Parking regulations are designed to provide a safe environment.
If the sign states "No Stopping, Standing or Parking" - vehicles cannot stop for any reason. Drop-off and pick-up is not allowed in these areas. These areas are used to reserve space for buses to safely load and unload passengers, and to keep high traffic areas, such as crosswalks, clear for pedestrians.
If the sign states "No Parking" - vehicles can stop briefly in these areas to drop-off or pick-up, but the operator must remain with the vehicle at all times.
If the sign has a time limit restriction (10 minute limit, etc) – vehicles can park in these areas and be left unattended, but only for the allowable time limit on the sign
