To make a right turn you should be in the lane closest to the curb. Signal your intent to turn by using the proper turn signal. You should signal at least three or four seconds, 100 feet, ahead of the turn. Look to your left to check the intersection for pedestrians and traffic coming from the other direction. Then brake smoothly before and during the turn. If there is a traffic light or a stop sign at the intersection, come to a complete stop before you make the turn. Turn into the lane closest to the curb unless pavement markings lead you otherwise, and then change lanes if needed.
To make a left turn you should be in the furthest left lane possible, turning into the leftmost lane on the intersecting road, unless pavement markings lead you otherwise; or, unless multiple left turn lanes are provided. If multiple left turn lanes are provided, you should choose the lane that will best serve your need once you enter the intersecting road. Signal your intent to turn by using the proper turn signal. You should signal at least three to four seconds, 100 feet, ahead of the turn. Look in all directions, checking the intersection for pedestrians and traffic coming from the opposite direction.
Keep your front wheels pointed straight ahead until you are actually going to make the left turn. This prevents you from being pushed into oncoming traffic if another vehicle crashes into you from behind. When the way is clear, make the left turn, yield to any vehicles (including bicycles and pedestrians) approaching from the opposite direction.
When two vehicles are approaching each other and signaling to turn left, both vehicles should turn in front of each other so that the passenger sides of the vehicles are beside each other.
U-turns are not legal everywhere. Before you make a U-turn, check for No U-Turn or No Left Turn signs. In business districts, cities and towns, U-turns are allowed only at intersections.
Never make a U-turn on a highway. When making a U-turn, turn on your left-turn signal, stop, and yield for approaching traffic. When the way is clear, proceed into the outside or right hand lane traveling in the opposite direction.
