Drivers who fail to use their turn signals at an intersection.
You are waiting for a light to turn green while in the left lane. The light changes but the vehicle in front of you is not moving. Unfortunately for you, that city of Seattle driver wants to take a left turn but failed to signal.
Had he done so, however, you could have easily gone around him. But now you are stuck behind him while everyone else is passing you on the right. Frankly, many of our Seattle traffic ticket attorneys wish City of Seattle police officers took it upon themselves to write a few more tickets under RCW 46.61.305 in these types of instances, as opposed to ticket a guy for making an unsignaled lane change when no one is within 500 yards of him.
