Turn signals
Signals tell other drivers where you intend to go; you must signal before turning, changing lanes, exiting a roundabout or pulling away from a curb, after checking traffic ahead, behind and beside. In moving traffic, signal at least 100 feet before the turn or lane change; parked at a curb, signal long enough to alert traffic before re-entering. Hand-and-arm signals may be used only in daylight when people and vehicles are clearly visible at 1,000 feet, never at night, in poor visibility or from a wide or long vehicle: arm straight out for a left turn, bent up for a right turn, bent down for stopping or slowing. Never rely solely on another driver's signal, since the driver may signal right and turn left, or turn without signaling.
Turns
Turning rules apply everywhere, including driveways and alleys. Check behind and beside you well before turning and turn smoothly at lower speed. You may turn across a bicycle lane but never move into one to prepare for a turn; check the blind spot over your shoulder and in the mirrors for riders who may come up beside you, yield to bicyclists in a bike lane or on a sidewalk, and check the crosswalk and stop for pedestrians. Lane-use signs and markings may direct you into the correct lane; if you are in the wrong lane at an intersection, go on to the next one, since driving around the block is safer than a last-minute lane or direction change. For a right turn, get as near the right curb or edge as you can and just before entering look left, front, right and left again. For a left turn on a two-way road, approach in the lane just right of the center line, look left, front, right and left again for oncoming and cross traffic, yield to oncoming traffic as the law requires, turn just before the imaginary center point of the intersection and drive into the lane just right of the center line of the new road; turning left onto a two-way road against a red light is illegal, and where a left-turn lane exists you must use it. From a one-way road to a one-way road, approach in the lane nearest the left curb and turn into the nearest left lane, a turn you may make on red after stopping and yielding to traffic and pedestrians. From a two-way road to a one-way road, approach in the lane nearest the direction of the turn and turn into the nearest lane, also allowed on red after stopping and yielding. From a one-way road to a two-way road, approach in the lane nearest the left curb and turn into the lane just right of the center line, never against a red light. Dual turn lanes let several lanes turn the same way when signs or markings permit; follow the markings and stay in your lane when turning onto a road with more lanes than you left. The general rule is to turn from the nearest lane in your direction to the nearest lane in the new direction, without swinging wide or changing lanes mid-turn, the two classic errors being turning into the wrong lane and turning from the wrong lane. U-turns are prohibited at signalized intersections unless a sign permits them, between intersections in a city, anywhere inside city limits where traffic from either direction cannot see you within 500 feet, anywhere outside city limits where you cannot be seen within 1,000 feet, at or on a railroad crossing, and wherever signs or markings prohibit them.
Intersections
Stop signs, yield signs and signals control busy intersections, but a defensive driver never assumes they will stop approaching traffic. At a stop sign, steady red or flashing red, stop before the marked stop line or crosswalk, or with neither, before the unmarked crossing area at the edge of the intersection; always yield to vulnerable users such as pedestrians and bicyclists and to traffic in the intersection when making an allowed turn; if you cannot see left and right after stopping, pull forward slightly and scan; and even on green, do not enter unless there is room for your vehicle on the other side. At a four-way stop, courtesy lets the driver who stopped first go first, and in doubt you yield to the driver on your right, never assuming another driver will yield. At a two-way stop with signs facing each other, the driver turning left yields to approaching traffic going straight. At an intersection with no signs or signals, look left first to be sure cross traffic is yielding, then front and right, be ready to stop, yield to any vehicle in the intersection or approaching from your right, and check again as you enter. On a road ending at a T-intersection with no controls, yield to drivers on the through road.
Roundabouts
Roundabouts, rotaries and traffic circles are circular intersections with a center island around which traffic moves one way, counterclockwise, marked ahead by a warning sign with arrows in a circle. Approach: slow, read the signs to find your exit, watch for bicyclists who will either merge into traffic or use the sidewalk, and stop for pedestrians in the crosswalk in your lane. Enter: yield to traffic inside and exiting the roundabout, wait for a gap and merge, ready to stop. Proceed: circle to your exit, give bicyclists who merged the full lane and never pass one inside. Exit: signal right and watch for pedestrians in the crosswalk. In a multi-lane roundabout, read the exit and lane-use signs and markings before entering, enter in the lane for your exit, hold your lane and avoid changing lanes inside, and never overtake anyone, especially trucks and trailers, which may straddle both lanes; passing or driving beside a truck inside a roundabout is illegal. When an emergency vehicle approaches, do not enter; pull right and let other vehicles clear the intersection; if you are already inside, never stop but drive through, exit, and then pull to the right shoulder.
Parking
Leaving any parked or stopped position, check your blind spots and mirrors and yield to all traffic. Parallel parking: park in the direction of travel, parallel to and no more than 12 inches from the curb, or as close as possible to the shoulder edge with no curb, with the wheels inside any marked space; pull even with the car ahead of the space, back slowly toward the space turning the wheels sharply, then straighten. Angle parking is common in lots, shopping centers and wide streets; large vehicles should avoid spaces that obstruct the road, and signs may require reverse-angle or back-in parking. On a hill, always set the parking brake, leave a manual in gear or an automatic in park, and turn the front wheels so a brake failure cannot send the car downhill: downhill against a curb, toward the curb; uphill against a curb, toward the travel lane; with no curb, toward the edge of the road. Spaces for persons with disabilities, marked on the ground and by a sign at the front, are only for vehicles with a valid disabled parking permit, and parking there without one even for a few minutes brings fines from $165 up to $1,000. Stopping and parking rules apply whether or not you are in the vehicle, except when it breaks down and cannot be moved or there is no room on the shoulder. You may not stop or park in a traffic lane on any highway, street or road; within an intersection; on the road side of a parked vehicle (double parking); on a sidewalk, crosswalk, bike lane or path; on railroad or light rail tracks; on a bridge, overpass or in a tunnel; between the separate roads of a divided highway; near construction where you would interfere with traffic; where signs, devices, diagonal stripes or markings prohibit it; in front of a driveway; within 10 feet of a fire hydrant; within 15 feet of a fire station driveway on the same side or 75 feet on the opposite side; within 20 feet of a marked or unmarked crosswalk at an intersection; within 50 feet of a signal or sign your vehicle would hide; within 50 feet of the nearest rail of a railroad or light rail crossing; or within 7½ feet of tracks when that interferes with a train. In an emergency you may stop or park temporarily where it is normally forbidden as long as you create no hazard, with the hazard lights on; you may park on a highway shoulder if passing traffic has room, and if your vehicle cannot be seen from 200 feet in each direction you must warn approaching traffic with flags, flares, signs, signals or flaggers placed at least 200 feet away in each direction. Leaving a vehicle unattended, turn off the engine, remove the key, set the brakes and turn on the hazard lights. An officer may have a vehicle removed from a prohibited or hazardous spot at your expense for towing and storage.
