Braking distance. 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 ...
Stopping Sight Distance [:]...the distance required by the user, traveling at a given speed, to bring the vehicle or bicycle to a stop after an object ½-foot high on the road becomes visible. Stopping sight distance for motorists is measured from the driver's eyes, which are assumed to be 3½ feet above the pavement surface, to an object ½ ...
The two-second rule provides a simpler way of perceiving the distance. To estimate the time, a driver can wait until the rear end of the vehicle in front passes any distinct and fixed point on the roadway—e.g. a road sign, mailbox, line/crack/patch in the road. After the car ahead passes a given fixed point, the front of one's car should pass ...
In the US, for safety it is recommended that 3-4 seconds of following distance is maintained. [7] Extra time should be added for wet, rainy, slippery, foggy or other weather situations accordingly. [8] For heavy duty commercial vehicles it is recommended 4-6 seconds following distance for speeds under 30 mi/h (48 km/h), and 6-8 seconds ...
Regulatory signs. Regulatory signs give instructions to motorists, pedestrians, and cyclists. Signs including Stop, Yield, No Turns, No Trucks, No Parking, No Stopping, Minimum Speed, Right Turn Only, Do Not Enter, Weight Limit, and Speed Limit are considered regulatory signs.
A truck stop (known as a service station in the United Kingdom, [1] a travel center by major chains in the United States and a roadhouse in rural Australia) is a commercial facility which provides refueling, rest (parking), and often ready-made food and other services to motorists and truck drivers. Truck stops are usually located on or near a ...

Slip ratio is a means of calculating and expressing the slipping behavior of the wheel of an automobile.It is of fundamental importance in the field of vehicle dynamics, as it allows to understand the relationship between the deformation of the tire and the longitudinal forces (i.e. the forces responsible for forward acceleration and braking) acting upon it.
