What is involved with braking?
1. Spot the hazard. 2. Thinking Distance – the time taken
between seeing the hazard and hitting the brakes.
3. Braking Distance – the time taken between applying the brakes and the car stopping.

Thinking DistanceThis can be affected by:
1. How fast you are going – the faster you are travelling, the further you will travel.
2. How dopey you are – this can be as a result of being tired, under the influence of drugs, old age and/or careless attitude.

Braking DistanceThis can be affected by:
1. How fast you are travelling – the faster you travel, the further it takes to stop.
2. How heavily loaded you are – with the same brakes a heavily laden vehicle takes longer to stop.
3. How good your brakes are – you must keep them well maintained.
4. How good the grip is – this depends on the road surface, weather conditions and tyres.

• Bad visibility – fog, bright oncoming lights, heavy rain, snow etc.
• Distractions from passengers, mobile phones, music, etc.

Repeat trying to get your stop watch to stop on 1 minute, then 2 and 3 minutes.
Think about:
