Warning and guidance markings

Use advance arrows, lane lines and symbols before you reach the decision point.

Practice questions

Recognise changes in the road before the restriction

The railway-crossing marking warns of a railway crossing ahead: reduce speed and prepare to obey the crossing control. Continuity lines identify a lane diverging from the main route; decide early whether to continue or leave because a solid channelising line may follow.

Dividing lines separate opposing traffic. The reversible-lane marking identifies a reversible lane whose permitted direction changes; lane-control signals decide whether you may use it. The fact that no oncoming vehicle is visible is not permission to enter a closed or opposing lane.

The yield-ahead marking warns of yield control ahead. Lane-reduction arrows identify reduction from the left, right or both sides; plan a safe merge. Advance direction arrows preview mandatory direction arrows, and the restriction-ahead marking warns that a no-overtaking or no-crossing line is approaching. Complete only a lawful, safe manoeuvre before the restriction begins - do not accelerate to beat the line.

  • The arrestor-bed marking identifies an arrestor bed ahead for brake-failure emergencies. Keep its access clear and do not use it as a stopping bay.
  • The speed-hump marking identifies a speed hump. Reduce speed before the hump, maintain control and look for people or obstacles on the far side.

Guidance helps you keep the intended path

Lane lines divide traffic travelling in the same direction. Cross them only for a safe, lawful lane change. Guide lines through a junction help drivers follow the correct path without drifting into an adjacent turning lane.

Bifurcation arrows show how the roadway divides. Information arrows give directional guidance. Unlike mandatory arrows, an information arrow does not itself impose the same regulatory movement, but other signs or solid markings may still restrict you.

The bicycle-crossing marking shows where cyclists cross; look for cyclists crossing your path. Painted symbols identify the indicated use or information: a bicycle, airport direction or disability symbol has to be interpreted in its marked context. An aeroplane guidance symbol is not a reservation of the road for aircraft.

Word markings such as STOP or SCHOOL reinforce the control or warn of the situation. Read them early enough to act, and obey the corresponding control at its proper line rather than stopping on top of the painted word.
