Kentucky CAR DMV Practice Test 18

It is not advisable to drive after drinking any amount of alcohol. Even a single drink will affect your ability to drive safely.

Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

Expect a train on any track, at any time, traveling in either direction. If you need to stop after crossing the tracks, wait until you can completely cross the tracks before proceeding. Make sure your vehicle clears the tracks before you stop.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited.

Children on bicycles are sometimes unpredictable. Young bicyclists are especially likely to make surprising changes in direction. Remember that children and bicycles are both small in stature and may become difficult to see.

You should avoid passing other vehicles on two-lane roads. Every time you pass a vehicle, your odds of being in a collision increase.

Yellow lane markings indicate a separation of lanes where traffic is traveling in opposite directions. When you see double solid yellow lane markings, passing is prohibited from both directions.

When planning to back up your vehicle, check behind the vehicle before getting in. Children and small objects may be difficult or impossible to see from the driver’s seat.

You may never drive off the paved or main-traveled portion of the road and onto the shoulder to pass another vehicle.

As daylight begins to fade, turn on your low beams to help others see you. Only use your high beam headlights in an open area where no other drivers are present.

Before changing lanes, you should check your side mirrors and look over your shoulder to make sure it is safe to proceed.

If you have started to make a turn, follow through. Swerving back into your previous lane at the last moment can cause collisions.

If multiple vehicles arrive at the same time to an intersection that is not controlled by signs or signals, the driver on the right has the right-of-way. Drivers should then proceed in the order that they arrive to the intersection.

Alcohol reduces all of the important abilities you need to drive safely. Alcohol goes from your stomach to your blood, then from your blood to all other parts of your body. Alcohol affects the areas of your brain that control judgment and skill.

If a traffic signal is displaying a steady red arrow, traffic in the indicated lane may not proceed in the direction shown by the arrow. Drivers must come to a full stop and wait for a green signal to proceed.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers that another road crosses the highway ahead.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.

When entering and driving through a work zone, slow down and be prepared to stop. Obey posted speed limits and be alert to conditions around you. Workers could be present.

Blood alcohol concentration (BAC) is a measure of the percentage of alcohol in a person's blood. The higher the BAC, the more impaired a person is.

If an oncoming driver fails to dim their high beams, you should avoid looking directly at the headlights. Instead, look toward the right edge of your lane and watch the oncoming vehicle out of the corner of your eye.

With decreased visibility and the glare of oncoming headlights, you cannot see as far ahead at night as you can during the day. Always use headlights and exercise caution when driving in the dark.

On rainy, snowy, or foggy days, it may be difficult for other drivers to see your vehicle. Under these conditions, headlights make your vehicle easier to see. If the weather requires you to turn on your windshield wipers, you must also turn on your low beam headlights.

If you miss your turn or exit, do not back up in the travel lane or on the shoulder. Continue to drive to the next exit or crossroad. Drivers do not expect a vehicle to be backing toward them on the roadway and doing so will likely cause a collision.

You may turn left onto a one-way street that moves to the left if there is no sign prohibiting the turn. You may not turn left onto a one-way street where traffic moves to the right.

When backing up, place your right arm on the back of the passenger seat and look directly through the rear window. Do not depend on your rearview or side mirrors as mirrors do not show directly behind your vehicle. Only drive in reverse at a low speed.

Even if your light is green, you must not enter an intersection unless you can get completely through the intersection before the light turns red. If you block the intersection, you can be cited.

If a tire suddenly blows out while you are driving, hold the steering wheel tightly and keep the vehicle going straight.You should slow down gradually, taking your foot off the gas pedal and using the brakes lightly. Do not stop on the road if at all possible. Pull off the road in a safe place.

Never pass within intersections or at other intersecting points, such as parking lot entrances and alleyways. Any time your view is blocked by a curve or a hill, you should stay in your lane and assume that there is an oncoming vehicle just out of sight. Wherever signs and/or pavement markings permit passing other vehicles, you will have to determine whether or not you have enough space to pass in a safe manner.

You should always change lanes gradually and carefully. Only change lanes when necessary. Every lane change increases the possibility of a traffic accident.

At a stop sign, you must come to a full stop and check for traffic in all directions before proceeding.

When traffic permits, you should make room to allow vehicles to merge into your lane.

If you are entering interstate traffic from an acceleration ramp, you should yield to drivers already on the interstate highway. Merge safely into traffic when you are able to do so.

While waiting to turn left, keep your wheels pointed straight ahead until it is safe to start your turn. If a vehicle hits you from behind, this will prevent you from veering into oncoming traffic. When parked facing either uphill or downhill, turn the wheels so the vehicle will not roll into traffic if the brakes fail.

Orange, diamond-shaped signs are used to mark construction, maintenance, survey, and utility work areas. These signs help direct drivers and pedestrians safely through dangerous zones. Fines for traffic convictions may double in areas marked by these signs.

When driving on a state highway, the speed limit is 55 miles per hour. If a different speed limit is posted, follow the posted speed limit.

Legal prescription and over-the-counter drugs can impair your ability to drive, including drugs taken for colds, hay fever, allergies, or to calm nerves or muscles. It is illegal to drive while under the influence of any drug that impairs your ability to drive safely; this law does not differentiate between illegal, prescription, or over-the-counter drugs.

If you are in a lane corresponding to a signal displaying a green arrow, you may proceed in the direction of the arrow when the way is clear. This is true whether the arrow is displayed alone or together with another signal.

This sign indicates that there is a crossroad ahead.

This sign is placed on roads near schools to warn drivers to slow down, drive with caution, and watch for children.
