or straddle it unless it is safe and you need to enter a side road or pass a stationary obstruction. Box junctions marked with yellow criss-cross lines must not be entered until your exit is clear.
