- BRely entirely on the exterior side mirrors after adjusting them to a wider angle
- CTap the brakes while on the ramp to allow potential nearby vehicles to pass ahead
- DSound the horn to prompt any obscured drivers in adjacent lanes to move away

Look directly over the shoulder toward the adjacent lane to inspect areas outside mirror view
Turning the head to look over the shoulder directly observes the blind spot region adjacent to the vehicle, which cannot be seen through mirrors alone.
