Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.
d MT = braking distance, m (ft) V = design speed, km/h (mph) a = deceleration rate, m/s 2 (ft/s 2) Actual braking distances are affected by the vehicle type and condition, the incline of the road, the available traction, and numerous other factors. A deceleration rate of 3.4 m/s 2 (11.2 ft/s 2) is used to determine stopping sight distance. [6]
British Railway Class 90 infobox showing brake force Brake force to weight ratio of the Class 67 is higher than some other locomotives. In the case of railways, it is important that staff are aware of the brake force of a train so sufficient brake power will be available to bring the train to a halt within the required distance from a given speed.
The back of the concrete mixer truck carries a 'booster axle', which can be lowered to extend the wheelbase of a fully loaded truck to comply with regulations. [ 3 ] The formula was enacted as law to limit the weight-to-length ratio of a commercial motor vehicle (CMV). [ 4 ]
Brake fade can be a factor in any vehicle that utilizes a friction braking system including automobiles, trucks, motorcycles, airplanes, and bicycles. Brake fade is caused by a buildup of heat in the braking surfaces and the subsequent changes and reactions in the brake system components and can be experienced with both drum brakes and disc ...

The two-second rule is useful as it can be applied to any speed. Drivers can find it difficult to estimate the correct distance from the car in front, let alone remember the stopping distances that are required for a given speed, or to compute the equation on the fly. The two-second rule provides a simpler way of perceiving the distance.
The Mercedes-Benz Actros is a heavy-duty truck introduced by Mercedes-Benz at the 1996 Commercial Vehicle IAA in Hannover, Germany, as the replacement for the SK. It is normally used for long-distance haulage, heavy-duty distribution haulage, and construction haulage. It is powered by an inline-6 diesel engine with a turbocharger and ...
