Why should exterior mirrors on a passenger vehicle be checked and adjusted specifically for the vehicle's height and passenger door locations?

Pick an answer

1. Mirror adjustment has no relationship to passenger boarding or exiting safety
2. This adjustment matters only for vehicles with rear-engine configurations
3. Mirrors are relevant only for traffic behind the vehicle, never near the doors, since door safety is handled by the door's own sensor system
4. Proper adjustment helps the driver see passengers boarding or exiting near the doors clearly
