Under what condition can you park on the right-hand side of the road?

Answer: B — Only on a one-way street

Parking on the right-hand side of the road is permitted only on a one-way street because, in these situations, there is no opposing traffic, allowing vehicles to park legally and safely on either side. On a one-way street, the flow of traffic is continuous in one direction, which eliminates the potential hazards associated with parking on the left-hand side when there are vehicles traveling in the opposite direction. Generally, in most places, parking on the right-hand side of a two-way road is prohibited due to safety concerns; it can lead to confusion and danger for oncoming traffic. Therefore, understanding the specific conditions under which parking is allowed is crucial for ensuring road safety and compliance with traffic regulations.
