What should a driver do if an oncoming vehicle drifts into their lane?

When an oncoming vehicle drifts into your lane, the recommended action is to steer right and brake gently if possible. This maneuver allows you to avoid a direct collision by providing a safer space to maneuver, as steering to the right may help you veer away from the oncoming vehicle's path. Gentle braking also helps to manage the speed of your vehicle smoothly, reducing the risk of losing control while you adjust your position on the roadway.

This response focuses on maintaining control of the vehicle and creating options for further action while ensuring safety. The choice to steer right aims to position your vehicle in a way that maximizes distance from the oncoming vehicle, which can be crucial in preventing an accident.

Alternative actions, like honking the horn and accelerating, could lead to a more dangerous situation, as acceleration might put you directly in the path of the other vehicle. Staying in your lane and hoping for the best ignores the imminent danger and does not provide any protective measure. Pulling over to the shoulder may not always be feasible or safe depending on the traffic conditions, and it doesn't directly address the immediate threat posed by the oncoming vehicle drifting into your lane. Hence, steering right and gently braking is the most effective and prudent response in this scenario.
