Final answer:
Passing on the right is not permitted when there is a solid yellow line, a no-passing zone sign, a pedestrian crossing, or a vehicle stopped at a crosswalk. These rules are essential for the safety of all road users and ensure orderly traffic flow.
Step-by-step explanation:
The question asks about specific situations in which passing on the right is permitted and when it is not. Passing on the right is generally allowed on highways with at least two lanes traveling in each direction, when passing a vehicle that is in the left turn lane, and on one-way streets if all the lanes are moving in the same direction. However, it is not permitted:
- When there is a solid yellow line on the left side of the road.
- When there is a no-passing zone sign.
- When there is a pedestrian crossing.
- When there is a vehicle stopped at a crosswalk.
All these restrictions are put in place for safety reasons, whether to ensure the safety of pedestrians or to maintain orderly traffic patterns where visibility or road conditions do not allow for safe passing on the right. It's essential to obey traffic signals and signs to prevent accidents and maintain safety for all road users.
