True or False: A person may stop or stand on a sidewalk if the vehicle does not impede pedestrian traffic.

The assertion is false. In general, stopping or standing a vehicle on a sidewalk is typically prohibited, regardless of whether it impedes pedestrian traffic. Sidewalks are designated for the use of pedestrians, and vehicles should not occupy this space as it can create safety hazards and impede the flow of foot traffic. While there may be specific local laws or ordinances that address parking regulations, the overarching principle is that sidewalks need to remain clear for pedestrian use. Consequently, stopping or standing on a sidewalk can be seen as an infringement on pedestrian rights and safety, hence the answer is false.
