Question:

When may you wait in a box junction?

A When oncoming traffic prevents you turning right

explanation

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

How can you use the engine of your vehicle to control your speed?

By changing to a lower gear

You should brake and slow down before selecting a lower gear. The gear can then be used to keep the speed low and help you control the vehicle. This is particularly helpful on long downhill stretches, where brake fade can occur if the brakes overheat.

Why could keeping the clutch down or selecting neutral for long periods of time be dangerous?

You will have less steering and braking control

Letting your vehicle roll or coast in neutral reduces your control over steering and braking. This can be dangerous on downhill slopes where your vehicle could pick up speed very quickly.

You see these markings on the road. Why are they there?*

To make you aware of your speed

These lines may be painted on the road on the approach to a roundabout, 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.

You see a vehicle coming towards you on a single-track road. You should

stop at a passing place

You must take extra care when on single track roads. You may not be able to see around bends due to high hedges or fences. Proceed with caution and expect to meet oncoming vehicles around the next bend. If you do, pull into or opposite a passing place.

A rumble device is designed to

alert you to a hazard

A rumble device consists of raised markings or strips across the road. It gives drivers an audible, visual and tactile warning. They are found along the hard shoulder on the motorway and approaching some hazards to alert drivers of the need to slow down.

You are travelling in very heavy rain. Your overall stopping distance is likely to be

doubled

As well as visibility being reduced, the road will be extremely wet. This will reduce the grip the tyres have on the road and increase the distance it takes to stop. Double your separation distance.

Front fog lights should be used

when visibility is reduced to 100 metres (328 feet)

When visibility is seriously reduced, switch on your fog lights if you have them fitted. It is essential not only that you can see ahead, but also that other road users are able to see you.
