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.
This flag is shown if the driver or pit crew violates a rule (e.g., speeding through the pits), if the vehicle has sufficient mechanical damage that it is a hazard to other drivers, if the vehicle cannot maintain the minimum required speed (varies by track; typically disclosed in the pre-race drivers' meeting), or if a driver has been driving ...
Right before a wheel locks up, it will experience a rapid deceleration. If left unchecked, the wheel would stop much more quickly than any car could. It might take a car two to four seconds to stop from 60 mph (96.6 km/h) under ideal conditions, but a wheel that locks up could stop spinning in less than a second.
A runaway truck ramp on the A7 in Germany. A runaway truck ramp, runaway truck lane, escape lane, safety ramp, emergency escape ramp, or truck arrester bed is a traffic device that enables vehicles which are having braking problems to stop safely.
A wheel clamp, also known as wheel boot, parking boot, or Denver boot, [1] [2] is a device that is designed to prevent motor vehicles from being moved. In its most common form, it consists of a clamp that surrounds a vehicle wheel, designed to prevent removal of both itself and the wheel.
The Mine Safety and Health Administration (MSHA) has established standards that wheel chocks are used when a vehicle is parked on a grade, and Occupational Safety and Health Administration (OSHA) has guidelines that require wheel chocks during loading or unloading of a heavy truck. The wheel chock was invented by Canadian engineer Robert B ...
The driver of the No. 1 Chevrolet used a move straight out of a video game to pass five cars in the final corner, securing him a spot in the final playoff race. Ross Chastain’s Crazy Wall-Ride ...
The design sight distance allows a below-average driver to stop in time to avoid a collision in most cases. Driver perception/reaction distance is calculated by: d PRT = 0.278 Vt (metric) d PRT = 1.47 Vt (US customary) Where: d PRT = driver perception-reaction distance, m (ft) V = design speed, km/h (mph) t = brake reaction time, in seconds
