Tow truck flashing amber lights must be seen for a distance of:

Tow truck flashing amber lights are designed to increase visibility and enhance safety while the vehicle is operating on or near roadways. The requirement that these lights must be visible from a distance of 500 feet helps ensure that other drivers have sufficient warning of the tow truck's presence, allowing them to react appropriately, especially in potentially hazardous situations such as roadside assistance or vehicle recovery.

This distance is particularly important because it allows approaching drivers ample time to slow down, change lanes, or take other necessary actions to avoid an accident. The higher visibility distance promotes safety not only for the tow truck operator but also for the general public on the road, thus reinforcing safe driving practices.
