What is indicated by a vehicle displaying a reflective orange and red triangle?

The reflective orange and red triangle is a universal symbol indicating that the vehicle it is displayed on is a slow-moving vehicle. This sign is notably used for vehicles that cannot maintain a speed above 25 mph, such as farm tractors, construction equipment, and certain types of non-motorized vehicles. The purpose of this symbol is to alert other drivers to be cautious and maintain a safe distance, as slow-moving vehicles can pose a hazard on roadways, especially if they are in areas where faster traffic is common.

By using this distinctive marking, other motorists can quickly identify the need to be vigilant, allowing them to adjust their speed or lane position as necessary to ensure safety for everyone on the road. Understanding this sign's meaning is essential for all drivers, especially in rural or semi-rural areas where encounters with slow-moving vehicles are more frequent.
