Junctions Theory Test Guide

Junctions are where learners have to put observation, priority and timing together. This guide keeps it clear, so you know what to look for before you answer the question.

What this topic is really testing

Most junction questions are testing whether you can slow down early, read signs and markings, give way correctly and avoid blocking other traffic.

PriorityKnow who should go first
ObservationLook both ways before moving
PositionUse the correct lane and road position

What you’ll be tested on

  • Giving way at T-junctions and crossroads
  • Using box junctions correctly
  • Reading stop and give-way lines
  • Choosing a safe gap before emerging
  • Dealing with vehicles turning across your path
Instructor insight

What I see learners get wrong in lessons

At junctions, learners often focus on who has priority but forget that priority does not remove responsibility.

  • Observation should happen before movement, not while the car is already crossing the junction.
  • Parked vehicles, cyclists, pedestrians and poor visibility can change the safest decision.
  • Creeping forward can help visibility, but only if it is slow, controlled and does not force others to react.

T-junctions and crossroads

At a T-junction, traffic on the main road normally has priority. At crossroads, look carefully for signs, road markings and vehicles turning across you.

  • Slow down early enough to assess the junction.
  • Check both directions before emerging.
  • Do not assume another driver has seen you.

Box junctions

A box junction is there to keep traffic moving. You should not enter unless your exit is clear, unless you are turning right and waiting for oncoming traffic to clear.

  • Look beyond the yellow box before entering.
  • Do not follow traffic in just because the vehicle ahead moves.
  • Only wait in the box when turning right and your exit is clear.

Emerging safely

Theory questions often show a driver waiting to emerge. The safe answer is usually the patient answer: observe properly, wait for a clear gap and avoid forcing others to brake.

Common mistakes

  • Rushing out because the vehicle behind is close.
  • Blocking a box junction when the exit is not clear.
  • Looking once and moving without checking again.
  • Missing give-way or stop markings on the road.

Real test tips

  • If a question includes road markings, use them before guessing priority.
  • At crossroads, think about traffic from every direction, not just the road in front.
  • If the answer involves forcing another road user to slow down sharply, it is probably wrong.

What do junction questions usually test?

They usually test priority, observation, road markings and whether you can choose a safe gap.

Can you wait in a box junction?

Only in limited circumstances, usually when turning right and waiting for oncoming traffic while your exit is clear.
