# Accident — UK road sign

Warns drivers that a traffic incident has occurred ahead, requiring immediate caution and speed reduction.

The temporary 'accident' warning sign is set out by police or road operators following a collision or incident on the carriageway.

It warns approaching motorists to slow down immediately as stationary vehicles, debris, or emergency personnel may block the road.

## What this sign means

This sign features the word 'Accident' inside a red warning triangle, or on a temporary yellow backing board.

It indicates an active incident scene ahead with reduced lane capacity, stopped traffic, or emergency responders on foot.

- Temporary warning triangle with 'Accident' text
- Signifies obstruction or emergency emergency activity ahead
- Often deployed alongside flashing warning lights

## What to do when you see it

Reduce speed safely, do not rubberneck, and follow all instructions given by police or traffic officers at the scene.

- Check mirrors and slow down smoothly
- Keep full concentration on driving past the scene
- Be prepared to stop or merge as directed by emergency personnel

## How this sign is tested

Theory questions test knowledge of emergency procedures, hazard light usage, and responding to temporary police signage.

- Recognising temporary emergency warning signs
- Proper use of hazard warning lights when approaching queues
- Obeying signals given by police and traffic officers

## Common mistakes

Slowing down abruptly without checking mirrors, or distraction caused by gawking at the accident scene.

Your theory certificate lasts two years. Most learners who use it quickly do it with an intensive course — a block of hours with a DVSA approved instructor and a practical test at the end, instead of one lesson a week for months.
