What is the speed limit in residential areas in Arkansas unless posted otherwise?

Answer: B — 25 miles per hour

In Arkansas, the default speed limit in residential areas is set at 25 miles per hour unless local signs indicate otherwise. This speed limit is designed to enhance safety in neighborhoods where pedestrians, children, and pets are often present. The 25 mph limit helps to minimize the risk of accidents, allowing drivers adequate time to react to sudden obstacles or changes in the environment. It encourages a safer driving atmosphere and aligns with the generalized traffic regulations aimed at protecting residents in more populated areas.
