What term describes the angle from the front tire's ground contact to any projection ahead of the front axle?

• A. Approach angle
• B. Clearance angle
• C. Departure angle
• D. Swing angle

Answer: (A)

Approach angle is the measure of how steep an obstacle in front of the vehicle can be approached without the front end contacting it. It’s defined by the angle formed between the ground and a line drawn from the front tire’s contact point to a projection ahead of the front axle. This description matches exactly what the question asks about. In practice, a larger approach angle means the vehicle can ascend steeper obstacles without the bumper or undercarriage hitting, which is especially important for off-road and emergency-response vehicles. The other terms describe different clearances (rear clearance, underside clearance) or are not standard for this context, so they don’t fit the description.
