At what speed should you typically drive in a residential neighborhood?

Answer: A — 20 mph

A residential neighborhood is an area where people live, with homes, parks, and schools. Residential areas usually have lower speed limits to ensure the safety of children, pedestrians, and cyclists. Driving at 20 mph is recommended to reduce the risk of accidents and to give drivers enough time to react to potential hazards. The other options, 30, 40, and 50 mph, are higher speeds that are more suitable for larger roads like highways or freeways, not for residential areas. Therefore, they are incorrect options.
