When is it legal to drive on a sidewalk?

Driving on a sidewalk is generally prohibited, as sidewalks are designated for pedestrian use. However, there is an exception for situations where a driver is entering or exiting a driveway. In this context, it is permissible to briefly drive on the sidewalk to ensure a safe transition from the road to the property or vice versa. This action is typically done at low speeds and with caution, allowing the driver to avoid obstructing pedestrian traffic and to ensure the safety of pedestrians who may be using the sidewalk.

The other options do not align with legal driving regulations. Parking on a sidewalk is not allowed because it obstructs pedestrian traffic and can create hazardous conditions. Driving on a sidewalk when no vehicles are present is still illegal unless it is for the purpose of entering or exiting a driveway safely. Making a delivery does not inherently provide justification for driving on a sidewalk unless the delivery involves utilizing a driveway, which again falls under the permissible use when entering or exiting a property.
