Keep right

Drive on the right; the left side is legal only in special cases such as one-way streets and passing. When going slower than the limit on a multi-lane highway, stay in the far right lane unless passing, turning left or avoiding an obstruction.

Speed and stopping distance

Speed sets your stopping distance, along with reaction time: at 55 mph even in ideal conditions a vehicle needs about 211 feet to stop. Each extra mile per hour reduces control and raises the odds that a crash kills. Driving well below the limit is also dangerous: a vehicle far under the posted speed is much more likely to cause or be in a crash than one at normal speed, especially just past a hilltop or curve. Observe posted minimum limits, and if traffic collects behind you, pull over and let it pass. The key rules: never exceed the posted limit or a speed unreasonable for conditions; keep the two-second gap; and the faster you go, the farther ahead you must see.

Unless posted otherwise, the limit is 35 mph in cities and towns, 45 mph for school buses, 55 mph for school activity buses, 55 mph outside cities and towns, and 70 mph on interstates. Conditions change through open country, neighborhoods and school zones; adjust.

Curves and turns

Slow before the curve so you need not brake in it; accelerate gradually through it for traction; if you must brake, do so gradually; begin turning just before the road bends; and keep as far right as you can. Downhill, consider gravity, shift to a lower gear before descending, and brake earlier. For a right turn, hug the right edge so no vehicle can slip between you and the curb, slow before the turn and accelerate slightly after; motorcycles and bicycles are especially hard to see while turning, so signal and look.

Following and changing lanes

Following too closely is a leading cause of crashes. Keep the two-second rule: at least two seconds between the vehicle ahead passing a fixed point and you reaching it. On the open road leave room for a passing vehicle to pull in. To change lanes, check the target lane and the lane beyond it, check mirrors, check the blind spot over your shoulder, signal in advance, then move.

Passing

Look ahead and behind, signal so drivers ahead and behind can plan, and blow the horn to alert the driver ahead, which legally obliges that driver to help you pass. Keep plenty of room and a steady speed, and never pass unless you can see far enough ahead to return before meeting oncoming traffic. The law requires passing at least two feet to the left of the passed vehicle, and the pass is unsafe if that driver must slow to let you back in.

Passing is always unsafe and usually illegal at intersections in cities and towns or at railroad crossings; at marked intersections in rural areas; on any curve or hill where you cannot see at least 500 feet ahead; wherever a solid yellow line is in your lane or the lines are double solid; at intersections or crosswalks where a vehicle has stopped for pedestrians; and wherever you cannot see that the road is clear.

Passing on the right is illegal except on highways with at least two lanes each way, on one-way streets, when passing a vehicle in a left-turn lane, and in a lane set aside for right turns; it puts you on the other driver's blind side. On a three-lane highway, pass only in the center lane where it is marked for passing in your direction, except when the center-lane vehicle is turning left. When you are being passed, you must help: if the passer sounds the horn, move to the right edge and never speed up; speeding up or failing to give way is a misdemeanor if a crash with injury or damage follows.

Backing and parking

Before getting in, check behind the vehicle for children and small objects. Steer with the left hand and look over your right shoulder through the back window, not just the mirrors, and back no faster than 10 mph.

Park on the right except on one-way streets. Before leaving a parallel space, check traffic and signal left (unless parked on the left of a one-way street); if a car ahead is pulling out, slow and be ready to stop. Do not park at an intersection or in front of a driveway; within 25 feet of the curb line of an intersecting street (15 feet of the right-of-way line without a curb); on a crosswalk, sidewalk or bridge; within 15 feet of a fire hydrant or a fire station entrance; on the traveled part of any highway, or on the shoulder unless the vehicle is visible 200 feet in both directions; beside another vehicle (double parking); at no-parking signs; within one block of a fire or fire truck in a city or 400 feet outside one; anywhere in an interstate right-of-way except designated areas or emergencies; or in a disabled space without the plate or placard.

Interchanges and intersections

An interchange crosses roads at different levels; slow and follow the signs for the turn. An intersection is anywhere roads meet or cross, and intersections are the most dangerous places on the road: more than one-third of fatal crashes happen there. On a four-lane highway with a median wider than 30 feet, each crossing is a separate intersection. The law requires you to slow down at every intersection even with the right-of-way. Where there are no signs or signals: the vehicle already in the intersection goes first; vehicles arriving together yield to the right; a driver with the right-of-way may go straight or, after signaling, turn; and even then avoid hitting anyone. When two facing vehicles arrive together and one wants to turn left, the turning driver signals and waits; the driver going straight has the right-of-way. Never change lanes while going straight through an intersection. At a stop sign, stop completely and yield to the through street; at signals, wait for the signal; leaving a private driveway, stop and yield to everyone; at an unmarked intersection with poor visibility, stop, then creep forward. A single-point interchange squeezes two intersections into one signal set over or under a freeway to move heavy traffic quickly.

Roundabouts

Modern roundabouts are smaller than old traffic circles, keep speeds to 15 to 20 mph, and have cut total, head-on, and fatal and injury crashes where they replaced signals and stop signs. A yellow roundabout-ahead sign tells you to slow; yield to vehicles and bicyclists already circulating, who do not yield to you; everyone moves counterclockwise; signal when exiting and yield to pedestrians in the crosswalks. In a single-lane roundabout go a quarter of the way to turn right, halfway to go straight, three-quarters to turn left, and all the way for a U-turn. In a multi-lane roundabout choose your lane from the signs and markings before entering, usually right lane to exit right and left lane for straight, left or U-turn, and never change lanes inside. Give trucks room to straddle lanes or use the truck apron; never enter while an emergency vehicle is passing through, and if already inside, exit first, then pull over; do not pass bicyclists inside; pedestrians use the outer crosswalks.

Railroad crossings

Stop within 50 feet but not less than 15 feet from the nearest rail when a signal warns of a train, a gate is down or a flagger signals, a train within about 1,500 feet sounds its horn and is an immediate hazard, or a train is plainly visible and dangerously close. Never drive through, around or under a closed or moving gate; stopped drivers keep right and do not form two lanes unless the road has four or more lanes. North Carolina has over 5,000 miles of track and 6,800 crossings, and a train at 55 mph needs more than a mile to stop. The train always has the right-of-way, even over police, fire and ambulances. At a crossing with a stop sign, stop fully. As you approach: slow, look both ways, listen, stay alert and watch the signal; never stop on the tracks; approach with caution, prepare to stop, and go carefully after a train passes. Tracks are private property; cross only at designated crossings; yield even at a crossing with only a crossbuck; treat flashing red lights like any flashing red signal; wait for the lights to stop because a second train may follow; and expect school buses, passenger and for-hire vehicles and placarded hazmat trucks to stop at every crossing. If the lights or gates activate while you are already on the crossing, keep moving: the gates are flexible and cannot trap you, but stopped traffic ahead can. Every crossing has a blue Emergency Notification System sign in each direction with the crossing number, railroad name and an emergency phone number. If you stall on or near the tracks, get out immediately, walk quickly along the road away from the tracks, then call the number on the blue sign; a train hitting a 4,000-pound car is like a car running over a soda can.

Bicycle lanes, city, rural and interstate driving

Where a bike lane runs beside the road, watch for a bicyclist going straight as you turn right across it. In cities, watch side streets and quick stops, check the mirror often, and if you are in the wrong lane for a turn, go to the next intersection; keep a margin of safety, communicate, look well ahead, avoid riding beside others (if you cannot see the car ahead's inside mirror you are in its blind spot), never weave, signal early, expect pedestrians and cars from between parked vehicles, and on a one-way street use the center lanes for through travel and the outer lanes for turns. Rural roads are often more dangerous than city traffic: narrower, darker and faster, with slow drivers and wildlife; secondary roads have steeper hills, sharper curves and short sight distances and cannot be driven at highway speed. Interstates are safer, with divided lanes, no crossings, curves, stop signs or signals: plan the trip, check water, oil, tires and fuel, decide your exits, use the acceleration lane to match speed, keep right and pass left, keep the two-second gap (rear-end crashes are the most common), stop at rest areas at least every 100 miles, never stop in a travel lane, and if you break down move far off the road, tie a white cloth to the aerial or left door handle, raise the hood and use flashers at night. Leaving, signal early and enter the deceleration lane without slowing first, then follow the exit speed. Do not drive far below the limit; follow the flow. If you enter an interstate the wrong way, pull to the right shoulder, stop, and turn around when clear, and watch for Do Not Enter signs. If you miss an exit, never slow, back up or turn around; take the next one.
