Question

all of the following are checked during an exterior pre-trip inspection except the rear-view mirror. tires. windshield. ground under the vehicle.

Explanation:

During an exterior pre - trip inspection, tires (for wear, pressure etc.), windshield (for cracks, clarity) and the ground under the vehicle (for leaks, debris) are typically checked. The rear - view mirror is usually an interior component (though some vehicles may have exterior rear - view mirrors in a different context, but generally in standard pre - trip exterior checks, it's not the main focus compared to the other three which are more exterior - oriented in terms of vehicle safety and functionality).

Answer:

rear - view mirror.
