An option for tow truck and roadside assistance providers to have an option to turn on while they are on the side of the road working doing a accident or helping a stranded motorist on the side of the road.
This would be a button or icon the tow truck driver / roadside assistance drivers can use which will alert the oncoming traffic/ drivers to slow down and move over.

To many lives are lost because nobody slows down and moves over.

There has to be something you can add in the system for this as you have everything else but no protection for the men and women who risk their lives helping stranded motorist on the side of the roads.
