Turning right at junctions — road position and priority

Turning right is the manoeuvre that asks you to stop in the middle of a moving road, judge a gap in traffic coming the other way, and steer across it — and it is the only everyday manoeuvre where doing all three well still leaves the question of who goes first unanswered. The Highway Code gives right turns three rules, 179 to 181, and the mirror-image left turn two more, 182 and 183. Position is where most of the marks and most of the arguments go.

Incorrect positioning when turning right at junctions

That is fourth on the DVSA list of the most common reasons for failing the practical test, above traffic lights, steering and road markings. It is not a hard rule to learn. It is a hard habit to build, because the wrong version feels more comfortable in the seat.

Rule 179 — where the car goes

Well before you turn right you should use your mirrors to make sure you know the position and movement of traffic behind you; give a right-turn signal; take up a position just left of the middle of the road or in the space marked for traffic turning right; leave room for other vehicles to pass on the left, if possible.

Four instructions, in that order, and each one is doing a separate job.

The examiner’s version of the same instruction is shorter, and it is written as an expected outcome rather than as advice.

When turning right, the vehicle should be positioned to the centre of the road as is safe. The vehicle should not cut the corner when turning right.

Note the word well at the start of Rule 179. Mirror, signal and position all belong on the approach, not at the give-way line. A driver who arrives at the junction and only then starts moving right has done the manoeuvre in the wrong order, whatever the car ends up looking like from outside.

Why the swing to the left is wrong

The habit — drifting left, sometimes into the kerb, to open up the angle before swinging right — is common enough to have its own arguments. The Code closes all of them, in four separate places.

• It is the opposite of Rule 179. The rule puts you just left of the middle of the road and asks you to leave room for other vehicles to pass on the left. Moving left does the reverse of both: it takes you away from the centre and it closes the gap the rule wanted you to leave open.
• Rule 160 only ever moves you right for this. Once moving you should keep to the left, and the rule lists its own exceptions: “when you want to overtake, turn right or pass parked vehicles or pedestrians in the road”. A right turn is one of the three reasons the Code gives for leaving the left. It is never a reason to bury yourself in it.
• It makes your signal misleading. Rule 103 asks you to make sure your signals will not confuse others, and to check it is not misleading to signal at that time. A right indicator on a car moving left tells the driver behind two different things at once, and the one they can see is the steering.
• The consequences are not just advisory. Rule 144 is a MUST NOT: do not drive dangerously, without due care and attention, or without reasonable consideration for other road users, with sections 2 and 3 of the Road Traffic Act 1988 cited under it. Section 3 catches driving “without reasonable consideration for other persons using the road” — which is a fair description of taking up two lanes to make one turn.

The examiner’s judgement criteria put the same test in one line, and it is a good one to carry generally.

When turning right, other vehicles should not have to stop, slow down or swerve to allow the vehicle to complete its turn.

The exception that is real

Long vehicles genuinely do need the width, and the Code says so twice — once to warn other drivers, once to tell them what to do about it. Rule 170 asks you to watch out for long vehicles which may be turning at a junction ahead, because “they may have to use the whole width of the road to make the turn”. Rule 221 adds that large vehicles may need extra road space to turn, that the driver may not be able to see you in the mirrors if you are following, and that you should be prepared to stop and wait if the vehicle needs room or time to turn.

That exemption belongs to the vehicle, not to the manoeuvre. An articulated lorry swinging wide is following the Code. A hatchback doing the same thing is copying a shape it does not need.

Where “just left of the middle” actually is

Rule 179 gives you two positions, not one — the middle of the road, or the space marked for traffic turning right. When the junction has provided a space, that space is the answer, and it usually announces itself well before you reach it.

Areas of white diagonal stripes or chevrons painted on the road. These are to separate traffic lanes or to protect traffic turning right. If the area is bordered by a broken white line, you should not enter the area unless it is necessary and you can see that it is safe to do so. If the area is marked with chevrons and bordered by solid white lines you MUST NOT enter it except in an emergency.

The official sign guide is blunter about what those diagonal stripes in the middle of the road are for.

Diagonal white lines (hatched markings) bounded by broken lines may be used in the centre of the road to separate opposing flows of traffic. They are often provided at junctions to protect traffic turning right.

So the boundary line decides. A broken boundary means the hatched area is available to you when you need it and can see that it is safe — which is exactly the situation of waiting to turn right into a side road. Chevrons inside a solid boundary are a different marking with a MUST NOT attached, and no right turn makes entering one necessary.

Rule 143 is worth reading twice on a one-way street, because it also carries the reminder that traffic could be passing on both sides of you — routine there, and narrower on a two-way road, where Rule 163 lets a following driver overtake on the left only when the vehicle in front is signalling to turn right and there is room to do so, or pass on the left without leaving their own lane when the queue on their right is moving more slowly. The first of those is this manoeuvre: it is why Rule 179 asks you to leave room on your left, and it is what Rule 180’s second mirror-and-blind-spot check is looking for.

Rule 180 — when to go, and not cutting the corner

Wait until there is a safe gap between you and any oncoming vehicle. Watch out for cyclists, motorcyclists, pedestrians and other road users. Check your mirrors and blind spot again to make sure you are not being overtaken, then make the turn. Do not cut the corner. Take great care when turning into a main road; you will need to watch for traffic in both directions and wait for a safe gap.

Three things in that rule get skipped, and they are the same three every time.

• The second mirror check. Rule 180 asks for mirrors and blind spot again, after the wait. You may have been stationary for twenty seconds with a right signal on; someone behind may have decided to pass you. The first check told you about a road that no longer exists.
• “Do not cut the corner.” Turning right into a side road means arriving on the correct side of the new road, past the centre line of it. Cutting across the mouth of the junction puts you briefly on the wrong side of a road you cannot see far down.
• Both directions on a main road. Turning right out of a junction is two judgements, not one: a gap from the right, and a gap from the left long enough to complete the turn and get up to the speed of the road you are joining.

Rule 181 — two vehicles turning right at each other

The one every driver has an opinion about. Two cars face each other at a crossroads, both indicating right, and their paths cross. The Code names both options and does not choose between them.

When turning right at crossroads where an oncoming vehicle is also turning right, there is a choice of two methods: turn right side to right side; keep the other vehicle on your right and turn behind it. This is generally the safer method as you have a clear view of any approaching traffic when completing your turn. Left side to left side, turning in front of each other. This can block your view of oncoming vehicles, so take extra care. Cyclists and motorcyclists in particular may be hidden from your view. Road layout, markings or how the other vehicle is positioned can determine which course should be taken.

Instructors call these offside to offside and nearside to nearside — the offside of a UK car being the driver’s side and the nearside the kerb side. The Code itself never uses either word; it writes right side to right side, and left side to left side.

Two practical points the rule implies without stating.

• Read the other car, not the theory. By the time you are both in the junction, one of you has already committed to a line. Rule 181 explicitly lets the other vehicle’s position decide the method, so match it rather than insisting on the safer one and meeting in the middle.
• Left side to left side hides the exact road users Rule 180 told you to watch for. A motorcyclist coming the other way, straight on, is behind the car you are passing nose to nose. That is the specific danger the rule names.

So who has priority?

Nobody, and that is the answer rather than a gap in the answer. Rule 181 gives a choice of methods and no order of precedence. The nearest thing the Code has to a priority rule for a right turn is Rule 180’s wait until there is a safe gap between you and any oncoming vehicle — the traffic you give way to is the traffic coming towards you, whether it is going straight on or turning.

An indicator is not priority either. Rule 103 ends with the sentence in full: “Remember that signalling does not give you priority.” An oncoming right indicator tells you what that driver intends, not what they are about to do, and Rule 104 adds the usual reason a signal lies — it may simply not have been cancelled. The wider version of this argument, and where the Code’s MUSTs sit against its advice, is in MUST vs should.

Turning right at traffic lights

Lights change the sequence but not the position. Three rules do the work.

You MUST NOT move forward over the white line when the red light is showing. Only go forward when the traffic lights are green if there is room for you to clear the junction safely or you are taking up a position to turn right.

That last clause is the licence to wait inside the junction. Moving past the stop line on green to sit in the middle, indicator on, waiting for a gap in oncoming traffic, is the intended behaviour — and it is why you should still be there when the lights change, completing the turn as the oncoming flow stops.

Rule 175 is the other half: you MUST stop behind the white stop line unless the light is green, and if amber appears you may go on only if you have already crossed the line or are so close that stopping might cause a collision. A green filter arrow is narrower again — Rule 177 treats it as a filter lane, so do not enter that lane unless you want to go in the direction of the arrow, and give other traffic, especially cyclists, time and room to move into the correct lane.

Box junctions

The yellow criss-cross box has a right-turn exception written into it, and it is the only reason you may ever be stationary inside one.

Box junctions. These have criss-cross yellow lines painted on the road (see “Road markings”). You MUST NOT enter the box until your exit road or lane is clear. However, you may enter the box and wait when you want to turn right, and are only stopped from doing so by oncoming traffic, or by other vehicles waiting to turn right. At signalled roundabouts you MUST NOT enter the box unless you can cross over it completely without stopping.

Read the exception carefully, because it is narrower than it looks. It permits waiting only when the sole thing stopping you is oncoming traffic or other right-turning vehicles. If the road you are turning into is blocked, the exception does not apply and the MUST NOT does. And at signalled roundabouts the exception disappears altogether.

You must not enter the box if your exit is not clear. If turning right at the junction, you may enter the box (behind other right-turning vehicles, if any) to wait for a gap in the oncoming traffic, but only if the right-turn exit is clear.

Turning right onto or off a dual carriageway

A dual carriageway right turn is two roads with a gap in between, and Rule 173 makes the whole decision turn on one measurement: whether the central reservation is deep enough to protect the full length of your vehicle. If it is, treat each half of the carriageway as a separate road and wait in the central reservation until there is a safe gap in the traffic on the second half. If it is too shallow for your vehicle, wait until you can cross both carriageways in one go.

Towing changes the answer to that question without changing the rule. So does the junction: the same gap that swallows a hatchback leaves a car and caravan sticking out into a live lane.

Cyclists, motorcyclists and pedestrians

The hierarchy of road users, introduced in January 2022, is written mostly around turning. Rule H3 names the manoeuvre directly.

You should not cut across cyclists, horse riders or horse drawn vehicles going ahead when you are turning into or out of a junction or changing direction or lane, just as you would not turn across the path of another motor vehicle. This applies whether they are using a cycle lane, a cycle track, or riding ahead on the road and you should give way to them.

Two more sit alongside it and are easy to miss on a right turn specifically.

• Rule 211 — the inside of the queue. “When turning right across a line of slow-moving or stationary traffic, look out for and give way to cyclists or motorcyclists on the inside of the traffic you are crossing.” A driver in the queue waving you through can see none of that.
• Rule 213 — cyclists in the middle of the lane. At road junctions and in slower-moving traffic, cyclists may ride in the centre of the lane rather than towards the side of the road, and the Code asks you to allow it so they can see and be seen. A cyclist holding the middle of the lane at a junction is following the Code, not obstructing you.

Pedestrians come first in the order. Rule H2 asks you to give way to pedestrians crossing or waiting to cross a road into which or from which you are turning; Rule 170 repeats it and adds that if they have started to cross, they have priority. The full set of 2022 changes is summarised in recent Highway Code changes.

Turning left, for contrast

Rules 182 and 183 are the mirror image, and reading them together is the fastest way to see what Rule 179 is actually asking for. Rule 182: use your mirrors and give a left-turn signal well before you turn, do not overtake just before you turn left, and watch out for traffic coming up on your left.

When turning keep as close to the left as is safe and practicable; give way to any vehicles using a bus lane, cycle lane, cycle track or tramway from either direction, including when they are passing slow moving or stationary vehicles on either side.

Close to the left for a left turn, just left of the middle for a right turn. Both rules put the car on the side of the road it is turning towards. Swinging left before turning right is the one shape neither rule describes. The examiner’s guidance names the left-turn version of the same error too — when turning left, the vehicle should be over to the left to avoid swinging out.

The equivalent lane-and-signal logic for a roundabout is a separate set of rules, 184 to 190, worked through in the roundabouts guide.

Common test questions and the answers

“Where exactly should the car be when I wait to turn right?”

Just left of the middle of the road, or in the space marked for traffic turning right, with a right-turn signal on and room left for other vehicles to pass on your left where the width allows. Mirrors first, then the signal, then the position — and all of it well before the junction rather than at it.

“Is it wrong to move left before turning right?”

Yes. Rule 179 puts you just left of the middle of the road and asks you to leave the left free for traffic that is not turning. Moving left contradicts both halves of the rule, makes your right signal misleading under Rule 103, and forces other traffic to wait behind you. Long vehicles are the exception the Code does allow for, because they may have to use the whole width of the road to make the turn.

“Two cars are facing each other and both want to turn right. Who goes first?”

Nothing in the Code ranks you. Rule 181 gives two methods — right side to right side, passing behind each other, which it calls generally the safer one, and left side to left side, passing in front of each other — and says road layout, markings or how the other vehicle is positioned can determine which is taken. Read the other driver’s line and match it.

“Why is right side to right side safer?”

Because you keep the other vehicle on your right and turn behind it, so you have a clear view of any approaching traffic while you complete the turn. Passing left side to left side puts the other car between you and the traffic coming towards you, and the Code specifically warns that cyclists and motorcyclists may be hidden in that blind spot.

“Can I wait on the hatched markings in the middle of the road?”

If the hatched area is bounded by a broken white line, yes — you should not enter unless it is necessary and you can see that it is safe, and waiting to turn right is the situation those markings are usually painted for. If it is marked with chevrons inside continuous white lines, you MUST NOT enter it except in an emergency.

“Can I pull into a yellow box junction to turn right?”

Only when oncoming traffic or other right-turning vehicles are the only thing stopping you, and your right-turn exit is clear. Otherwise the MUST NOT stands: do not enter the box until your exit road or lane is clear. At signalled roundabouts you MUST NOT enter unless you can cross the box completely without stopping.

“The lights went green but I can’t turn yet. Should I stay behind the line?”

No — moving forward to take up a position to turn right is exactly what Rule 176 allows on green, and it is what lets you complete the turn when the oncoming flow stops. What you MUST NOT do is move over the white line while the red light is showing.

“Do I still need to signal if I’m in a right-turn-only lane?”

Yes. Rule 179 lists the right-turn signal as a step in its own right, and Rule 103 asks for clear signals in plenty of time. The lane tells the driver behind where the lane goes; the indicator tells them what you are doing, and it is what pedestrians and cyclists near the junction are reading.

“An oncoming driver flashed me to turn. Can I go?”

Not on the flash. Rule 111 says never to assume that flashing headlights is a signal inviting you to proceed — use your own judgement and proceed carefully — and Rule 110 says the only message a flash is meant to send is that the vehicle is there. The driver waving you across cannot see the motorcyclist filtering past them.

Where this shows up in revision

Junction positioning, priority and give-way markings sit in the Rules of the road revision topic, and the same rules come back in Vulnerable road users the moment a cyclist appears at the junction. The multiple-choice questions are based on three books — The Highway Code, Know your traffic signs and Driving — the essential skills — and the first two are quoted the whole way down this page.

Northern Ireland has its own Highway Code, and the right-turn rules sit at the same numbers: 179 to 183, in the same order, with the same instructions on position, the safe gap, not cutting the corner and the two crossroads methods. The wording is not identical throughout — the Northern Ireland version of Rule 183 gives way to a bus lane, cycle lane or tramway, without the cycle track or the passing-stationary-vehicles clause the Great Britain rule adds — so read the local text on any point you are leaning on if you are testing with the DVA rather than DVSA.

Read Rules 103, 130, 143, 160, 170 to 183 and H2 to H3 in the Highway Code, work the 14 DVSA topics, check the wording in the glossary, see how right-turn positioning is marked on the practical in driving test faults, and sit a full mock theory test under the real timer. It is free to get started.
