What action is required when a highways vehicle fitted with a direction arrow is travelling from site to site?

When a highways vehicle fitted with a direction arrow is travelling from site to site, the appropriate action is to cover or remove the direction arrow. This practice is essential for ensuring that the vehicle does not give misleading signals to other road users when it is not actively engaged in directing traffic or managing traffic flow at the work site. Leaving the direction arrow active could confuse other drivers, as it may suggest that the vehicle is providing directionality when it is simply in transit between locations.

Covering or removing the arrow eliminates any potential confusion and aligns with safety regulations and best practices in traffic management. This precaution is crucial for maintaining clear communication and safety on the roads, ensuring that both highway workers and the general public understand the vehicle's function at any given time.
