Developing Hazard Quiz: 10 UK Examples

Quick definition: a potential hazard is something you monitor. It becomes a developing hazard when it starts to make a safe driver change speed or direction. In the real hazard-perception test, click when that development begins.

SCENARIO 01

A car is parked at the kerb ahead. When does it become a developing hazard?

As soon as the parked car appearsIts right indicator flashes and it begins moving outOnly when it is fully in your lane

Answer: its indicator flashes and it begins moving out. A stationary car is potential. Movement towards your path means you may need to slow down or change position.

SCENARIO 02

A child is standing with an adult beside the pavement. What signals development?

The child is visibleYou are driving through a residential streetThe child turns away from the adult and steps towards the kerb

Answer: the child moves towards the kerb. The observable change increases the chance that your speed or direction must change.

SCENARIO 03

A van waits at a side road. When should you identify a developing hazard?

The front wheels start rolling towards the junction lineThe van is first visibleAfter it blocks your lane

Answer: when it starts rolling forward. Waiting is potential; movement towards your path is evidence that action may become necessary.

SCENARIO 04

You approach a cyclist with a parked delivery van ahead of them. What is the developing moment?

You first see the cyclistThe cyclist looks behind and begins moving away from the kerbYou have already drawn alongside

Answer: the cyclist checks behind and moves out. Their change in position may require you to slow down and give more room.

SCENARIO 05

Traffic ahead is flowing normally. Which change becomes a developing hazard?

Several vehicles are visibleThe road is busyBrake lights illuminate in sequence and the gap ahead closes

Answer: brake lights spread through the queue. The changing traffic state means you are likely to need to reduce speed.

SCENARIO 06

A pedestrian waits near a zebra crossing. When does the situation develop?

They turn towards the crossing and place a foot onto itThe crossing first enters viewYou have passed the crossing

Answer: they begin entering the crossing. Their movement is clear evidence that you must be prepared to stop.

SCENARIO 07

A bus is stopped ahead. Which event is the developing hazard?

The bus is largeA passenger walks from in front of the bus towards your laneYou notice the bus stop sign

Answer: a passenger emerges into your path. The bus was already a visibility risk; the pedestrian's movement creates the need for action.

SCENARIO 08

You follow a vehicle on a wet road. What turns the situation into a developing hazard?

The road is wetA vehicle is aheadThe vehicle brakes sharply while your following gap is closing

Answer: braking plus a closing gap. Wet conditions are a standing risk, but the changing distance creates an immediate need to slow.

SCENARIO 09

Roadworks narrow two lanes into one. When does another vehicle become a developing hazard?

It accelerates towards the same gap as youRoadwork signs are visibleCones are beside the road

Answer: it moves towards the same gap. The narrowing is potential; competing movement into limited space may force a speed or direction change.

SCENARIO 10

A horse rider travels ahead near the left edge. What indicates a developing hazard?

A horse rider is presentThe horse reacts to a noise and moves towards the centre of the laneThe road has no centre line

Answer: the horse moves towards the centre. The movement reduces safe space and means you should slow down and avoid passing.
