What is the speed limit in a school zone in New Jersey?

Answer: B — 25 mph

In New Jersey, the speed limit in a school zone is set at 25 mph. This limit is designed to enhance safety for children and pedestrians around schools, where there is typically a higher concentration of foot traffic. When passing through a school zone, it's crucial to adhere to this limit, especially during designated school hours, as children may be crossing the street or waiting for transportation. The other limits listed may apply in different contexts. For example, a 30 mph speed limit is common in residential areas or on some main roads, while 20 mph is often used in more specific areas like residential districts during certain times. The 15 mph limit can apply in specific scenarios, such as when driving through certain situations with extraordinary safety concerns, but this is less common. Understanding the specific speed limits in school zones helps ensure the safety of children and encourages responsible driving habits.
