In manual transmission vehicles, the parking brake is engaged to help keep the vehicle stationary while parked, especially if parked on an incline. [2] [3]While automatic transmission vehicles have a "Park" gear that immobilizes the transmission, it is still recommended to use the parking brake, as the parking pawl in the gearbox could fail due to stress or another vehicle striking the car ...
d = run Δh = rise l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent.
On the uphill sections, the vehicle delivers more power to the wheels to overcome gravity, thereby, increasing the shearing force of the studs against the pavement, thus resulting in an increased cutting action. Ruts are also deeper at the entry to and exit from intersections and corners, due to deceleration (braking) and acceleration.
A hill-holder is a motor vehicle device that holds the brake until the clutch is at the friction point, making it easier for a stationary vehicle to start uphill. By holding the brake in position while the vehicle is put into gear, it prevents rollback.
Climbing lane in Hungary; centre of image - right hand lane. A climbing lane, crawler lane (UK [1]), or truck lane, is an additional roadway lane that allows heavy or underpowered vehicles to ascend a steep grade without slowing other traffic.

Parallel parking is a method of parking a vehicle parallel to the road, in line with other parked vehicles. Parallel parking usually requires initially driving slightly past the parking space , parallel to the parked vehicle in front of that space, keeping a safe distance, then followed by reversing into that space.
An overrun brake (called a surge brake when invented) is a brake system commonly used on small trailers, where the motion of the trailer with respect to the towing vehicle is used to actuate the brake.
