What must drivers do on a road without a centerline where vehicles come from opposite directions?

When driving on a road without a centerline, it is essential for drivers to give at least half the road to oncoming traffic. This principle promotes safety by ensuring that both vehicles can pass each other without risk of collision. By providing ample space, drivers reduce the likelihood of side-swipe accidents, which can occur when vehicles are too close in proximity.

In such scenarios, it's vital to remain aware of the road conditions and the size of the vehicles involved. Maintaining a safe distance allows for proper maneuvering, especially in the event that one vehicle needs to adjust its position to accommodate the other. Adopting this practice not only promotes a smoother flow of traffic but also encourages cautious driving behavior in situations where visibility may be limited or when the road's physical characteristics don’t clearly define driving lanes.
