Final answer:
An orange colored triangle shaped sign on a truck indicates that it is a slow-moving vehicle, specifically traveling at less than 25 mph, to alert other drivers.
Step-by-step explanation:
An orange colored triangle shaped sign on a truck means that it is a slow-moving vehicle. Specifically, option A is correct, indicating that such a sign denotes the vehicle is traveling at less than 25 mph. These signs are typically found on the rear of vehicles that are not designed to travel at high speeds, such as farm equipment, in order to alert other drivers to the potential difference in speed and to encourage caution when approaching and passing them.
The orange colored triangle shaped sign on a truck indicates that it is a slow-moving vehicle. This means that the truck is traveling at a speed of less than 25 mph. The purpose of this sign is to alert other drivers to the slower speed of the truck and allow them to adjust their driving accordingly.
Therefore the correct answer is A) It is a slow-moving (less than 25 mph) vehicle.
