What is considered a violation of parking rules in relation to bus zones?

Parking in a designated bus zone is indeed considered a violation of parking rules because these zones are specifically designated to ensure the safe and efficient operation of public transportation. Bus zones are critical areas where buses need to pull over to pick up and drop off passengers without interference from parked vehicles. Ensuring that these zones are kept clear is essential for maintaining the flow of traffic and reducing delays for public transport. When vehicles are parked in these zones, they obstruct the bus's ability to safely access the curb for passenger pick-up and drop-off, which can create safety hazards and inconveniences for commuters.

In contrast, although options like parking too close to a bus stop and stopping temporarily to drop off passengers involve proximity to the bus stop, they may not constitute direct violations of designated bus zone regulations. Parking less than 10 feet from a bus stop specifies more about clearance than the outright violation of occupying a designated space meant solely for buses. Thus, the clear violation highlighted by parking in a designated bus zone captures the essential rules surrounding public transportation safety and accessibility.
