What does sign L4 prohibit at certain hours?

The correct answer, which indicates that the sign prohibits stopping at certain hours, is based on the specific regulatory function of this sign. Signs that prohibit stopping are often implemented in busy areas where congestion may occur, such as near schools, hospitals, or high-traffic roads. The restriction on stopping helps ensure the flow of traffic remains uninterrupted and enhances overall safety.

Understanding this prohibition aids drivers in making informed decisions about where they can and cannot stop their vehicles, contributing to smoother traffic movement, reducing potential accidents, and maintaining accessibility for emergency vehicles. In areas where stopping is disallowed, it is typically intended to keep the road clear and prevent obstruction that could lead to further complications in traffic dynamics.

The other options may relate to vehicle movement or restrictions but do not accurately represent the specific message conveyed by sign L4 regarding stopping.
