How do you mark a vehicle at night that has load extends to the rear 4 feet or more beyond body of loaded vehicle?

To mark a vehicle at night that has a load that extends to the rear 4 feet or more beyond the body of the loaded vehicle, you should:

1. Display a red flag or cloth: Attach a red flag or cloth, at least 12 inches square, to the end of the load or vehicle. This flag should be visible from all sides of the vehicle.

2. Use reflective material: Ensure the red flag or cloth is made of reflective material so that it can be easily seen by other road users at night.

3. Attach lights: Place red lights on the rear of the load or vehicle, visible from all sides. These lights should be visible from at least 500 feet away.

4. Use reflectors: Attach red reflectors on the sides of the load or vehicle, extending the entire length of the load. These reflectors should be visible from all angles and should be spaced at regular intervals.

5. Turn on hazard lights: Turn on the vehicle's hazard lights to make the vehicle more visible.

6. Display a sign: Attach a sign to the rear of the vehicle, indicating the load extends a specific number of feet beyond the vehicle's body. This sign should be clearly visible and readable.
