Which of the following is a rule for not overtaking?

The rule indicating that you should not overtake where the road is not visible is crucial for ensuring safety on the roads. This guideline is rooted in the need for clear visibility to assess any potential hazards or oncoming traffic that may be present in the area. Overtaking in places where visibility is limited, such as on curves, steep hills, or areas with obstructed views, significantly increases the risk of collision, as drivers cannot see what lies ahead.

The fundamental principle is that safe overtaking requires a clear line of sight to confirm that the maneuver can be executed without endangering oneself or other road users. By adhering to this rule, drivers can help prevent accidents and ensure a safer driving environment for everyone on the road.
