307 Highway Code Rules

Highway Code Rule 161

Mirrors. All mirrors should be used effectively throughout your journey. You should

  • use your mirrors frequently so that you always know what is behind and to each side of you
  • use them in good time before you signal or change direction or speed
  • be aware that mirrors do not cover all areas and there will be blind spots. You will need to look round and check.

Remember: Mirrors – Signal – Manoeuvre

Section: Using the road (rules 159 to 203)
Subsection: General rules (rules 159 to 161)

Highway Code Rule 162

Before overtaking you should make sure

  • the road is sufficiently clear ahead
  • road users are not beginning to overtake you
  • there is a suitable gap in front of the road user you plan to overtake.
Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 163

Overtake only when it is safe and legal to do so. You should

  • not get too close to the vehicle you intend to overtake
  • use your mirrors, signal when it is safe to do so, take a quick sideways glance if necessary into the blind spot area and then start to move out
  • not assume that you can simply follow a vehicle ahead which is overtaking; there may only be enough room for one vehicle
  • move quickly past the vehicle you are overtaking, once you have started to overtake. Allow plenty of room. Move back to the left as soon as you can but do not cut in
  • take extra care at night and in poor visibility when it is harder to judge speed and distance
  • give way to oncoming vehicles before passing parked vehicles or other obstructions on your side of the road
  • only overtake on the left if the vehicle in front is signalling to turn right, and there is room to do so
  • stay in your lane if traffic is moving slowly in queues. If the queue on your right is moving more slowly than you are, you may pass on the left. Cyclists may pass slower moving or stationary traffic on their right or left and should proceed with caution as the driver may not be able to see you. Be careful about doing so, particularly on the approach to junctions, and especially when deciding whether it is safe to pass lorries or other large vehicles.
  • give motorcyclists, cyclists and horse riders and horse drawn vehicles at least as much room as you would when overtaking a car (see Rules 211 to 215).

As a guide:

  • leave at least 1.5 metres when overtaking cyclists at speeds of up to 30mph, and give them more space when overtaking at higher speeds
  • pass horse riders and horse-drawn vehicles at speeds under 10 mph and allow at least 2 metres of space
  • allow at least 2 metres of space and keep to a low speed when passing a pedestrian who is walking in the road (for example, where there is no pavement)
  • take extra care and give more space when overtaking motorcyclists, cyclists, horse riders, horse drawn vehicles and pedestrians in bad weather (including high winds) and at night
  • you should wait behind the motorcyclist, cyclist, horse rider, horse drawn vehicle or pedestrian and not overtake if it is unsafe or not possible to meet these clearances.

Remember: Mirrors – Signal – Manoeuvre

Rule 163: Give vulnerable road users at least as much space as you would a car
Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 164

Large vehicles. Overtaking these is more difficult. You should

  • drop back. This will increase your ability to see ahead and should allow the driver of the large vehicle to see you in their mirrors. Getting too close to large vehicles, including agricultural vehicles such as a tractor with a trailer or other fixed equipment, will obscure your view of the road ahead and there may be another slow-moving vehicle in front
  • make sure that you have enough room to complete your overtaking manoeuvre before committing yourself. It takes longer to pass a large vehicle. If in doubt do not overtake
  • not assume you can follow a vehicle ahead which is overtaking a long vehicle. If a problem develops, they may abort overtaking and pull back in
Rule 164: Do not cut in too quickly
Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 165

You MUST NOT overtake

  • if you would have to cross or straddle double white lines with a solid line nearest to you (but see Rule 129)
  • if you would have to enter an area designed to divide traffic, if it is surrounded by a solid white line
  • the nearest vehicle to a pedestrian crossing, especially when it has stopped to let pedestrians cross
  • if you would have to enter a lane reserved for buses, trams or cycles during its hours of operation
  • after a ‘No Overtaking’ sign and until you pass a sign cancelling the restriction.

Laws

Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 166

DO NOT overtake if there is any doubt, or where you cannot see far enough ahead to be sure it is safe. For example, when you are approaching

  • a corner or bend
  • a hump bridge
  • the brow of a hill.
Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 167

DO NOT overtake where you might come into conflict with other road users. For example

  • approaching or at a road junction on either side of the road
  • where the road narrows
  • when approaching a school crossing patrol
  • on the approach to crossing facilities
  • where a vehicle ahead is slowing to stop for a pedestrian that is crossing from a pedestrian island (see Rule 165)
  • between the kerb and a bus or tram when it is at a stop
  • where traffic is queuing at junctions or road works
  • when you would force another road user to swerve or slow down
  • at a level crossing
  • when a road user is indicating right, even if you believe the signal should have been cancelled. Do not take a risk; wait for the signal to be cancelled
  • stay behind if you are following a cyclist approaching a roundabout or junction, and you intend to turn left. Do not cut across cyclists going ahead, including those using cycle lanes and cycle tracks (see Rule H3)
  • stay behind if you are following a horse rider or horse drawn vehicle approaching a roundabout or junction, and you intend to turn left. Do not cut across a horse rider or horse drawn vehicle going ahead
  • when a tram is standing at a kerbside tram stop and there is no clearly marked passing lane for other traffic.
Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 168

Being overtaken. If a driver is trying to overtake you, maintain a steady course and speed, slowing down if necessary to let the vehicle pass. Never obstruct drivers who wish to pass. Speeding up or driving unpredictably while someone is overtaking you is dangerous. Drop back to maintain a two-second gap if someone overtakes and pulls into the gap in front of you.

Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 169

Do not hold up a long queue of traffic, especially if you are driving a large or slow-moving vehicle. Check your mirrors frequently, and if necessary, pull in where it is safe and let traffic pass.

Section: Using the road (rules 159 to 203)
Subsection: Overtaking (rules 162 to 169)

Highway Code Rule 170

Take extra care at junctions. You should

  • watch out for cyclists, motorcyclists and pedestrians including powered wheelchairs/mobility scooter users as they are not always easy to see. Be aware that they may not have seen or heard you if you are approaching from behind
  • give way to for pedestrians crossing or waiting to cross a road into which or from which you are turning. If they have started to cross they have priority, so give way (see Rule H2)
  • remain behind cyclists, horse riders, horse drawn vehicles and motorcyclists at junctions even if they are waiting to turn and are positioned close to the kerb
  • watch out for long vehicles which may be turning at a junction ahead; they may have to use the whole width of the road to make the turn (see Rule 221)
  • watch out for horse riders who may take a different line on the road from that which you would expect
  • not assume, when waiting at a junction, that a vehicle coming from the right and signalling left will actually turn. Wait and make sure
  • look all around before emerging. Do not cross or join a road until there is a gap large enough for you to do so safely.

 

Rule 170: Give way to pedestrians who have started to cross
Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 171

You MUST stop behind the line at a junction with a ‘Stop’ sign and a solid white line across the road. Wait for a safe gap in the traffic before you move off.

Laws

Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 172

The approach to a junction may have a ‘Give Way’ sign or a triangle marked on the road. You MUST give way to traffic on the main road when emerging from a junction with broken white lines across the road.

Laws

Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 173

Dual carriageways. When crossing or turning right, first assess whether the central reservation is deep enough to protect the full length of your vehicle.

  • If it is, then you should treat each half of the carriageway as a separate road. Wait in the central reservation until there is a safe gap in the traffic on the second half of the road.
  • If the central reservation is too shallow for the length of your vehicle, wait until you can cross both carriageways in one go.
Rule 173: Assess your vehicle’s length and do not obstruct traffic
Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 174

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.

Law

Rule 174: Enter a box junction only if your exit road is clear
Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 175

You MUST stop behind the white ‘Stop’ line across your side of the road unless the light is green. If the amber light appears you may go on only if you have already crossed the stop line or are so close to it that to stop might cause a collision.

Laws

Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 176

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. If the traffic lights are not working, treat the situation as you would an unmarked junction and proceed with great care.

Laws

Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 177

Green filter arrow. This indicates a filter lane only. Do not enter that lane unless you want to go in the direction of the arrow. You may proceed in the direction of the green arrow when it, or the full green light shows. Give other traffic, especially cyclists, time and room to move into the correct lane.

Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 178

Advanced stop lines. Some signal-controlled junctions have advanced stop lines to allow cyclists to be positioned ahead of other traffic. Motorists, including motorcyclists, MUST stop at the first white line reached if the lights are amber or red and should avoid blocking the way or encroaching on the marked area at other times, e.g. if the junction ahead is blocked. If your vehicle has proceeded over the first white line at the time that the signal goes red, you should stop as soon as possible and MUST stop at the second white line. Allow cyclists, including any moving or waiting alongside you, enough time and space to move off when the green signal shows.

Drivers of large vehicles should stop sufficiently far behind the first white line so that they can see the whole area where cyclists may be waiting, allowing for any blind spot in front of the vehicle.

Laws

Rule 178: Do not unnecessarily encroach on the cyclists waiting area
Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 179

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.
Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)

Highway Code Rule 180

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.

Remember: Mirrors – Signal – Manoeuvre

Rule 180: Position your vehicle correctly to avoid obstructing traffic
Section: Using the road (rules 159 to 203)
Subsection: Road junctions (rules 170 to 183)
