You must not pass or go around a vehicle that has stopped for people at a crosswalk, because it may be hiding a child who is stepping into the road. Obeying the school speed limit and letting children cross first are things you must do, not things you must avoid.
Tight or curving roads, intersections, railroad crossings, and wet or slippery pavement all leave less room for error. A lower speed buys you reaction time and cuts the distance you need to stop.
After a blowout, hold the steering wheel firmly, take your foot off the accelerator, and keep the car going straight while it loses speed on its own. Braking hard can make you lose control, so stop only after you have eased off the road to a safe spot.
For drivers 21 and older, the standard legal limit is a BAC of 0.08%. Drivers under 21 are covered by zero-tolerance laws with a far lower limit, so 0.08% is not the cutoff for 18- to 20-year-olds, and 0.06% is not the standard adult limit.
Tip Watch the decimal point closely: the adult limit is 0.08% BAC, not 0.8%.
One standard drink equals either 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of distilled spirits; each holds about the same amount of alcohol. Choosing beer or wine over liquor does not make you any less impaired.
Cutting across a parking lot, gas station, or other property to avoid a sign or signal is illegal. The only exception is when a police officer directs traffic that way.
Blinking your brake lights or turning on the hazard flashers lets the people behind you know early that traffic is stopping for a crash ahead, which gives them room to slow down. These signals warn of danger or an unexpected slowdown; they are not a way to thank another driver or something to use while reversing out of a parking spot.
Tip Hazard flashers are for warning others of a sudden danger, not for excusing double-parking or for ordinary driving.
Most states require a parallel-parked car to have its wheels within 12 inches of the curb, and some allow up to 18, so staying within 12 inches keeps you legal in either case. A wider gap leaves the car sticking out into the travel lane, where it becomes a hazard to passing traffic.
Tip A gap of roughly 6 to 12 inches keeps you within the limit while protecting your tires from the curb.
Highway traffic moves fast, so situations change in seconds. Paying full attention, scanning constantly, and being ready for hazards such as debris, stalled cars, or sudden braking all help you avoid a crash.
When wipers quit during rain or snow, your view is nearly gone. Slow down, and if looking out the open driver's window is your only means of seeing ahead, do so; brake and leave the road at the first safe chance. Once stopped, put on your hazard flashers and wait until the weather clears or the wipers are repaired.
Set the front wheels so that the curb would stop the car if it started to roll: angle them toward the curb if the car points downhill and away from it if the car points uphill. Apply the parking brake every time.
Tip Downhill means wheels toward the curb; uphill with a curb means wheels away from it.
Before you back up, change lanes or brake suddenly, check the traffic behind you with your mirrors and by turning your head. Look over your shoulder through the rear window when backing, and check your blind spot before moving into another lane. These are the moments when a collision with someone behind you is most likely: backing takes you toward whatever is back there, and if you change lanes or brake hard, a vehicle coming up behind you may have no room to avoid you.
Kentucky makes an alcohol driving education program part of the sentence for anyone convicted of DUI, together with fines, a suspended license and possibly jail. The fines and jail terms the law sets are much higher than $100 or 12 hours, and a conviction is never settled with a mere warning.
Total stopping distance is the ground you cover while reacting plus the distance needed to brake, which depends on speed, brakes, tires, and the road surface. Darkness can make hazards harder to spot, but the clock itself does not change how far the vehicle needs to stop.
Tip When judging how quickly you can stop, think about speed, reaction time, brakes, tires, and pavement, not the hour.
No one number is safe in every situation. Choose your speed based on the weather, the road surface, how far you can see and how heavy traffic is, and remember that driving under the limit can still be too fast in poor conditions.
The law requires headlights starting 30 minutes after the sun sets and ending 30 minutes before it rises, which means that in the morning you can turn them off when sunrise is half an hour away. Leave them on longer when rain, fog, or snow limits visibility.
When a crash cannot be avoided, the goal is to reduce the force of the impact. Something that yields absorbs energy better than a rigid object, a stationary object is less violent to hit than an oncoming vehicle, and a glancing contact is far less dangerous than a direct, head-on hit.
School zones commonly carry a 25 mph limit while children are present, for example when a crossing guard is leading students across the street. Where a different limit is posted, the posted sign takes priority, and you should always watch for children stepping into the road.
Water on the pavement makes stopping take longer, so open up a gap of at least 4 to 5 seconds behind the vehicle ahead. Brake, steer and accelerate gently to avoid skidding.
Tip On wet pavement, plan on about twice your usual following distance so you have room to stop.
Kentucky's driver manual sets a minimum following distance of 4 seconds: once the red car passes a fixed point, the blue car's driver should be able to count four seconds before reaching it. Bad weather calls for even more room, and a gap of 1 second or less is far too short.
Passing must always be done on the paved, main part of the road. Pulling onto the shoulder or dirt edge to get by is never allowed, even next to a vehicle that is turning left.
Headlights are required from half an hour after sunset until half an hour before sunrise, plus whenever rain, fog, snow, or dim light makes people and vehicles hard to see. They help you see the road and help others see you.
Slippery pavement gives your tires less traction, so lose speed before a curve or intersection rather than while you are in it. Speeding into a curve, or waiting until you are already descending a hill to downshift, makes a skid more likely.
When drivers arrive together, each yields to the vehicle on the right, and a driver turning left must also wait for oncoming traffic. Nobody is to the yellow car's right, so it leads; the blue car has the yellow car on its right and goes next; the truck is turning left in front of the oncoming yellow car and has the blue car on its right, so it goes last.
Tip Where no signs or signals control an intersection, a driver turning left must wait for oncoming vehicles that are going straight or turning right.
To indicate a right turn, stick your left arm through the driver's window and bend it up at the elbow so your hand points toward the sky. A straight, extended arm signals a left turn, while an arm bent downward signals that you are slowing down or stopping.
A siren or flashing red or blue lights mean an emergency vehicle needs the road. Move to the right edge, stop, and stay there until it has gone by; failing to do so breaks the law and puts lives at risk.
If a school bus stops on a two-lane road with its red lights flashing, traffic approaching from either direction has to stop and stay put until the lights go off and the bus moves on. Simply slowing down is not sufficient, including when the bus is on the opposite side of the road.
Tip Drivers on the far side of a highway split by a physical divider, such as a raised median, are not required to stop.
With an intermediate license in Kentucky, unsupervised driving is off-limits from midnight until 6 a.m. Trips for work, school or an emergency are allowed if the driver carries the required documentation.
Under implied consent, getting a license and driving on public roads count as advance agreement to chemical testing, such as a breath test, when you are arrested on suspicion of drunk driving. Refusing the test usually brings its own penalties, including loss of your license.
Signaling tells other drivers what you plan to do, and the mirrors show vehicles to the rear and sides. The red zones are blind spots the mirrors miss, so a quick head check over your shoulder is needed to confirm the lane is open before you steer into it.
Alcohol makes it hard to hold a lane, judge speed, and react smoothly, so impaired drivers often weave, drive unusually slowly, and brake or stop without warning. If you notice these signs, keep well back and report the driver to police when it is safe.
A stop sign, a red signal, and a stop order from an officer directing traffic each require a full stop. The same duty applies in other cases too, such as a school bus with flashing red lights or a train approaching a railroad crossing.
Flashing red lights mean the bus is picking up or dropping off children, so traffic behind it must halt and remain stopped until the lights shut off and the stop arm retracts. Slowing down or passing instead is illegal and dangerous. How far back you must stop depends on the state; where the law gives a distance, it is usually 10 to 20 feet.
The headlight requirement begins 30 minutes after sunset, when fading daylight makes it harder for others to see you. Also turn them on at any hour when rain, snow, or fog limits visibility.
The examiner inspects the test vehicle before any driving starts. Any one of these problems, whether an unsafe car, missing seat belts or equipment that keeps the examiner from reaching the brake pedal, is enough to stop the test before it begins.
