In which situation is idling a vehicle legally permissible in a no standing zone?

In a no standing zone, idling a vehicle is legally permissible when passengers are actively entering or exiting the vehicle. This allows drivers to assist passengers, such as the elderly or those with disabilities, in getting in and out of the vehicle, thus ensuring safety and convenience. The law typically recognizes that such activity contributes to the flow of traffic and the overall efficiency of transportation, as long as the action is brief and necessary for the passengers.

In contrast, accruing idling when no passengers are present or when the driver is away from the vehicle is not justified within a no standing zone, as it defeats the purpose of the regulation aimed at keeping traffic moving. Additionally, idling for any reason other than assisting passengers does not provide a valid exception, and general regulations against idling remain strict.
