You may pass slower vehicles on their left while travelling along a one-way street. Be aware of drivers who may need to change lanes and may not expect faster traffic passing on their left.
The road will be very wet and spray from other vehicles will reduce your visibility. Tyre grip will also be reduced, increasing your stopping distance. You should at least double your separation distance to make sure you can stop safely in the space you've allowed.
Don't overtake if there’s a possibility of a road junction, bend or brow of a bridge or hill ahead. There are many hazards that are difficult to see in the dark. Only overtake if you’re certain that the road ahead is clear. Don’t take a chance.

The purpose of a box junction is to keep the junction clear by preventing vehicles from stopping in the path of crossing traffic.
You mustn't enter a box junction unless your exit is clear. However, you may enter the box and wait if you want to turn right and are only prevented from doing so by oncoming traffic.





This was the right answerRoad humps are used to slow down traffic. They're found in places where there are often pedestrians, such as
• shopping areas
• near schools
• residential areas.
Watch out for people close to the kerb or crossing the road.
Traffic-calming measures make the roads safer for vulnerable road users, such as cyclists, pedestrians and children. These can be designed as chicanes, road humps or other obstacles that encourage drivers and riders to slow down.
Reflective studs are used to help you in poor visibility. Different colours are used so that you’ll know which lane you're in. These are
• red on the left-hand edge of the carriageway
• white between lanes
• amber on the right-hand edge of the carriageway
• green between the carriageway and slip roads.

A rumble device consists of raised markings or strips, designed to give drivers an audible, visual and tactile warning. These devices are used in various locations, including in the line separating the hard shoulder and the left-hand lane on the motorway and on the approach to some hazards, to alert drivers to the need to slow down.
If you’re planning to make a journey when it’s foggy, listen to the weather reports. If visibility is very poor, avoid making unnecessary journeys. If you do travel, leave plenty of time – and if someone is waiting for you to arrive, let them know that your journey will take longer than normal. This will also take off any pressure you may feel to rush.
To prevent your headlights from dazzling the driver of the car in front, wait until you’ve passed them before switching to main beam.

Be patient and stay behind the car in front. You shouldn't normally overtake other vehicles in areas subject to traffic calming. If you overtake here, you may easily exceed the speed limit, defeating the purpose of the traffic-calming measures.

These lines may be painted on the road on the approach to a roundabout, a village or a particular hazard. The lines are raised and painted yellow, and their purpose is to make you aware of your speed. Reduce your speed in good time so that you avoid having to brake harshly over the last few metres before reaching the junction.
Take care when using single-track roads. It can be difficult to see around bends, because of hedges or fences, so expect to meet oncoming vehicles. Drive carefully and be ready to pull into or stop opposite a passing place, where you can pass each other safely.
Other drivers or riders may have to change course due to the size or characteristics of their vehicle. Understanding this will help you to anticipate their actions. Motorcyclists and cyclists will be checking the road ahead for uneven or slippery surfaces, especially in wet weather. They may need to move across their lane to avoid surface hazards such as potholes and drain covers.

A ford is a crossing over a stream that’s shallow enough to drive or ride through. After you’ve gone through a ford or deep puddle, your brakes will be wet and they won't work as well as usual. To dry them out, apply a light brake pressure while moving slowly. Don’t travel at normal speeds until you're sure your brakes are working properly again.
You won’t be able to see as far ahead in fog as you can on a clear day. You'll need to reduce your speed so that, if a hazard looms out of the fog, you have the time and space to take avoiding action.
Travelling in fog is hazardous. If you can, try to delay your journey until it has cleared.
The engine will need more power to pull the vehicle up the hill. When approaching a steep hill you should select a lower gear to help maintain your speed. You should do this without hesitation, so that you don’t lose too much speed before engaging the lower gear.
The draught caused by other vehicles – particularly those with high sides – could be strong enough to push you out of your lane. Be prepared for a sudden gust of wind as you overtake large vehicles. Keep both hands on the steering wheel to help you keep full control.
If you’re following another road user in fog, stay well back. The driver in front won’t be able to see hazards until they’re close and might need to brake suddenly. Also, the road surface is likely to be wet and could be slippery.
If you have to park your vehicle in foggy conditions, try to find a place to park off the road. If this isn’t possible, park on the road facing in the same direction as the traffic. Leave your parking lights switched on and make sure they're clean.
