Lane Use, Passing, and Turning
Lane Use
Keep right except when passing or preparing for a left turn. On multi-lane roads, use the left lane for passing, not cruising. Stay centered in your lane and do not straddle lane lines. When changing lanes, signal, check mirrors, check your blind spot, and move only when clear. HOV lanes may be restricted to vehicles with a specified number of occupants.
Passing Rules
Pass on the left. Before passing, confirm it is legal, signal, check for oncoming traffic, and make sure you can see the passed vehicle in your mirror before returning to the lane. Do not pass on a hill, curve, or anywhere you cannot see far enough ahead; do not pass at a railroad crossing, intersection, or where a solid line is on your side. Never exceed the speed limit to pass. Passing on the right is permitted only in specific situations, such as when the vehicle ahead is turning left and there is room.
Turning
Signal at least 100 feet before a turn. Turn from the proper lane into the corresponding lane-left turns from the leftmost lane into the leftmost lane, right turns from the right lane into the right lane. Do not turn from the wrong lane or swing wide. When turning, yield to pedestrians and oncoming traffic as required.
Traps: questions about passing on the right (limited circumstances only); questions about where passing is prohibited (hills, curves, crossings); and questions about signaling distance (100 feet). Rule of thumb: if you cannot see far enough ahead to complete a pass safely, do not start one.
