When an oncoming driver drifts into your lane, moving to the right is the best course of action. This maneuver provides a safe escape route and helps to avoid a potential collision. By steering to the right, you can often access the shoulder of the road or create more distance between yourself and the encroaching vehicle, which may help prevent a head-on collision—a particularly dangerous type of accident.

Staying in your lane may seem like a stabile option, but it significantly increases the risk of an accident if the other driver continues into your lane. Likewise, moving to the left would put you closer to oncoming traffic, which is not advisable in this scenario. Slamming on the brakes can lead to unpredictable results, such as being rear-ended by vehicles behind you or losing control of your vehicle, especially if road conditions are poor. Thus, moving to the right is a proactive and safer choice in response to an imminent hazard.
