Final answer:
The prima facie speed limit in a business or residential district is typically 25 mph.
Step-by-step explanation:
"Prima facie" is a Latin term that translates to "at first sight" or "on its face." In the context of speed limits, a "prima facie speed limit" refers to a speed limit that is presumed to be reasonable and proper based on the conditions, even without further evidence. In other words, the speed limit is considered valid on its face, and a violation can be charged without additional proof of the speed being unsafe. The prima facie speed limit when driving in a business or residential district is typically 25 mph (Option 1). This speed limit is set to ensure the safety of pedestrians and vehicles within these areas. It is important to follow the posted speed limits to avoid potential accidents and traffic violations.
