When is it permitted to pass on the right side of the road?

The correct choice, which states that it is permitted to pass on the right side of the road when there are two or more lanes in the same direction, highlights an essential rule of safe driving. This rule allows drivers the opportunity to overtake slower vehicles safely, provided that the road conditions meet this requirement.

In scenarios where multiple lanes exist, drivers can use the right lane to pass without infringing on the rights of others or creating hazardous situations that might arise if passing were attempted in a single lane. This passing on the right is acceptable as long as it is executed safely and legal, ensuring that the driver checks for pedestrians, cyclists, and other vehicles that may enter the lane unexpectedly.

Understanding this rule is crucial for maintaining traffic flow and safety on the roads, as it helps prevent congestion and potential accidents that could occur if all drivers were to remain in the left lane to pass slower vehicles.
