Junctions

Turning left at traffic lights

A left turn at lights brings pedestrians and cyclists closer to your path than almost any other manoeuvre - the green light only tells you the road ahead is yours to use, not that the kerbside is clear.

Practical test

Why it matters

This checks controlled-junction planning together with pedestrian and cyclist awareness at exactly the point where they're most likely to be close to your path.

What to look out for

Lights first, checks second

A green light means the turn may be allowed. Your own final checks are what actually decide whether to move.

Protect the kerbside

Left turns at lights bring pedestrians and cyclists close to the kerb - keep scanning before and during the turn, not just before it.

Key steps

  1. 1 Identify the left-turn lane and any lane arrows early, so you don't need to drift across at the last moment.
  2. 2 Check mirrors, signal left in good time, and reduce speed smoothly as you approach the lights.
  3. 3 Stop behind the line if required, or continue only if the signal and the road ahead genuinely allow it.
  4. 4 Before turning, check for pedestrians and cyclists near the crossing or kerbside, and for anyone emerging near the new road.
  5. 5 Turn at a controlled speed and finish in the correct position on the road you're entering.

Common mistakes

Only watching the traffic light

Use the light as permission to proceed, then still check the crossing area, kerbside, cyclists, and the road you're entering.

Approaching too quickly

Ease off early so you can stop smoothly if the lights change or someone steps towards the crossing.

Cutting the corner

Keep enough steering control to follow the kerb safely, without clipping it or swinging too wide into the new road.

Highway Code

Rule 175

You MUST stop behind the white 'Stop' line unless the light is green.

Rule 182

Use your mirrors and signal left well before you turn. Do not overtake just before turning left.
