Hand position and speed

Sit straight but relaxed with your hands at 8 and 4 o'clock, holding the wheel with fingers and thumbs rather than palms. A speed limit is the maximum under ideal conditions; you may go slower as long as you do not impede traffic, and you must go slower in posted school and work zones and whenever construction or weather makes the limit unsafe. Driving 20 mph or more over the limit, or over 85 mph anywhere, can be charged as reckless driving, a misdemeanor with fines, suspension or jail, and a possible felony if it kills someone while your license is suspended or revoked. Driving 81 to 85 mph in a 65 zone adds a $100 fine. Radar detectors are illegal in Virginia. Unless posted otherwise the limit is 25 mph in school, business and residential areas, 35 mph on unpaved roads and 55 mph everywhere else; some school zones use photo enforcement.

When you must stop

Always stop at stop signs, red lights and flashing red signals; when entering a street or crossing a sidewalk from a driveway, alley, building or parking lot; at railroad crossings with flashing signals; when a flagger signals; for pedestrians trying to cross at a crosswalk; at an officer's direction (if you flee and the pursuing officer dies as a result, you are guilty of a Class 4 felony); and at the scene of any crash you are in. At a stop sign, stop at the sign even if the car ahead just went, then go when clear.

School buses: stop for a stopped bus with flashing red lights and an extended stop sign when approaching from any direction on a highway, private road or school driveway, and stay stopped until everyone is clear and the bus moves; stop even if the bus is loading or unloading with its signals off. You need not stop when traveling the opposite way on a road divided by a median or barrier with the bus on the other side, but expect surprises from exiting children.

Stopping distance

Stopping distance is perception time (recognizing the hazard), reaction distance (traveled before you brake) and braking distance (traveled after you brake). Weather, visibility and your mental and physical condition affect all three; speed, brakes, tires and pavement affect braking distance, and wet pavement can double it. Learn your antilock brakes from the owner's manual and practice: never pump antilock brakes.

Yielding the right-of-way

Yield also means stop if you cannot merge safely. The vehicle that arrives first goes first; arriving together at an intersection without signs or signals, the driver on the left yields to the right; at a dark signal, everyone stops and the left yields to the right; entering an interstate from a ramp, yield to traffic already on it; entering any intersection or roundabout, yield to traffic in it; from a private road or driveway, stop and yield to all traffic and pedestrians; yield to pedestrians and bicyclists in a marked crosswalk or at an unmarked intersection (turns on red are especially dangerous to them); yield to funeral processions and never cut through, join or interfere (the lead vehicle obeys signs and signals unless police escorted; others follow without stopping and may use hazard lights); and yield to military convoys, never cutting through or joining.

Vehicles with flashing lights. For a stationary emergency vehicle or tow truck with flashing lights, change to a lane not next to it when reasonable, otherwise slow and proceed with caution; violations can bring a court suspension and demerit points. Passing stopped vehicles with hazard flashers, caution signs or lit flares also requires a lane change with caution. For trash collection vehicles on a road of at least four lanes, change to a non-adjacent lane if safe; on fewer lanes or if you cannot move over, slow to 10 mph below the limit and pass at least two feet to the left. For a stationary mail vehicle, proceed with caution at a safe speed. Do not park within 500 feet of fire trucks or equipment answering an alarm. Never follow an emergency vehicle with flashing lights closer than 500 feet. When police, fire, rescue or ambulance vehicles approach from behind with siren or lights, pull to the right edge and stop until they pass; when they approach in the opposite lane on an undivided highway, pull to the edge and stop. These requirements do not apply in work zones.

Roundabouts

Roundabouts have one or more lanes around a center island; entering traffic yields to pedestrians and to traffic already circling, each approach has a yield sign and often a yield line, and traffic moves counter-clockwise. Slow down and read the signs on approach; signal; to turn right stay right on entry, to go straight use either lane of a two-lane roundabout, to turn left stay left; yield to pedestrians, bicyclists and circulating vehicles, obeying any stop or yield sign or signal at the entry; stay in your lane until your exit, signal right, and check over your shoulder for vehicles beside or behind you before changing lanes or exiting.

Changing lanes and passing

Check the side and rearview mirrors, signal, watch for others moving into the same lane, and just before moving glance over your shoulder at the blind spot. Always signal and check traffic when changing lanes, passing, entering or exiting a highway. On a multi-lane highway, stay right if slower than traffic: the left lane is for passing, not cruising. To pass, check ahead, behind and the blind spot, signal, accelerate, and return to the right lane once you see the passed vehicle's front in your mirror; exceeding the limit while passing is illegal; finish before a No Passing zone begins, since being in the left lane there breaks the law. You may pass on the right when the vehicle ahead has signaled and is turning left, with caution, but never by leaving the pavement. Passing a bicycle, moped, power-assisted bicycle or similar device, slow down and pass at least three feet to the left. When being passed, keep a steady speed or slow down. Passing is unlawful on hills, curves, at intersections and railroad crossings (except on roads with two or more lanes your way), off the pavement or on the shoulder, when a school bus is stopped for passengers on a public road (unless a barrier or unpaved median separates the directions) or on a private road, when a solid line marks the left side of your lane, and when approaching a crosswalk where the vehicle ahead or beside you has stopped.

Over-correcting, turning and U-turns

Over-correcting, turning the wheel more sharply than intended so the rear slides toward the outside of the turn, causes many single-vehicle crashes. Slow on curves, and if you leave the road, do not panic: ease off the speed, look where you want to go and steer gently back. For a right turn, use the lane farthest right, signal three or four seconds, 100 feet, ahead, check left and right for pedestrians and traffic, brake smoothly before and during the turn, stop completely at a red light or stop sign, and turn into the lane nearest the curb unless markings direct otherwise. For a left turn, use the farthest left lane and turn into the leftmost lane unless markings or multiple turn lanes direct otherwise, signal 100 feet ahead, look all ways, keep the front wheels straight until you actually turn so a rear-end hit cannot push you into oncoming traffic, and yield to oncoming vehicles, bicycles and pedestrians. Two vehicles turning left toward each other pass in front of each other, passenger sides adjacent. U-turns are not legal everywhere: check for No U-Turn or No Left Turn signs; in business districts, cities and towns they are allowed only at intersections; never make one on a highway; signal left, stop, yield to approaching traffic, and proceed into the outside right-hand lane going the other way.

Signals, space cushion, searching, blind spots

Turn signals are required by law for lane changes, turns and highway entries and exits; use them even with no traffic around. Hand signals: left arm straight out for a left turn, upward for a right turn, downward for slow or stop. Signal three or four seconds (100 feet) ahead, expect drivers to pull out in front of you, and make sure the signal cancels.

Keep a space cushion by staying mid-lane with room ahead and behind. Use the two-, three- and four-second rule: 2 seconds under 35 mph, 3 seconds at 35 to 45 mph, 4 seconds at 46 to 70 mph (the rule does not work above 70). Count from the moment the vehicle ahead passes a fixed object; reaching it early means you are too close. Hand response takes about a half second and foot response about three-quarters of a second, before any delay from fatigue, medication or distraction. Add seconds in bad weather, heavy traffic, poor pavement or a poor vehicle, behind a large vehicle that blocks your view, when exiting an expressway, behind a motorcycle or bicycle, and when tailgated; if tailgated, do not brake suddenly: move over or tap the brakes to flash the lights and slow. Help the driver behind by keeping a steady speed and tapping the brakes before slowing.

Searching means reading the whole scene with moving eyes, focusing 20 to 30 seconds ahead (about a block in the city), scanning side to side, and looking for exhaust, brake or back-up lights and turned wheels that warn a car may pull out. In rural areas watch for hidden intersections, curves, hills, trucks, farm vehicles and bicycles. Before entering an intersection look left, right, then left again, since cars from the left are closer. Check the rearview mirror about every 10 seconds and before lane changes, backing, quick stops and long downhill runs. Set the inside mirror to frame the rear window and the side mirrors so you barely see your own sides; the only sure way to check a blind spot is a quick glance over your shoulder, and never linger in another driver's blind spot: speed up or drop back.
