I think it is pretty unsafe to pass any line of cars parked at a light, not just big trucks. If you want to be treated as a vehicle, you should act like one. Yes, I know, we get to ride on shoulders and even side-walks, and cities with Bike-boxes actually encouraged cyclists to ride along the ride and move in front of cars stopped at a light. Just doesn’t feel right to me.–Corrie
Trucks have huge blind spots where the driver cannot see the lanes next to and just behind them. Additionally, when they make a right turn, they typically slow down and swing wide left first, which tempts many cyclists to ride up next to them, right into the path of the rear wheels of the trailer.
