Authorized

Sign of the times.

Authorized and Emergency vehicles ONLY

Who or what is to determine the parameters of something that constitutes an emergency? Say you see an accident on the other side of the highway and that responding to it is an emergency, does your vehicle count? Or do you decline in the first place, because by time you get to the next exit and turn around to help, the catastrophe will be over and the occupants dead, because you “obeyed” the “sign”.

How about just Emergency and State Employee Use Only.

Everybody understands it is not just for arbitrary u turns.
