Under the regulations, you must not enter a yellow box junction unless your exit is clear. However, you can enter the box and wait if you want to turn right and are only blocked by oncoming traffic or other vehicles also waiting to turn right.

A last check in the offside mirror and blind spot will allow you sight of any cyclist or motorcyclist overtaking as you wait to turn.

Drive extremely carefully when the roads are icy. When travelling on ice, tyres make virtually no noise and the steering feels light and unresponsive. In icy conditions be very gentle when braking, accelerating and steering.

You will have additional hazards to deal with at night. Visibility may be very limited and the lights of oncoming vehicles can often dazzle you. When this happens don’t close your eyes, swerve or flash your headlights, as this will also distract other drivers. It may help to focus on the left kerb, verge or lane line.

Pull over in a place where the ambulance can pass safely. Check that there are no bollards or obstructions in the road that will prevent it from doing so.

Use the full beam headlights only when you can be sure that you won’t dazzle other road users.

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 surface spray reduces visibility switch on your dipped headlights. This will help other road users to see you.

The crossroads sign indicates an intersection ahead. You should prepare to give way to other vehicles. The sign warns of potential traffic from different directions. It helps you anticipate the need to stop or slow down.

If your vehicle is fitted with drum brakes they can get hot and lose efficiency. This happens when they’re used continually, such as on a long, steep, downhill stretch of road. Using a lower gear will assist the braking and help prevent the vehicle gaining momentum.

You should give way to traffic already on the motorway. Where possible they may move over to let you in but don’t force your way into the traffic stream. The traffic may be travelling at high speed so you should match your speed to fit in.

These signs only apply to trams. They are directed at tram drivers but you should know their meaning so that you’re aware of the priorities and are able to anticipate the actions of the driver.

The restraint should be adjusted so that it gives maximum protection to the head and neck. This will help in the event of a rear- end collision.

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.

To prevent your lights from dazzling the driver of the car in front, wait until you’ve overtaken before switching to full beam.

If you’re waiting to emerge from a side road watch out for motorcycles: they’re small and can be difficult to see. Be especially careful if there are parked vehicles restricting your view, there might be a motorcycle approaching. IF YOU DON’T KNOW, DON’T GO.

You should carry out frequent checks on all fluid levels but particularly brake fluid. As the brake pads or shoes wear down the brake fluid level will drop. If it drops below the minimum mark on the fluid reservoir, air could enter the hydraulic system and lead to a loss of braking efficiency or complete brake failure.

You'll see this sign if there has been an incident ahead and the motorway is closed. You must obey the sign. Make sure that you prepare to leave in good time. Don't cause drivers to take avoiding action by cutting in at the last moment.

If you see a red cross above your lane it means that there is an obstruction ahead. You will have to move into one of the lanes which is showing the green light. If all the lanes are showing a red cross, then you must stop.

These signs are often seen in one-way streets that have more than one lane. When you see this sign, use the route that's the most convenient and doesn't require a late change of direction.

Rear fog lights shine brighter than normal rear lights so that they show up in reduced visibility. When the weather is clear they could dazzle the driver behind, so switch them off.

Traffic on motorways usually travels faster than on other roads. You need to be looking further ahead to give yourself more time to react to any hazard that may develop.

If you see a vehicle with a flashing green beacon approaching, allow it to pass when you can do so safely. Be aware that someone’s life could depend on the driver making good progress through traffic.

You should be constantly scanning the road for clues about what is going to happen next. Check your mirrors regularly, particularly as soon as you spot a hazard. What is happening behind may affect your response to hazards ahead.

Sometimes you may not realise that someone is in shock. The signs to look for are rapid pulse, sweating, pale grey skin and rapid shallow breathing.

These lines are often found on the approach to a roundabout or a dangerous junction. They give you extra warning to adjust your speed. Look well ahead and do this in good time.

Coasting is when you allow the vehicle to freewheel in neutral or with the clutch pedal depressed. Doing this gives you less control over the vehicle. It's especially not to let your vehicle coast when approaching hazards such as junctions and bends and when travelling downhill.

Drivers are instructed that the left turn is prohibited for vehicles.
