• A. Angle of Approach
• B. Authority Having Jurisdiction
• C. Angle of Departure
• D. Certification Test

Departure angle describes rear clearance when a vehicle leaves an obstacle. It is the angle formed by level ground and a line drawn from the point where the rear tires touch the ground to the lowest projection at the rear of the apparatus. This is important for ensuring the rear overhang does not strike the ground or an obstacle as the vehicle departs from a crest or ramp. The front-side clearance is known as the angle of approach, which concerns climbing obstacles at the front, not the rear.
