The same concept as the front approach angle, but measured from the rear tire to the lowest rear obstruction. What is this angle called?

• A. Angle of Departure
• B. Angle of Approach
• C. Proximity
• D. Accessibility

Answer: (A)

The concept here is clearance angles that show how well a vehicle can move away from obstacles. The front approach angle tells you how much obstacle the front of the vehicle can approach without the bumper or underbody hitting it. The rear counterpart is the departure angle, which measures from the rear tires to the lowest rear obstruction as you back away. A larger departure angle means better clearance when leaving or backing off an obstacle; a smaller one means the rear end is more likely to snag.

So, the term that matches “the same idea as the front approach angle, but measured from the rear” is the angle of departure. Proximity or accessibility aren’t standard terms used to describe this rear clearance, and they don’t capture the same idea of how steeply you can leave an obstacle without the rear bumper contacting the ground or an obstruction.
