Are CALTRANS vehicles classified as "emergency vehicles"? Seems to me the code only speaks to fire, ambulance, LE, and tow trucks? Maybe that's not the revised code?
My bad, I see at the end of the code that it expires 1/1/10 unless a new code is enacted.The original code only addressed fire, police etc..
The Current law requires motorists to only yield to law enforcement, emergency responders or tow truck operators who are working on the roadside.
The code has changed to reflect CALTRANS
A new law goes into effect on January 1 that increases safety measures for all Caltrans highway workers.
January 1, 2010. At that time, motorists will have to slow down and, if safe, move over to a lane not immediately adjacent to the stationary vehicle.
The law does not apply when the vehicle with flashing warning lights is not adjacent to the freeway or is separated from the freeway by a protective physical barrier.
