Make sure the lane is clear in both directions and then turn only when it is safe. Look for vehicles coming head on toward you in the same lane as they start to make their right
When TURNING RIGHT FROM A SIDE STREET or driveway, signal, wait until it is safe, then drive completely into the center right turn lane.

Come to a complete stop in the center lane if necessary. Enter the traffic stream only when it is safe.
