Final answer:
School zones and business districts usually have lower default speed limits to ensure pedestrian safety. The typical speed limit in these areas ranges from 20-35 miles per hour, though penalties are more severe for speeding, especially during active school hours. Knowing the de facto speed limit and the potential for a traffic ticket is important.
Step-by-step explanation:
If a speed limit is not posted in a school zone or business district, certain default speed limits may apply depending on the jurisdiction. Typically, these limits are lower than other areas to enhance safety for pedestrians and students. It's crucial to be aware that fines for speeding in these areas are often higher, especially during school hours.
In the case of a school zone, if no signs are posted, the de facto speed limit is usually around 20-25 miles per hour. For a business district, the limit could vary but it often falls between 25-35 miles per hour. Regardless of the set speed limits, it's essential to drive at a safe speed considering the road conditions and environment. Furthermore, enforcement may include a buffer over the posted speed limit, but continuously driving over the speed limit, even by a small margin, increases the risk of receiving a traffic ticket.
