What should a driver do upon sensing a potential collision with an oncoming vehicle?

When a driver senses a potential collision with an oncoming vehicle, sounding the horn serves as a critical warning signal. This action aims to alert the other driver to the imminent danger, potentially prompting them to take corrective measures to avoid a collision. In such tense situations, communication can be vital, and using the horn is an effective way to convey urgency.

Taking evasive action is also essential; this could involve steering away from the oncoming vehicle if there's room to do so safely. The combined effort of attracting attention and making an evasive maneuver can greatly reduce the likelihood of a collision occurring. This approach prioritizes safety and situational awareness, which are fundamental principles in driving.

Driving defensively by attempting to alert other road users while also considering available options to maneuver can prevent accidents and contribute to overall road safety. In contrast, accelerating or braking sharply could exacerbate the situation, potentially leading to more severe consequences, while pulling over may not always be feasible depending on the circumstances and layout of the road.
