When is it legal to pass another vehicle?

Answer: B — When there is a dashed line and it is safe to do so

Passing another vehicle is legal when there is a dashed line marking on the road, provided that it is safe to do so. The dashed line indicates that passing is permitted in that area, allowing drivers to cross the lane marking when it is safe and clear to pass another vehicle. In addition to the markings, drivers should consider road conditions, visibility, speed limits, and the behavior of other vehicles before making the maneuver. This ensures that the pass is carried out safely without endangering oneself or other road users. Understanding when it is safe to pass is crucial for maintaining roadway safety and is a fundamental aspect of good driving practice.
