Emerging at T-Junctions
Emerging safely from a minor road into a major road requires careful speed control, systematic observation using the MSPSL and LADA routines, and precise judgement of traffic flow. Learn how to identify junctions early, give way correctly, and move out smoothly into traffic without causing others to slow down or swerve.

Knowledge: Road priority, regulatory signs, and road markings
When emerging at a T-junction, traffic on the road you are joining almost always has absolute priority. Junctions are governed by distinct statutory road signs and road markings. A give-way junction is signed by an upside-down triangular sign ('GIVE WAY') and marked by double broken white lines across your lane; you must slow down and give way to all crossing traffic, stopping if necessary. A stop junction is signed by an octagonal red sign ('STOP') and marked by a solid thick white line; you must bring your car to a complete, stationary halt before the line, regardless of whether any vehicles are visible. Approaching any junction requires the MSPSL routine (Mirrors, Signal, Position, Speed, Look) to ensure you arrive under complete control in 2nd or 1st gear.
Understanding: Why safe gap selection and creeping forward matter
Crossing or joining a live traffic stream is one of the highest-risk moments in driving because you are entering the path of vehicles travelling at higher speeds. Pulling out into an inadequate gap forces other road users to brake or swerve, which creates instant collision danger. Furthermore, many British junctions are 'closed' or blind, with sightlines blocked by hedges, walls, fences, or parked vehicles. Rushing forward blindly invites disaster. By applying 'peep and creep'—slipping the clutch in 1st gear at a walking pace with your foot covering the brake—you gradually position your eyeline forward until you gain a clear view of both directions before committing to move. Understanding the LADA cycle (Look, Assess, Decide, Act) allows you to continuously evaluate changing speeds of approaching vehicles, including narrow, fast-moving hazards like motorcycles and cyclists.
T-Junction Priority & Signage
Give Way
Inverted Triangle Sign
Marked by double broken white lines across your lane. You must give way to all major road traffic, stopping when necessary.
Stop Sign
Octagonal Red Sign
Marked by a solid thick white line. You must bring the vehicle to a full, stationary halt before the line in all conditions.
The LADA Routine at Junctions
How to Spot a Junction Before You Emerge
You can only emerge safely if you notice the T-junction early. When approaching on a minor road, look well ahead and use these five clues to work out that a junction is coming up before you start the MSPSL routine.
1. Road signs
Look for a red-bordered triangular warning sign showing a T-junction ahead: a vertical stem ending at a horizontal crossbar. As you get closer, look for Give Way signs (an upside-down triangle) or Stop signs (an octagon), as well as advance warning signs such as 'Give Way 50 yds' or 'Stop 100 yds'.
2. Gaps in buildings
Look at the line of houses, walls, hedges and fences along your road. A break where the buildings or boundaries end, open up, or run horizontally across the end of your road shows that you are reaching a junction.
- Look for a break where the line of houses, hedges, walls or fences ends or opens up ahead
- Look for the road ahead ending at a wall, hedge, fence or building facing you
- Look for a wide gap or lighter sky ahead where cross-streets meet your road
3. Road markings
The road surface gives clear advance clues. Scan the carriageway ahead for markings that indicate you are coming up to a give-way or stop line.
- Double broken white lines across your lane marking the Give Way line at the junction mouth
- A solid white line across your lane, sometimes with the word STOP painted on the road surface
- Hazard warning lines: the centre line dashes become noticeably longer with shorter gaps between them
- Double yellow lines curving around the corners at the mouth of the junction
- The white centre line of the major road crossing in front of you ahead
4. Cars entering and leaving
Watch the movement of traffic ahead. Vehicles crossing horizontally across the end of your road are a clear signal that a major road crosses ahead.
- Look for vehicles crossing from left to right or right to left across the end of your road
- Look for cars waiting to emerge or slowing down to turn into your road
- Look for brake lights or indicators on vehicles ahead of you as they slow down for the junction
5. Open or closed junction?
As soon as you spot the junction, decide whether it is open or closed. This is about how much you can see along the major road in both directions, and it sets your approach speed.
An open junction gives you a wide, clear view early, before you reach the junction. A closed junction has a blocked view: remember BBBV, which is Buildings, Bushes, Bricks (walls) and Vehicles (such as parked cars and vans).
- Open: you have a clear view both ways early on approach, so approach at a controlled pace in 2nd gear and be ready to stop at the line if traffic is coming
- Closed: your view is blocked by BBBV hazards, so slow down much earlier, select 1st gear, and be ready to peep and creep forward (see the Skills steps below)
- Open describes what you can see, not how busy the road is
Once you have spotted the junction and decided whether it is open or closed, start the MSPSL routine for emerging: Mirrors, Signal, Position, Speed, Look.
Syllabus, Highway Code & Test Requirements
How this lesson aligns with the official national driving standards and practical test assessments in Great Britain.
- Approach junctions at a controlled speed using the MSPSL routine in good time
- Correctly identify give-way lines, stop lines, and road signage, stopping completely at stop signs
- Position the vehicle correctly according to whether emerging left or right
- Assess gaps accurately to both left and right without causing priority traffic to brake or alter course
Highway Code: Junctions (rule 170)
Watch out for pedestrians crossing junction entrances, cyclists, and motorcyclists. You must give way to traffic on the main road and stop at STOP signs.
Highway Code: Road markings and signs
Double dashed give-way lines require yielding priority; single solid stop line accompanied by the octagonal stop sign demands a complete stationary halt.
Highway Code: Using the road
When turning right into a main road, wait until there is a safe gap between traffic coming from both directions before moving out.

- Driving test assessment sheet section: 'Junctions – Approach speed and control'
- Driving test assessment sheet section: 'Junctions – Turning right / Turning left'
Skills: Step-by-step routine for emerging safely
Follow this proven sequence whenever you approach a T-junction to turn left or right into a major road.
Check interior mirror and corresponding door mirror (left mirror for turning left, right mirror for turning right) well before the turn. Apply your indicator in good time—roughly 3 to 5 car lengths away—without misleading other road users about earlier side roads or driveways.
For turning left, maintain your normal road position roughly 1 metre from the kerb, following the line of the corner. For turning right, position your vehicle just to the left of the centre line (or the middle of the road on unmarked roads), leaving room for oncoming traffic to pass.
Brake smoothly early on approach. At an open junction with clear visibility in both directions, select 2nd gear while rolling at around 5–10 mph. If the junction is closed, blind, or busy, slow down to a crawl and select 1st gear before reaching the give-way markings.
Look right, then look left, then right again. Assess the speed, distance, and intentions of approaching vehicles, including pedal cyclists, motorbikes, and pedestrians. Decide whether a genuine safe gap exists, or whether to hold back.
If hedges, parked cars, or fences obstruct your view, bring the car to a crawl in 1st gear. Use precise clutch control at the biting point, creeping forward centimetres at a time with your foot covering the footbrake until your eyes can see past the obstruction.
Judging when to move out can feel daunting when you first start learning. If you are crossing or joining the path of traffic, use the walk-across rule to help judge whether your gap is genuinely safe. See the panels below for how this rule works in practice.
Walk across, drive across
When you are crossing the path of traffic, a common rule used by approved driving instructors (ADIs) is: if you can walk across, then you can drive across.
For example, imagine you are turning right and oncoming traffic is stopping you from going. Picture yourself walking across the road. If you could comfortably walk across without rushing, that gives you a good idea you have enough time to drive across.
The double rule: walk across and back
When you are not just crossing but joining the traffic stream in front of approaching traffic—such as turning left at a T-junction with a car coming from your right—you need to leave about twice as much time. This is because you must accelerate up to the speed of that traffic.
The guideline here is that you could comfortably walk across the road and back again before that car reaches you.
It is vitally important to leave a big enough gap to accelerate up to the speed of the traffic before the approaching car catches up behind you.
The three S's: Swerve, Slow down, Stop
You must never pull out in front of an approaching vehicle and cause it to swerve, slow down or stop.
Causing another driver to stop or swerve is likely to be an immediate test fail. Causing someone to slow down will definitely be marked as a minor fault, and could also be recorded as a serious or dangerous fault at the discretion of the examiner or driving instructor, so avoid it altogether.
Learners sometimes joke that the real rule is to avoid making someone 'slow down, swerve or swear'—the unofficial fourth S! But the official DVSA guidance focuses strictly on swerve, slow down or stop.
Walk across, drive across: judging the gap
Once you confirm a safe gap in both directions, release the handbrake (if applied), bring the clutch up smoothly with brisk acceleration, steer neatly into your lane without cutting the corner or swinging wide, cancel your indicator, check your interior mirror, and build normal road speed.

Practice Steps
Core Essentials & Examiner Criteria
What you must get right every time, paired with what the driving examiner marks on your practical test.
What You Must Get Right
Always apply the MSPSL routine systematically well before arriving at the give-way line
You must come to a total stationary halt at every octagonal STOP sign and line, regardless of road conditions
Look right, left, and right again; keep your eyes moving and lean forward slightly to look past windscreen pillars
Never pull out if an approaching vehicle would need to brake, swerve, or take evasive action to avoid you
When turning right, you need a safe gap in both directions simultaneously before committing to emerge
Accelerate positively and progressively once emerging into your lane to match the speed of circulating traffic
What the Examiner Looks For
Effective all-round observation before emerging, including checking for pedestrians crossing the mouth of the junction
Approaching at an appropriate, controlled speed so you can stop safely without crossing the give-way line if traffic approaches
Correct road positioning: close to the kerb for left turns and near the centre line for right turns
Confident, timely gap selection without unnecessary hesitation when a safe, clear gap presents itself
Smooth vehicle control without stalling, rolling backwards, or cutting the corner when entering the new road
Common Mistakes, Test Failures & Safety Tips
Understand how small slips become driving test faults, and how to keep every manoeuvre safe.
Common Learner Mistakes
Looking only in one direction
Only checking right when turning left, or forgetting that a car from the left could be overtaking a cyclist on the major road and travelling on your side of the carriageway.
Rolling through a STOP sign or give-way line
Failing to stop completely at an octagonal STOP sign, or letting the vehicle's nose creep over the give-way line into live traffic before stopping.
Misjudging approaching vehicle speed
Looking only at how far away a vehicle is rather than how fast it is closing down on you, especially fast-approaching motorcycles.
Cutting the corner on right turns
Steering too early into the major road and cutting across the lane of oncoming vehicles rather than driving to the centre point of the junction before turning.
Essential Safety Tips
Look twice for two wheels
Motorcycles and bicycles are narrower and easily hidden behind your car's windscreen pillars (A-pillars) or street furniture. Always double-check before moving.
Never rely purely on another driver's flashing lights or signal
A driver on the main road flashing their lights or indicating left might not be turning, or their indicator might have been left on accidentally. Wait until they physically commit to turning before you emerge.
Watch for pedestrians crossing the side road
Under Highway Code priority rules, pedestrians crossing or waiting to cross the junction road you are emerging from have priority. Check your blind spots.
Master the clutch bite before creeping forward
At blind junctions, find the clutch biting point with the car held still before releasing the footbrake, ensuring you never roll backwards on slight inclines.
Common Causes of Test Failure
How driving examiners categorise errors under the DVSA marking system:
Minor (Driving Faults)
Not potentially dangerous, but marked if repeated.
Approaching slightly too quickly but stopping in time
Harsh braking just before the give-way line because the approach speed was too high, but maintaining vehicle control and not crossing the line.
Hesitation on an obvious, generous gap
Holding back at a clear, open junction when multiple ample gaps were available, causing unnecessary delay to following drivers.
Serious Faults
Potentially dangerous; results in a test failure.
Pulling out and forcing priority traffic to slow down
Emerging into the major road and causing an approaching vehicle to lift off the accelerator, brake, or change road position.
Failing to stop at a marked STOP sign
Treating an octagonal STOP sign as a Give Way by merely slowing down and rolling through without coming to a complete stop.
Dangerous Faults
Actual danger to you, examiner, or other road users.
Pulling directly into the path of oncoming traffic
Emerging blindly into oncoming vehicles, requiring immediate emergency intervention by the examiner on the dual controls to prevent a collision.
