What action must you take to avoid a head-on collision with an oncoming vehicle?

To avoid a head-on collision with an oncoming vehicle, steering right toward the shoulder or curb-line is the safest and most effective action to take. This maneuver creates space between your vehicle and the oncoming vehicle, reducing the chances of a collision. By moving to the right side of the roadway, you are more likely to find an escape route, which can be crucial in a tense and quickly developing situation.

In addition, this action enables you to maintain control of your vehicle while navigating away from danger, rather than moving into oncoming traffic where the risk of an accident increases significantly. The shoulder is intended for emergencies, and while ideally, you want to stay on the road, steering right opens up options for avoiding the oncoming vehicle safely.

Other options, like stopping to wait for the vehicle to pass or honking your horn, may not effectively prevent a collision, especially if the oncoming vehicle cannot stop in time. Steering left into oncoming traffic significantly increases the risk of a head-on crash and is not a viable option for safety. Slowing down may be helpful, but without taking evasive action, it may not prevent the collision. Thus, maneuvering right is the best course of action to avoid a collision.
