The law says that you have to yield the right of way when exiting a private drive onto the main roadway. I had that happen to me as I was exiting a drive to turn left onto the roadway when two cars to my left stopped to let me out. As I inched forward a car in the left-turn lane from the same direction struck the front of my vehicle. My fault and I got a citation. Oh, and I was driving a marked police cruiser. Yep, you read that right. People trying to be nice to the cop in the traffic jam got me jammed. Oh, and I got a write up to boot. I knew better from all the cites I'd written for the exact same thing over the years.
