T Junctions Explained
T-Junctions Explained
A T-junction is where one road comes to an end and joins another road, forming the shape of a letter T. In most cases, traffic travelling along the road at the top of the T has priority, while traffic approaching from the minor road must give way before joining or crossing the major road.
As you approach a T-junction, look for signs and road markings that tell you what is expected. You may see:
A STOP sign with a solid white stop line
A GIVE WAY sign with give way markings
Give way road markings without a sign
No signs or road markings at all
Some quieter roads have completely unmarked junctions, so don't rely solely on signs. Look well ahead, identify the junction early and assess the road layout as you approach.
What Will Be Expected on Your Driving Test?
When dealing with a T-junction on your driving test, the examiner will expect you to recognise the junction in good time and deal with it safely. You should:
Use the MSPSGL routine – Mirrors, Signal, Position, Speed, Gears and Look
Follow the correct rules when approaching, emerging from or turning at the junction
Position the car correctly
Approach at a suitable speed
Understand who has priority and give way when required
Make effective observations before moving
Pull away safely, smoothly and under control
The important thing is not simply remembering a routine. You need to use the routine to give yourself enough time to assess the junction and make a safe decision.
Give Way and Stop Signs
Give Way and Stop Signs
A Give Way sign means you must give priority to traffic on the road you are joining. You don't automatically have to stop, but you must slow down sufficiently to assess the situation and stop if necessary.
A STOP sign is different. You must stop at the solid white stop line, even if the road appears to be clear. Once stopped, make effective observations and only proceed when it is safe.
Unmarked Junctions
Unmarked T-Junctions
An unmarked T-junction has no Give Way or Stop sign and no road markings to show which road has priority. They are most commonly found on quieter residential or rural roads, so you need to identify the junction from the road layout rather than relying on signs and markings.
Approach slowly and be prepared to stop, because you should not assume that you have priority simply because your road appears wider or busier. Look carefully in all directions for other vehicles, cyclists and pedestrians, and only proceed when you are satisfied it is safe. Other road users may also be unsure who should go first, so good observation, a cautious approach and being prepared to give way are particularly important.
Open and Closed T-Junctions
Open and Closed T-Junctions
T-junctions are often described as either open or closed. Understanding the difference can help you judge the speed at which you should approach.
At an open junction, you can usually see reasonably well into the road you are joining as you approach. There may be very few buildings, hedges, parked vehicles or other obstructions blocking your view.
At a closed junction, your view is restricted. Buildings, walls, fences, hedges, parked vehicles or the shape of the road may prevent you from seeing approaching traffic until you are much closer to the junction.
This means your approach speed should reflect what you can actually see. The less you can see, the more slowly and cautiously you will normally need to approach.
Approaching a T-Junction
Approaching a T-Junction
Use the MSPSGL routine as you approach. Check your mirrors, signal if necessary, position correctly and reduce your speed early enough to remain in full control.
As you get closer to the junction, your attention should increasingly be on what you can see on the road you are about to join. Look both left and right and continue scanning rather than relying on one quick glance.
The aim is to build up a picture of what is happening. Look for approaching vehicles, cyclists, pedestrians, parked vehicles and anything else that could affect your decision.
Emerging at a T-Junction
Emerging simply means joining a major road from a minor road.
Your view of the major road will usually improve as you move towards the end of the minor road. At a closed junction, however, you may not be able to make a reliable decision until you are very close to the junction and your eye line has moved beyond the obstruction.
Don't make the decision too early.
Approach slowly enough to give yourself time to look properly. If your view is restricted, you may need to edge forward carefully until you can see sufficiently in both directions.
Minimum Observations at Junctions
Look Both Ways Before Emerging - this means Right, ahead, left,ahead, right
Always make effective observations in both directions before emerging.
This is particularly important when turning left. It can be tempting to concentrate mainly on traffic approaching from your right, but you also need to check to the left.
A vehicle approaching from your left could be overtaking, passing a parked vehicle or other obstruction, or simply positioned further towards your side of the road than expected. Emerging without checking could put you directly into its path.
At a closed T-junction, remember that you cannot make a safe decision based on what you think is happening beyond the obstruction. Approach slowly, improve your view and only emerge once you can see that it is safe.
If you can't see, you can't safely decide.
