You should know the speed limit for the type of road that you're on and the type of vehicle that you're driving or riding. Study your copy of The Highway Code.

The speed limit on a dual carriageway or motorway is 70 mph for cars and motorcycles, unless signs indicate otherwise. The speed limits for different types of vehicle are listed in The Highway Code.

There's a 30 mph speed limit where there are street lights unless signs show another limit.

The presence of street lights generally indicates that there's a 30 mph speed limit, unless signs tell you otherwise.

The red slash through the sign indicates that the restriction has ended. In this case, the restriction was a minimum speed limit of 30 mph.

Following a tractor can be frustrating, but never overtake if you’re unsure whether it’s safe. Ask yourself: 'Can I see far enough down the road to ensure that I can complete the manoeuvre safely?' It's better to be delayed for a minute or two than to take a chance that may cause a collision.

Long vehicles might have to take a slightly different position when approaching the roundabout or going around it. This is to stop the rear of the vehicle cutting in and mounting the kerb.

You mustn't stop where a clearway is in force, not even to pick up or set down passengers.

This sign indicates that there are waiting restrictions. It's normally accompanied by details of when the restrictions are in force. Details of most signs in common use are shown in The Highway Code. For more comprehensive coverage, see Know Your Traffic Signs.

Normally you should park on the left, but in a one-way street you may also park on the right-hand side of the road.

You should normally use the left-hand lane on any dual carriageway unless you're overtaking or turning right. 

Follow the lane you’re in and find somewhere safe to turn around and rejoin your route.

You can overtake other traffic on either side when traveling on a one-way street. Make full use of your mirrors and ensure it's clear all around before you attempt to overtake. Look for signs and road markings, and use the most suitable lane for your destination.

When going straight ahead at a roundabout, don’t signal as you approach it. Signal left just after passing the exit before the one you wish to take.

Always long vehicles might have to take a different course from normal at a roundabout so that the rear wheels don’t mount the kerb. If you’re following a long vehicle, stay well back and give it plenty of room.

Yellow box junctions are marked on the road to prevent the road becoming blocked. Don’t enter the box unless your exit road is clear. You may wait in the box if you want to turn right and your exit road is clear but oncoming traffic or other vehicles waiting to turn right are preventing you from making the turn.

The purpose of yellow box markings is to keep junctions clear of queuing traffic. You may only wait in the marked area when you’re turning right but you can’t complete the turn because of oncoming traffic or other traffic waiting to turn right.

You must obey signals to stop given by police and traffic officers, traffic wardens and school crossing patrols.

By standing on the pavement, the pedestrian is showing an intention to cross. By looking well ahead, you'll give yourself time to see the pedestrian, check your mirrors and respond safely.

Toucan crossings are similar to pelican crossings but there's no flashing amber phase. Cyclists share the crossing with pedestrians and are allowed to cycle across when the green cycle symbol is shown.

Don’t rev your engine or start to move off while they’re still crossing.

Except to pick up or set down passengers.

It is called 'turning offside to offside', this allows you a clear view of approaching traffic however, some junctions, usually controlled by traffic-light filters - are marked for vehicles to turn nearside to nearside.

Travel slowly and carefully near parked vehicles. Beware of • vehicles pulling out, especially bicycles and motorcycles • pedestrians, especially children, who may run out from between cars • drivers opening their doors.

Take care if you have to pass an obstruction, such as a parked vehicle, on your side of the road. Give way to oncoming traffic if there isn’t enough room for you both to continue safely.

Normally you should travel in the left-hand lane and only use the right-hand lane for overtaking or turning right. Move back into the left lane as soon as it’s safe but don’t cut in across the path of the vehicle you’ve just passed.

At unmarked crossroads nobody has priority. Practice good observation in all directions before you emerge or make a turn.

Don't park within 10 meters (32 feet) of a junction (unless in an authorised parking place). This is to allow drivers emerging from, or turning into, the junction a clear view of the road they're joining. It also allows them to see hazards such as pedestrians or cyclists at the junction.

It may be tempting to park where you shouldn’t while you run a quick errand. Careless parking is a selfish act and could endanger other road users.

If the lights at a level crossing keep flashing after a train has passed, you should continue to wait, because another train might be coming. Be patient and wait until the lights stop flashing.

This sign shows that you're leaving a controlled parking zone and those restrictions no longer apply.

Where there are extra hazards, such as at roadworks, it’s often necessary to slow traffic by imposing a lower speed limit. These speed limits aren’t advisory; they must be obeyed.

You may be difficult to see when you’re travelling at night, even on a well-lit road. If you use dipped headlights rather than sidelights, other road users should be able to see you more easily.

In this case, you should treat a dual carriageway as one road. Wait until the road is clear in both directions before emerging to turn right. If you try to treat it as two separate roads and wait in the middle, your vehicle will stick out and cause an obstruction that may lead to a collision.

Exceeding the speed limit is dangerous and can result in you receiving penalty points on your licence. Different speed limits apply if you're towing a trailer.

You must use parking lights when parking at night on a road or in a lay-by on a road with a speed limit greater than 30 mph. You must also park in the direction of the traffic flow and not close to a junction.

If there's a bend just before a level crossing, you may not be able to see the level-crossing barriers or waiting traffic. These signs give you an early warning that you may find these hazards just around the bend.

You'll find traffic officers on motorways and some primary routes in England and Wales. They work in partnership with the police, helping to keep traffic moving and helping to make your journey as safe as possible.

To go straight ahead at a roundabout, you should normally approach in the left-hand lane, but check the road markings. You won't normally need to signal as you approach, but signal before you leave the roundabout, as other road users need to know your intentions.

It's illegal to drive on or over a pavement, except to gain access to a property. If you need to cross a pavement, give priority to pedestrians.

When you're towing a trailer, a reduced speed limit also applies on dual carriageways and motorways. These lower speed limits apply to vehicles pulling all sorts of trailers, including caravans and horse boxes.

The speed limit for cars towing caravans or trailers on dual carriageways or motorways is 60 mph. Take care in windy weather, as a strong side wind can make a caravan or large trailer unstable.

Parking restrictions apply in a variety of places and situations. Make sure you know the rules and understand where and when restrictions apply. Controlled parking areas will be indicated by signs and road markings. Parking in the wrong place could cause an obstruction and danger to other traffic. It can also result in a fine.

While it's in operation, other vehicles must not use this part of the carriageway except to pick up or set down passengers. At other times, when the lane isn't in operation, you should still be aware that there may be cyclists using the lane. Give them plenty of room as you pass and allow for their movement from side to side, especially in windy weather or on a bumpy road.

Your road position can help other road users to anticipate your actions. Keep to the left as you approach a left turn and don't swing out into the centre of the road in order to make the turn easier. This could endanger oncoming traffic and may cause other road users to misunderstand your intentions.

At a level crossing, flashing red lights mean you must stop. If the train passes but the lights keep flashing, wait, another train may be coming.

Keep going; don’t stop on the crossing. If the warning sounds and the amber lights come on as you’re approaching the crossing, you must stop unless it's unsafe to do so. Red flashing lights together with the audible warning mean you must stop.

Don’t turn around in a busy street or reverse from a side road into a main road. Find a quiet side road and choose a place to turn around where you won’t obstruct an entrance or exit. Look out for pedestrians and cyclists as well as other traffic.

You may remove your seat belt while you're carrying out a manoeuvre that includes reversing. However, you must remember to put it back on again before you resume driving.

You mustn't reverse further than is necessary. You may decide to turn your vehicle around by reversing into an opening or side road. When you reverse, always look all around you and watch for pedestrians. Don’t reverse from a side road into a main road.

A small child could be hidden directly behind you, so, if you can't see all around your vehicle, get out and have a look. You could also ask someone reliable outside the vehicle to guide you.

Don’t reverse into a main road from a side road because your view will be restricted. The main road is likely to be busy and the traffic on it moving quickly.

You can wait in the box junction as long as your exit is clear.

Always check in all directions before reversing. Keep a good lookout throughout the manoeuvre and remember that the front will swing out as you reverse into the side road. Act on what you see and wait if necessary.

If you have a garage, use it. Your vehicle is less likely to be a victim of car crime if it's in a garage. Also, in winter, the windows will be kept free from ice and snow.

Urban clearways have their times of operation clearly signed. You may only stop to pick up or set down passengers.

It's illegal to park in a space reserved for disabled drivers unless you're permitted to do so. These spaces are provided for people with limited mobility, who may need extra space to get in and out of their vehicle.

Pull into the nearest passing place on the left if you meet another vehicle on a narrow road. If the nearest passing place is on the right, wait opposite it.

Dip your headlights as soon as the driver passes you and drop back so that the dipped beam falls short of the vehicle in front.

Some bus lanes operate only during peak hours and other vehicles may use them outside these hours. Make sure you check the sign for the hours of operation before driving in a bus lane.

Your brake lights will give an indication to traffic behind that you're slowing down. Good anticipation will allow you time to check your mirrors before slowing.

Make sure you carry out the manoeuvre without causing a hazard to other vehicles.

When you're parking at night, park in a well-lit area. This can help deter criminals from targeting your vehicle.

Keep a lookout for traffic signs. If you’re directed to change lanes, do so in good time. Don’t push your way into traffic in another lane • try to gain advantage by delaying changing lanes.

Cycle lanes are marked with either a solid or a broken white line. If the line is solid, you should check the times of operation shown on the signs, and not drive or park in the lane during those times. If the line is broken, you shouldn't drive or park in the lane unless it's unavoidable.

Don’t park in a space reserved for disabled people unless you or your passenger are a Blue Badge holder. The badge must be displayed on the dashboard or fascia panel, where it can be clearly read through the front windscreen.

You must stop your vehicle when signalled to do so by a • police, DVSA or traffic officer • traffic warden • school crossing patrol • red traffic light. You must also stop if you're involved in an incident that causes damage or injury to any other person, vehicle, animal or property.
