What is the requirement for animal-drawn vehicles or farm tractors operating on a highway at night?

The requirement for animal-drawn vehicles or farm tractors operating on a highway at night is that they must have a white light on the front and two red lights on the rear. This is essential for visibility and safety on roadways, especially in low-light conditions. The white light at the front helps other drivers see the vehicle from a distance, while the two red lights at the rear indicate the presence of the vehicle to those behind it. This lighting configuration is designed to reduce the risk of collisions, ensuring that all road users can effectively gauge the size, direction, and speed of the slow-moving vehicle.

Other options, while related to safety, do not meet the specific legal requirement for night-time operation. Flashing lights on the sides, for example, might provide some additional visibility but are not mandated for such vehicles. A reflective triangle at the back is helpful for indicating the vehicle’s presence, but it does not substitute for the required lights. Lastly, the stipulation regarding speed exceeding 25 mph does not apply as the presence of front and rear lights is critical regardless of how fast the vehicle is moving, particularly since many farm tractors and animal-drawn vehicles operate at much lower speeds.
