When turning right, turn as wide as possible while remaining in your lane and keep the rear close to the curb. You can turn late if traffic is clear in the lane next to your destination lane is clear. Do not swing into the left lane before starting a turn as traffic may falsely believe you are turning to the left.
All choices
