How are stopping distances affected by wet conditions?
In wet weather, stopping distances will be at least double those required for stopping on dry roads (see rule 126). This is because your tyres have less grip on the road. In wet weather: you should keep well back from the vehicle in front – this will increase your ability to see and plan ahead.
What is the stopping distance in the wet?
Research suggests braking distances can be doubled in wet conditions – and multiplied by 10 on snow or ice. That means, in the snow, it could take you further than the length of seven football pitches to stop from 70mph.
What is the stopping distance in dry weather?
This is a good rule of thumb for car stopping distances in dry conditions, but if it’s wet you should double the gap to 4 seconds. Remember that it’s only a rough guide and there’s a margin for error. At lower speeds, 2 seconds will see you further back than the Highway Code stopping distances.
What are two important things about stopping distance?
These first 2 components of stopping distance are human factors and as such can be effected by tiredness, alcohol, fatigue and concentration levels. A perception and reaction time of 3 or 4 seconds is possible. 4 seconds at 100 km/hr means the car travels 110 metres before the brakes are applied.
How much does heavy rain affect stopping distance?
How is this likely to affect your overall stopping distance? Explanation: The road will be very wet and spray from other vehicles will reduce your visibility. Tyre grip will also be reduced, increasing your stopping distance. You should at least double your separation distance.
How do you find the stopping distance?
Stopping distance = thinking distance + braking distance Thinking distance is the distance that you travel in your car from the point of detecting a hazard to the point of beginning to brake or swerve.
What is the meaning of stopping distance?
Definition of stopping distance : the distance that a driver needs in order to safely bring a vehicle to a complete stop.
What are 5 factors that affect stopping distance?

- Speed. Your stopping distance is actually made up of two factors – thinking distance and braking distance.
- Brakes.
- Tyre Pressure.
- Tyre Wear.
- Tyre Quality.
- Road Conditions.
- View of the Road.
- Distractions.
What are the three factors that affect stopping distance?
Stopping distance consists of three factors: Driver’s reaction time + Brake lag + Braking distance.
