What does "NO STANDING PM Rush Hours" indicate?

The indication "NO STANDING PM Rush Hours" specifically means that vehicles are not allowed to stop, stand, or park in that area during the designated times identified as "PM Rush Hours." This restriction is typically enforced to keep traffic flowing smoothly during busy periods, as it prevents drivers from stopping their vehicles and potentially causing congestion. It clearly highlights that stopping or parking is prohibited, making option A the best interpretation of the sign's meaning.

Other options misinterpret the sign’s intent; for instance, the notion that parking is allowed anytime does not hold true as it directly contradicts the essence of the prohibition outlined in the sign. Similarly, limitations specified only to morning hours or suggesting standing at the curb do not align with the clear message that prohibits stationary vehicles during peak traffic times.
