The requirement for signage on a truck used for towing stipulates that it must be displayed on both sides of the vehicle. This is essential for safety and visibility, ensuring that other drivers can clearly see the warning or identification of a towing operation from multiple angles. Towing vehicles often operate under different conditions compared to standard vehicles, so having signage on both sides helps to inform other road users about the presence of a trailer or towed load, which can be crucial for maintaining safe distances and avoiding accidents.

Providing signage on just the rear would limit the visibility to vehicles approaching from behind, while signage only on the front windshield or solely on the trailer fails to communicate important information to those beside and approaching the vehicle. Having the signage on both sides ensures comprehensive communication across the roadway, thereby enhancing overall safety during towing operations.
