What Is a T-Junction? (UK Driving Guide)

A T-junction is a road junction where one road meets another at a right angle, forming the shape of the letter T. The road that ends is called the minor road (the bottom of the T), and the road it meets is called the major road (the top of the T). Drivers on the minor road must give way to traffic on the major road unless road markings or signs say otherwise. T-junctions are one of the most common junction types you will encounter – and one of the most common places where faults are recorded on the driving test.

How to identify a T-junction

T-junctions are marked in several ways:

• A “T” junction ahead sign – a white rectangular sign with a thick T shape, warning that the road ahead ends at a junction
• Give Way lines – double dashed white lines across the road at the point where you must stop and assess
• A “Give Way” triangle sign – an inverted red triangle on approach to the junction
• GIVE WAY painted on the road surface in large letters

In some cases, particularly on busier or more hazardous junctions, the give-way lines are replaced by solid white stop lines and a “STOP” sign – meaning you must come to a complete stop regardless of whether any traffic is visible.

Who has priority at a T-junction?

Traffic on the major road (the top of the T) always has priority. Drivers emerging from the minor road must wait until it is safe to pull out, regardless of how long they have been waiting. There is no rule that says another driver must let you out after a certain number of vehicles have passed.

The only exceptions are where specific signs or signals change the priority:

• Traffic lights override the standard give-way rule
• A police officer or traffic warden directing traffic overrides standard priority
• A “Priority Road” sign on the minor road can occasionally indicate changed priority, though this is uncommon in the UK

How to approach a T-junction correctly

The Mirror-Signal-Manoeuvre (MSM) routine applies to every junction approach. In practice:

1. Check your mirrors as you identify the junction ahead
2. Signal your intended direction (left or right) in good time
3. Reduce speed progressively – do not brake sharply at the last moment
4. Select an appropriate gear – typically second gear on approach, first if you are stopping
5. Position your car – for a right turn, keep to the left side of your lane (unless a turn lane is marked); for a left turn, stay to the left
6. Stop at or before the give-way line and assess both directions of the major road before pulling out
7. Look both ways – left, right, and left again – before emerging. On a right turn you will cross oncoming traffic, so assess the gap carefully before committing

Closed and open junctions

Instructors distinguish between two types of T-junction by visibility:

• An open junction is one where you can see clearly in both directions while still on the approach, well before the give-way line. You may be able to continue without stopping fully if it is clearly safe.
• A closed junction is one where vision is blocked by buildings, hedges, parked vehicles or a steep hill until you are at or past the give-way line. You must creep forward slowly and stop again at the point where you can see properly.

Treating every closed junction as open is one of the most common causes of serious collisions at T-junctions, and a reliable way to collect a serious fault on test.

Common T-junction mistakes on the driving test

• Emerging without adequate observation – particularly failing to check right for oncoming traffic before turning right
• Rolling through a give-way without actually stopping and assessing when vision is restricted
• Stalling due to poor clutch control when pulling away from a stop
• Cutting the corner on a right turn, swinging into the path of oncoming traffic on the major road
• Taking too long to emerge when a clear safe gap is available – hesitation that causes vehicles behind to queue can result in a minor fault
• Poor road position on approach, particularly drifting right before a left turn

T-junctions on the driving test

Examiners assess junction handling throughout the test, not just at one location. You will typically encounter several T-junctions on any route. What examiners look for is consistent MSM routine, appropriate speed on approach, full observation before emerging, and clean pulls away without stalling or hesitation once the gap is taken.

You do not need to be fast – you need to be safe and systematic. A brief pause to check both ways is expected. A long stop because you misjudged a gap or failed to look properly is a fault. If you are aiming to be test-ready quickly, our fast-track driving test guide explains how intensive practice compresses skills like junction handling into a short, focused window.

Our guide to passing your driving test first time covers junction handling alongside the other common fault areas, and our step-by-step process explains how we build junction confidence progressively across your course. If you are learning from scratch, our intensive course for complete beginners introduces junctions step by step alongside everything else you need. If you have had lessons elsewhere and want focused work on junctions specifically, our Improver course lets us concentrate on the areas where you’re losing marks rather than repeating what you already do well.
