Step-by-step explanation:
The correct answer to what a sign on the rear of a vehicle means is is traveling less than 25 mph. Road signs provide essential information about the vehicles on the road and what drivers should expect or do in response. For example, signs that indicate a vehicle is moving slower than the regular traffic flow, specifically under 25 mph, serve to alert drivers that they should be prepared to adjust their speed accordingly.
Common signs that you might see include those signaling slow-moving vehicles, such as construction equipment or agricultural machinery. Understanding and obeying these signs are crucial for road safety and ensuring the smooth flow of traffic. If you encounter a vehicle with such a sign, it's important to slow down and keep a safe distance, but passing may still be legally permissible if done safely and where the road laws allow.
Drivers should adjust speed and maintain road safety but can pass if it is safe and legal to do so.
