Lane sweeping is not what you think – a person with a broom sweeping a lane. Lane sweeping is avoiding a lane of traffic in order to get into another on a turn. However, some studies have shown that 50% of drivers commit lane sweeping turns. Lane sweeping is extremely dangerous and can cause severe car accidents and injuries.
If you are turning right or left, you must turn into the lane closest to you. You may not turn into the next lane over just because that is the more ideal lane that you want to be in. You must first enter the lane closest to you and then signal and change into that lane 100 feet later and not immediately.
If someone hits you because they are lane sweeping, they are at fault. You have the right to the closest lane to you and they have the right to the lane closest to them. It can be difficult to maneuver if you are the one turning left and there are cars that could be going straight or turning. You should make sure you recognize the intention of the driver in front of you before proceeding into a left hand turn across oncoming traffic without a green arrow. If a car is going straight, they have the right of way in a non green arrow situation.
