What does a single yellow line on the road signify?

A single yellow line on the road indicates that parking is prohibited during specific hours, often related to business hours or peak traffic times. This regulation aims to ensure that roadways remain clear and accessible for the flow of traffic during those busy periods, promoting safety and efficiency on the roads.

The presence of a single yellow line does not mean that stopping is never allowed; in fact, drivers may be able to stop temporarily to drop off or pick up passengers, provided they do not violate the designated restrictions outlined by accompanying signage. The other options refer to situations that are either too permissive or too restrictive compared to what a single yellow line indicates.
