You should change lanes as directed by the sign. Here, the right-hand lane is closed but the
left-hand and centre lanes are available. Merging in turn is recommended when it's safe and traffic is going slowly; for example, at roadworks or a road traffic incident. When vehicles are travelling at speed, this isn't advisable and you should move into the appropriate lane in good time.

Even though there are no restrictions, make sure that you park where you won't cause an obstruction or endanger other road users.

Large vehicles throw up a lot of spray when it's wet. This makes it difficult for following drivers to see the road ahead. You'll be able to see more by dropping back further, out of the spray. This will also increase your separation distance, giving you more room to stop if you have to.

Dogs trained to help deaf people have a yellow or burgundy coat. If you see one, you should take extra care, as the pedestrian may not be aware of vehicles approaching.

Road humps are used to slow down traffic. They're found in places where there are often pedestrians, such as

A motorcycle is most stable when it's upright and moving in a straight line. This is the best time to brake. With independent front and rear brakes, both brakes should be used, with the front brake being applied just before the rear brake.

Staying back will increase your view of the road ahead. This will help you to see any hazards that might occur and give you more time to react.

If you intend to stop and rest, this sign allows you time to reduce speed and pull over safely.

The purpose of a CBT course is to teach you basic theory and practical skills before you ride on the road, on your own, for the first time. CBT courses can only be given by approved training bodies (ATBs).

As you approach a roundabout, look well ahead and check all signs. Decide which exit you wish to take and move into the correct position as you approach the roundabout, signalling as required.

Mandatory speed limit signs above all lanes including the hard shoulder, show that you are in an Active Traffic Management (ATM) area. In this case you can use the hard shoulder as a running lane. You must stay within the speed limit shown. Look out for any vehicles that may have broken down and be blocking the hard shoulder.

When it's foggy, use dipped headlights. This will help you see and be seen by other road users. If visibility is seriously reduced, consider using front and rear fog lights if you have them. Keep to a sensible speed and don't follow the vehicle in front too closely. If the road is wet and slippery, you'll need to allow twice the normal stopping distance.

These signals can be found at level crossings, some airfields, bridges and emergency access sites. You must stop if the red lights are flashing. At level crossings, if the lights continue to flash after a train has passed, continue to wait because another train is coming.

Be cautious and don't attempt to overtake. The driver may be unsure of the location of a junction and may turn suddenly.

You'll need to identify the sign in time, so that you can select an appropriate gear.

Vehicles over the weight shown on the sign may not use the bridge ahead. You must know the weight of your vehicle, including any load. With this knowledge you should plan your route in advance, so that you don't come to a bridge you can't cross. That way, you'll avoid delays and save time and fuel.

When you see this sign, you must give way to traffic from the opposite direction, regardless of the size of your vehicle.

The exit from a motorway is indicated by countdown markers. These are positioned 90 metres (100 yards) apart, the first being 270 metres (300 yards) from the start of the slip road. Move into the left-hand lane well before you reach the start of the slip road.

Before you can carry a pillion passenger, the law requires you to have a full licence for the category of motorcycle you're using.

Your visor protects your eyes from wind, rain, insects and road dirt. It's important to keep it clean and in good repair. A badly scratched visor can obscure your view and cause dazzle from the lights of oncoming vehicles.

Never attempt to change direction to the right without first checking your right-hand mirror and blind spot. A motorcyclist might not have seen your signal and could be hidden by other traffic. This observation should become a matter of routine.

This broken white line is a reminder to give way to traffic from the right at roundabouts. You can expect to find these at larger roundabouts.

Make yourself as visible as possible, from the side as well as from the front and rear. Having your headlights on, even in good daylight, can help make you more conspicuous.

Braking too hard will cause a skid. Release the brakes immediately to allow the wheels to turn, then reapply them as firmly as the road surface and conditions will allow.

Where you see this sign, the 20 mph restriction ends. Check all around for possible hazards and only increase your speed if it's safe to do so.

On a motorway, it's best to use a roadside emergency telephone so that the emergency services are able to find you easily. The location of the nearest telephone is shown by an arrow on marker posts at the edge of the hard shoulder. If you use a mobile, the operator will need to know your exact location. Before you call, find out the number on the nearest marker post. This number will identify your exact location.

When you pass your test on a motorcycle between 120 cc and 125 cc, you'll be issued with a full light motorcycle licence of category A1. You'll then be allowed to ride any motorcycle up to 125 cc and with a power output not exceeding 11 kW (14.6 bhp).

The studs between the carriageway and the hard shoulder are normally red. These change to green where there is a slip road. They will help you identify slip roads when visibility is poor or when it is dark.

Riding while under the influence of drink or drugs can invalidate your insurance. It also endangers yourself and others. The risk isn't worth taking.
