Hardly believable

No one said anything about the little truck pulling out! In PA if you move over to let someone on to the road it "can" be a violation. That is a courtesy and not required. I was taking my CDL test and a car was yielding up onto the 4 lane. The examiner watched me and must have thought I was going to move over and she said if you change lanes you fail. Just what I know has happened to me.

Also from PA, this is valid. I changed lanes to let someone on to a ramp during my license test and I was failed because I technically 'impeded the fast lane'. This was a good 5 years ago, but if I know PA, it hasn't changed.
