What type of lights are required on a vehicle with an arrow board?

The correct answer emphasizes the need for high-intensity rotating or flashing lights on a vehicle equipped with an arrow board. These lights are crucial for enhancing visibility in various weather and lighting conditions, ensuring that the vehicle is easily seen by other road users, particularly in construction or maintenance zones where safety is paramount.

High-intensity rotating or flashing lights serve several important functions. They alert motorists to the presence of a vehicle that may be stationary or moving slowly, and they help convey critical information about roadway conditions, detours, or other hazards. This type of lighting ensures that the vehicle stands out, even in bright sunlight or adverse weather, making it an essential part of traffic control measures in maintenance of traffic operations.

Standard headlights, while necessary for nighttime driving, do not provide the same level of visibility and warning that high-intensity lights do in a work zone context. LED lights could be effective but are not the only type allowed; thus, specifying them alone would be limiting. Dimmed lights would further reduce visibility, which is contrary to the goal of ensuring safety and awareness in high-risk areas.

Overall, high-intensity rotating or flashing lights are a critical part of the safety protocol for vehicles that are utilizing arrow boards, ensuring that they fulfill their role in maintaining
