Kentucky CAR DMV Practice Test 13

A five-sided sign is used to alert drivers to a school zone. Some pentagonal signs specifically indicate crosswalks within school zones where children or other pedestrians may be present.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

When passing a motorcycle, allow a full lane to the motorcycle. Never crowd into the same lane as the motorcycle. Returning to the original lane too soon can force a rider to swerve to the right and into traffic or off the road.

This sign indicates that there is an intersection with a side road ahead.

Passing areas are based on how far ahead drivers can see. Allow the passing vehicle to re-enter the drive lane as easily as possible to help everyone avoid potential upcoming hazards.

If your vehicle leaves the roadway, hold the steering wheel firmly, release the gas pedal, and gently apply the brakes. Wait until your speed has reduced, check the traffic, and look for a place to safely return to the roadway by merging back into traffic. Overcompensating by jerking the wheel to return to the roadway can cause you to lose control of your vehicle or may cause your car to go into other lanes of traffic.

A traffic signal displaying a flashing yellow light indicates that you should be alert and proceed with caution. Slow down when approaching a flashing yellow traffic signal.

A broken yellow centerline means that a driver may cross the centerline to pass another vehicle on the left as long as there is no oncoming traffic. Drivers should never cross a solid yellow centerline in order to pass.

When a school bus is stopped on the road ahead with its lights flashing and its stop arm extended, you must come to a complete stop and wait to proceed until the lights have stopped flashing and the stop arm is withdrawn. Even after the bus begins to move again, do not proceed until you are sure there are no children crossing the road ahead of you.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

Only use your horn when it is necessary to avoid collisions. Do not use your horn if a driver or bicyclist is moving slowly and you want him or her to drive faster or get out of your way.

Rumble strips create noise and vibrations to warn drowsy or inattentive drivers that they are straying off of the road or are approaching a stop sign or signal.

You must turn on your headlights any time conditions prevent you from seeing other vehicles. Other drivers may have trouble seeing you, too.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers of an upcoming steep hill. Drivers should adjust their speed accordingly to avoid collisions and brake damage.

When passing another vehicle, move back into your original lane only when you can see the passed vehicle’s headlights in your rearview mirror. This ensures that you will have enough room to safely pull back in front of the other vehicle.

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.

At a railroad crossing marked with this sign, a driver should look both ways, listen for any trains, and be prepared to stop if any trains are nearby. Never try to outdrive an oncoming train.

If you start to feel tired while driving, drive to the first available rest stop or service area to take a break, nap, stretch, or change drivers. You should not rely on caffeine pills or energy drinks, as these are not a replacement for rest and may make your driving even more dangerous.

To prevent yourself from becoming an aggressive driver, concentrate on driving and don't take the actions of other drivers personally. Be realistic about your travel time, drive within posted speed limits, and be forgiving of other drivers using the roadway.

Any time you come to a place where people may cross or enter your path, or where one line of traffic meets another, you should look to the left and right sides of your vehicle to make sure no one is coming.

If you are being followed too closely by another driver, merge into a different lane. If there is no lane available for merging, wait until the road ahead is clear and slowly reduce your speed. This will encourage the tailgater to drive around you.

This sign marks a one-way road, entrance, or exit. If you are facing this sign, traffic is coming toward you. Turn around if you are driving toward this sign.

A diamond-shaped yellow sign warns of possible danger ahead. Orange signs, which are mostly diamond-shaped, are used to warn of possible dangers in or near work areas.

Any amount of alcohol acts as a depressant, slowing the function of the nervous system. It will reduce a person's alertness and ability to concentrate, increase their reaction time, and drastically reduce their coordination.

The only way to remove the impairing effects of alcohol is to give the body time to remove it from the body. Drinking coffee, physical activity, or taking a cold shower will not speed up this process. It takes about one hour to cancel the effects of one drink.

Use low beam headlights when driving in rain, snow, sleet, or fog. High beam headlights in adverse weather conditions lower visibility by reflecting off the precipitation and back into the driver's eyes.

Drivers of trucks, buses, vans, or any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

A number of drugs can impair your ability to drive, including depressant medications like tranquilizers and sedatives; over-the-counter cough syrups, cold tablets, and allergy medications (which may contain impairing substances like alcohol, codeine, or antihistamines); and illegal drugs.

Drivers must obey any instructions given by a police officer, even if the instructions contradict laws, signs, signals, or markings that would otherwise apply.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

Because large commercial vehicles have large blind spots on each side, you should avoid driving beside them for long periods of time.

The stop sign is the only eight-sided sign you will see on any roadway. When you encounter a stop sign, you must come to a complete stop. You may not proceed until the way is clear for you to completely and safely pass through the intersection.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about an upcoming winding road.

If you try to insert your vehicle between a turning truck or bus and a curb, you may suffer a serious crash. To avoid a collision, do not turn until the truck or bus has completed its turn.

If the headlights of an oncoming vehicle are blinding, glance toward the right edge of the road instead of looking directly ahead. This should keep your vehicle safely on the road until you pass the oncoming vehicle.

It is important to remember that driving is a privilege and that all drivers play a role in ensuring that everyone remains safe on the roadways. If you prove to be abusive of that privilege, the privilege may be revoked.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

When facing a green light, you must yield to pedestrians and vehicles already in the intersection. Drivers must yield to pedestrians when turning on a steady green signal.

Both hands should be placed on opposite sides of the steering wheel. This position is comfortable and promotes safe turning on high-speed roadways.

This sign indicates that the right lane ends ahead. A merging maneuver will be required for drivers in that lane.
