Hello, the alliance that i am in is mainly from the UK and here we have vehicles such as highway maintenance and traffic officers which are used on a daily basis.
They have a fleet of traffic officer discoveries and highway maintenance operate clean up crews from RTCs, tow truck services and road maintenance. Maybe, you could add like a utilities team, and the company and vehicles could be named whatever they wanted. The traffic officers could be deployed during road accidents to control the traffic flow, then the clean up crews could come after to clear the scene.
