Hazard Perception Flashcards

What clue might suggest a vehicle is about to pull out from a side road?

Answer: The vehicle's wheels are turned towards you, or you can see the driver looking your way

Turned wheels indicate the driver intends to move. If you can see the driver looking in your direction, they may be judging a gap in traffic. Other clues include exhaust smoke (engine running), brake lights releasing, or the vehicle creeping forward.

What is the danger of 'target fixation' while driving?

Answer: Staring at a hazard instead of looking where you want to steer, increasing the chance of hitting it

Target fixation occurs when you focus on an object you want to avoid (like a pothole or oncoming vehicle) and inadvertently steer towards it. Instead, look where you want to go — your hands will follow your eyes. This is especially important in emergency situations.

When emerging from a junction, why should you look twice in each direction?

Answer: Because a fast-moving vehicle or cyclist may not have been visible on your first look

A second look catches things you may have missed: a fast-approaching vehicle, a cyclist hidden by a pillar, or a pedestrian who has just stepped into the road. The situation changes in the seconds between looks, so a second check provides crucial updated information.

What hazard perception risk do large vehicles such as lorries pose at roundabouts?

Answer: They may need to straddle lanes to negotiate the roundabout, and they have larger blind spots

Large vehicles need more room to turn and may need to occupy more than one lane on a roundabout. Their size creates larger blind spots, meaning the driver may not see you. Give them plenty of room and do not try to squeeze past. Watch their indicators carefully.

When driving in rain, what specific hazard does standing water on the road create?

Answer: Aquaplaning — where your tyres lose contact with the road surface and you lose steering control

Aquaplaning occurs when a film of water builds up between your tyres and the road surface, causing a loss of grip and steering control. It is more likely at higher speeds and with worn tyres. If you feel light steering, ease off the accelerator — do not brake sharply.

What should you be aware of when following a bus that is slowing down at a bus stop?

Answer: Passengers may step into the road after leaving the bus, and the bus may pull out suddenly

When a bus stops, passengers may alight and cross the road, sometimes from in front of the bus where you cannot see them. The bus may then signal and pull out — and you should give way to it. Scan both sides and be prepared to stop.
