When is it not permitted to drive to the left of the center line of a highway designed for more than one lane of traffic?

Driving to the left of the center line of a highway designed for more than one lane of traffic is not permitted under any of the conditions listed. This is primarily for safety reasons, as each scenario poses a significant risk for collision or loss of control.

When approaching a level railway crossing, visibility can be severely limited, making it dangerous to maneuver into oncoming traffic. Similarly, driving near a bridge or tunnel where the view is obstructed can prevent a driver from seeing if another vehicle is approaching, thus increasing the risk of accidents. Additionally, approaching the crest of a grade (a hill) or a curve can create blind spots, meaning that vehicles could be coming from the opposite direction without any warning.

These conditions are designed to protect drivers and ensure that they remain in their designated lane, minimizing the potential for head-on collisions and other dangerous encounters on the road. The regulation emphasizes maintaining a safe distance from potential hazards and ensures that all traffic flows smoothly without unexpected intrusions into oncoming lanes.
