Kentucky CAR DMV Practice Test 23

Even when you signal, you should not assume that the space you want to occupy is free or that other drivers will give you the right-of-way.

A warning sign is usually yellow with black markings. This sign warns that the number of lanes ahead is reduced and that traffic will need to merge to the left.

A flashing yellow light means that you should slow down, check for cross traffic, and proceed with caution.

When driving on an interstate highway, be aware of upcoming on-ramps. When traffic permits, move out of the right-hand lane to allow vehicles to enter from the on-ramps to your right.

When driving too quickly in wet conditions, your tires may lose all contact with the road surface. Loss of traction will cause the vehicle to ride on top of the water, which is called "hydroplaning." The best way to prevent this from happening is to drive more slowly in rainy or wet conditions than you would when driving during ideal weather conditions.

Make room for vehicles entering interstate highways. Whenever possible, change lanes to allow those entering to merge smoothly and safely.

A three-sided yield sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed. In this case, you do not have the right-of-way.

The law requires you to turn off the engine and remove the key from the ignition when leaving a vehicle. Always lock your vehicle when leaving it, even if you are only going to be away for a short period of time.

White lines separate lanes of traffic moving in the same direction. You may cross a dashed white line to pass or change lanes if it is safe to do so.

Large trucks take longer to stop than other vehicles traveling at the same speed. The average passenger vehicle traveling at 55 mph can stop within 400 feet. However, a large truck traveling at the same speed can take almost 800 feet to stop.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This sign tells drivers that it is prohibited to make a U-turn.

Yellow lines separate traffic moving in opposite directions. Dashed lines on the pavement indicate that passing is permitted when safe.

Yellow lines separating lanes of traffic indicate that traffic is moving in opposite directions. Double solid lines indicate that passing is not permitted from either direction.

Keep a space between your vehicle and parked vehicles. A person may step out of a parked vehicle or out from between the parked vehicles without looking. A driver may begin moving their vehicle before realizing you are there.

When turning left from a one-way street onto another one-way street, you should begin the turn from the far left lane.

If there are oncoming vehicles to your left and a row of parked vehicles to your right, the best thing to do is to split the difference. Steer a middle course between the oncoming cars and the parked cars.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

You need a longer distance to stop your vehicle on a slippery road than you do on a dry road. Maintain an increased following distance when driving on slippery roads.

When a vehicle makes a turn, the rear wheels follow a shorter path than the front wheels. The longer the vehicle, the bigger the difference between the paths of the front and rear wheels. Therefore, long trucks often have to swing wide to complete a right turn.

The only way to sober up after drinking alcohol is to allow time for your body to eliminate the alcohol in your system. Nothing you can do, including eating and drinking, can accelerate this process.

This sign informs drivers that they are leaving a divided roadway and approaching a two-way highway.

Hydroplaning occurs when there is standing water on a roadway. At speeds up to 35 mph, most tires will channel water away from the tire. As your speed increases past 35 mph, tires cannot channel the water as well and your tires may start to lose contact with the road and ride over the water like a set of water skis.

Before you return to the driving lane when completing a pass, be sure there is a safe gap between your vehicle and the passed vehicle. When you can see both headlights of the vehicle in your rearview mirror, it is safe to return to the driving lane.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign tells drivers to prepare to allow traffic to safely merge from the right.

Driving during the first half hour of rainfall is dangerous because roadways become extremely slippery when the water mixes with oil and other chemicals on the road surfaces that have not yet washed away. Use extra caution when driving on slippery roads.

You should be extra careful when turning and stopping during the first half hour of rain. At this point, the oil from cars has not yet washed off the pavement and could be forming a slippery mixture with the rain.

Drivers making left turns must yield to oncoming traffic that is traveling straight. Drivers must always yield to pedestrians.

Before changing lanes, check for drivers trying to pass you who may be trying to enter the same lane as you. Look over your shoulder to check your blind spot. You should never attempt to pass or otherwise change lanes in an intersection.

This sign warns that the road ahead becomes slippery when wet.

When approaching a railroad crossing, you must look, listen, slow down, and prepare to stop. Let any trains pass before you proceed.

A flashing red traffic light means the same thing as a stop sign. When arriving at an intersection with a flashing red light, you must come to a full stop and proceed when it is safe to do so.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

This sign warns a driver of a change in direction or a narrowing of the road. A driver may find several of these signs on the outside of a sharp curve or on approaches to a narrow bridge.

If you want to enter the freeway but do not see a space for your vehicle in traffic, slow down on the ramp to wait for a gap. Do not drive to the end of the ramp and wait for a gap or you will not have enough room to accelerate to the speed of traffic before entering the roadway.

To prevent hydroplaning, lower your speed in response to wet roads and keep your tires in good condition. If you detect a loss of control, take your foot off the gas, do not apply the brakes, maintain the direction of the vehicle, and allow the vehicle to slow to a manageable speed.

Use your low beam headlights when driving in foggy, snowy, or rainy conditions. Light from high beam headlights will reflect back, causing glare and making it even more difficult to see ahead.

Warning signs are usually yellow with black markings. This sign indicates that there could be traffic merging from the right, so drivers should prepare to allow traffic to safely merge.

Signal 100 feet before beginning a turn. Signaling in advance allows other drivers plenty of time to prepare for your vehicle's movement.

Before changing lanes, signal, look in all your mirrors, and look over your left or right shoulder to make sure the lane next to you is clear. Looking over your shoulder is a way to check your blind spot to be sure there is no vehicle, motorcycle, or bicycle traffic in the next lane.

You should adjust your speed to travel smoothly with the other traffic on a roadway (provided that the other traffic is driving within the posted speed limits). Remember that vehicles moving in the same direction at the same speed cannot hit each other. Crashes involving multiple vehicles often happen when some vehicles are traveling at different speeds than others.
