If there are two lanes available for a left turn, which of the following is true?

Explanation:
When turning left from a two-lane left-turn approach, you must manage your vehicle’s path and stay in the correct lane. Off-tracking is a real effect for longer vehicles: the rear wheels follow a different arc than the front, which can cause the vehicle to swing wider and risk striking the curb or other cars. So, be mindful of where your rear end will travel and position yourself to give plenty of clearance. You should also time the turn so you begin once you’re in a position that allows you to complete the maneuver in your lane, typically after you’ve reached the center of the intersection. This helps prevent blocking cross traffic and keeps the turn predictable and contained within your lane. If there are two left-turn lanes, choosing the lane furthest to the right helps align your path with the cross street and reduces the chance of crossing into the other turn lane or ending up in the wrong placement on the cross street. Together, these points describe safe practice for a left turn with two available lanes, so all of them are applicable in this situation.
