While driving a vehicle stopping distance is calculated on the basis of driver’s thinking of distance, meaning that distance travelled by vehicle before the driver reacts to a hazard on the road and the braking distance, which is how long the vehicle takes to stop once the driver applies the brakes.
The overall stopping distance depends on thinking and the braking distance, and the braking distance further depends on various circumstances. It is these circumstances which affect the overall stopping distance:
- Thinking distance: Thinking distance depends on the driver and also the speed at which the vehicle is travelling. This can be increased by the following factors:
- Drivers tiredness and alertness
- The driver taking drink or drug (legal or illegal)
- Age of the driver-underaged and overaged driver may also have an increased thinking distance
- Lack of concentration of the driver-using mobile phone while driving
- The bad vision of the driver also leads to decrease reaction distance
- Braking Distance on Web-Dry Surface: Besides the speed at which the vehicle is travelling, braking distance gets affected and can increase by the below-mentioned points:
- The Vehicle’s weight.
- Brakes condition, in case of worn out discs/or pads longer time, is taken by vehicle to stop on wet weather.
- Wet or icy roads increases the braking distance.
- The condition of the road surface- On well-maintained roads with smooth surface less braking distance is there, whereas gravel, dirt and mud on the road will increase braking distance.
Further, the braking depends on the efficiency of your vehicle’s brakes. The following vehicle-related aspects are also to be considered when calculating the braking time and distance.
Braking with locked wheels
There is very less variability in stopping distance when braking with locked wheels, but however, on the wet roads, there is a much more dramatic reduction in friction which can result in your vehicle ploughing ahead on entry to a corner. A sudden locking of wheels gives you feeling of your having a vehicle with ASB system, as this type of braking with locked wheels is not recommended with ordinary braking systems.
Tires pressures and grip
With lower pressure in tires increases the size of the contact patch. So letting out some air from tires (of course as per the manufacturer’s guidelines) will help to have more grip in wet conditions. But all this can be done up to a certain point.
The depth of tread in tire and braking distance: Research has confirmed that tires with more tread depth have a greater ability to stop the vehicle at a small distance in the wet and icy roads. Extra 8 meters is required if the tread depth is 25% or less to stop the vehicle and 13 meters if the tread depth is less than 10%. Brakes work better if they are 100% working and if their slight variation in the efficiency level sudden braking leads to the brake failure all of a sudden in the emergency. So brakes should be always kept in the perfect working condition always.
