A driver is guilty of making an improper right turn if the approach for the right turn, or the turn itself is not made as close as practicable to the right curb, or edge of the roadway.

An improper left turn on a two-way roadway occurs if the approach for the left turn is not made in the portion of the right half of the roadway nearest to the center line. The turn must be made by passing to the right of the center line where it enters the intersection and after entering the intersection, the left turn must be made so as to leave the intersection to the right of the center line of the roadway being entered.

An improper left turn on a road other than a two-way roadway occurs when the driver does not approach the intersection in the extreme left lane lawfully available for traffic. The turn is also improper if after entering the intersection, the turn is not made so as to leave the intersection as nearly as practicable in the left lane lawfully available to traffic moving in such direction upon the roadway being entered.

The fines for this offense are between $52 and $202. Three points are assessed on a driver if they make an improper right or left hand turn.
