Curb feeler mounted behind the front wheel of a 1950s Rambler American Curb feeler on a 1973 VAZ-2103 Ziguli (left) Curb feelers or curb finders are springs or wires installed on a vehicle that act as "whiskers" to alert drivers when they are at the right distance from the curb while parking. The devices are fitted low on the body, close to the ...
A parking space commonly contains a parking chock (also known as a parking curb, parking bumper, wheel stop, parking chock, curb stop, bumper block, [2] and turtarrier [citation needed]), a barrier which is used to prevent cars from pulling too far into the space and obstructing an adjacent parking space, curb, or sidewalk.
A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles from going past the end of a physical section of track. The design of the buffer stop is dependent, in part, on the kind of couplings that the railway uses, since the coupling gear is
The wall-to-wall turning circle is the minimum distance between two walls, both of which exceed the height of the vehicle, in which the vehicle can make a U-turn. The kerb-to-kerb turning circle is the minimum distance between two raised curbs, both of which are lower than the lowest body protrusions, in which the vehicle can make a U-turn.
Convex and flat buffer plates are easily recognizable on this Class E 18 Short buffers on a Panama canal mule. In many cases, the buffer on the left-hand side in the direction of travel was designed with a flat plate, and the one on the right with a curved plate, so that a flat plate and a curved plate always meet, thereby avoiding edge pressure.
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.

The most extreme example of this is where the wheel stops rotating altogether (wheel slide) while the train is still moving and can result in a “wheel flat” caused by the softer steel wheel being worn away by the harder steel rail. However, the wheelset does not need to lock up completely in order for damage to be caused.
