You are in a collision on a two-way road. You have a warning triangle with you. At what distance before the obstruction should you place the warning triangle?

A 45 metres (147 feet)

This is the minimum distance to place the triangle from the obstruction. If there’s a bend or hump in the road place it so that approaching traffic has plenty of time to react to the warning and slow down. You may also need to use your hazard warning lights, especially in poor visibility or at night.

If your vehicle breaks down, think first of all other road users and:

- get your vehicle off the road if possible

- warn other traffic by using your hazard warning lights if your vehicle is causing an obstruction

- help other road users see you by wearing light-coloured or fluorescent clothing in daylight and reflective clothing at night or in poor visibility

- put a warning triangle on the road at least 45 metres (147 feet) behind your broken-down vehicle on the same side of the road, or use other permitted warning devices if you have them. Always take great care when placing or retrieving them, but never use them on motorways

- if possible, keep your sidelights on if it is dark or visibility is poor

- do not stand (or let anybody else stand) between your vehicle and oncoming traffic

- at night or in poor visibility do not stand where you will prevent other road users seeing your lights

Helping my daughter with the theory side of the test. Only wish we’d found it earlier on! Even I’m learning/getting reminded of what things mean again!
