Washington Is it legal in Washington to drive with the doors off?

My wife just got a fix it ticket for driving with her doors off. 2 mirrors installed. Cop said she had to have the metal bars or put the doors back on. Said to send a picture with doors on or he will send another ticket.
That ticket is BS. I just took my daughter down to the 911 Driving School in Spokane, WA. She takes her driving test on Tuesday of next week. I took a pic of the page they gave her with information that indicates driving with doors off WHILE TAKING THE STATE DRIVING TEST in WA is totally legal.
