What should you do if an oncoming vehicle crosses into your lane?

If an oncoming vehicle crosses into your lane, the most appropriate response is to slow down, warn the other driver by flashing your headlights, and pull as far to the right as possible. This action helps to create more space and reduces the likelihood of a collision. By slowing down, you lower your speed, which gives both you and the other driver more time to react to the situation. Flashing your headlights serves as an alert to the oncoming driver that they are in your lane and may need to correct their course. Additionally, moving to the right maximizes your distance from the oncoming vehicle, further mitigating the risk of an accident.

In comparison, accelerating to avoid the situation could lead to a more dangerous outcome, as it decreases your ability to maneuver and increases the potential severity of a crash. Continuously blowing your horn might distract or surprise the other driver, but it does not help in steering or providing a way to safely avoid a collision. Finally, turning off your lights is unsafe, as it reduces your visibility and makes it harder for the other driver to see you, potentially exacerbating the situation. Therefore, the recommended action prioritizes safety and effective communication on the road.
