Edmonton has something similar. It seemed like a common sense thing to me, so I assumed a lot of places do this... I have never heard of any problems.nuovorecord said:Oregon has a state law which mandates that traffic yield to buses pulling back into the traffic lane. Most buses are equipped with flashing "yield" lights on the left rear of the bus. To my knowledge, there hasn't been any major controversy over this law, which was passed in 2001.
