Approach angle is the maximum angle of a ramp onto which a vehicle can climb from a horizontal plane without interference. [ 1 ] It is defined as the angle between the ground and the line drawn between the front tire and the lowest-hanging part of the vehicle at the front overhang .
β° = Breakover angle; C = Underside of chassis; W = Wheel; G = Ground; M = Midpoint of wheelbase Example of a vehicle at a significant breakover angle.. Breakover angle or rampover angle is the maximum possible supplementary angle (usually expressed in degrees) that a vehicle, with at least one forward wheel and one rear wheel, can drive over without the apex of that angle touching any point ...
A car ramp is a structure or device used to raise an automobile from the ground in order to access its undercarriage. [1] [2] An alternative method to using a jack or jack stands. Car ramps are simple to use and relatively inexpensive. Car ramps also offer safety for mechanics by providing vehicle stability during car maintenance and repairs. [3]
In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a lock or diameter of a tunnel in the case of watercraft.
The distance traveled up the ramp is then measured and is divided by the vehicle's wheelbase and finally multiplied by 1000 to give a final RTI score. [1] Most stock SUVs have RTI values from 400 to 550; [1] vehicles modified for off-road competition have the ability to exceed 1000. [2]

A road car usually has a ride height around 16–17 cm (6.3–6.7 in), while an SUV usually lies around 19–22 cm (7.5–8.7 in). Two well-known extremes are the Ferrari F40 with a 12.5 cm (4.9 in) ride height [1] and the Hummer H1 with a 40.64 cm (16.0 in) ride height.
Arrester bed: a gravel-filled ramp adjacent to the road that uses rolling resistance to stop the vehicle. [1] The required length of the bed depends on the mass and speed of the vehicle, the grade of the arrester bed, and the rolling resistance provided by the gravel. [2]
