Approach and departure angles

Approach angle is the maximum angle of a ramp onto which a vehicle can climb from a horizontal plane without interference. 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. Departure angle is its counterpart at the rear of the vehicle – the maximum ramp angle from which the car can descend without damage. Approach and departure angles are also referred to as ramp angles.
