When executing a sharp right turn at a narrow city intersection, how must the driver handle the tractor-trailer to prevent the trailer wheels from hitting the curb?

1. Perform a buttonhook turn: drive the tractor straight into the intersection past the curb line, then steer left slightly before turning right
2. Perform a jug-handle turn: steer the tractor wide to the left lane *before* entering the intersection, then turn right
3. Back up in the middle of the turn to adjust the angle
4. Drive faster to slide the trailer wheels around the corner
