If a load projects from the rear of a vehicle by 1.5m (5 feet) or more, it must be marked with what?

The requirement to mark a load that projects from the rear of a vehicle by 1.5 meters (5 feet) or more is critical for safety and visibility on the road. A red flag or marker during daylight hours, and a red light at night, ensures that the load is clearly visible to other drivers, which helps prevent accidents and collisions.

Using a red flag or marker in the daytime allows for immediate recognition of the extended load, drawing attention to the potential hazard. At night, the red light serves the same purpose, enhancing visibility in low-light conditions and making sure other road users are alerted to the presence of the protruding cargo.

This regulation is in place to maintain safety standards and is enforced to protect everyone on the road, aligning with safe trucking practices and regulations. The other options, while they may offer some level of visibility, do not meet the specific legal requirements for marking a load that extends beyond the vehicle's dimensions in both day and night conditions.
