South Carolina CAR DMV Practice Test 22

You must never drive so slowly that you interfere with other cars or trucks that are moving at a normal speed.

Driving at night is more dangerous than driving during the day for several reasons. It is harder to see in the dark, you may be temporarily blinded by the glare from other vehicles' lights, and there are likely to be more drivers on the road who are tired or under the influence.

To avoid being blinded when driving at night, do not look directly at the headlights of oncoming cars. Instead, look toward the right edge of the road until the oncoming driver has passed.

If one or more of your wheels run off of the pavement, grip the steering wheel firmly and slow down by taking your foot off the accelerator. Do not attempt to cut back sharply onto the pavement. Instead, look to see that the road is clear, then move slowly back onto the highway.

The maximum speed limit in an urban or residential area is usually 30 miles per hour.

When passing a bicyclist, slow down and give them as much space as you can. Bicyclists have much less protection than drivers of motor vehicles and they should not be crowded. Passing a bicycle too quickly can shift the bicyclist off-course.

You should always reduce your speed and use extra caution when children are in the vicinity. They may fail to understand the danger and may run out in front of you without looking.

Not getting enough sleep is a cause of poor driving behavior. Just like drugs and alcohol, sleepiness slows reaction time, decreases awareness, and impairs judgment.

It is unlawful to drive at night using only your parking lights. You must use your headlights when driving in lowered visibility.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

The speed at which you are traveling affects almost everything else that can happen to you in a car. You must always comply with posted speed limits. Heavy traffic conditions and poor weather conditions require a slower speed.

A red traffic light means that you must stop before entering the intersection. You must at any stop line and before entering any crosswalk.

Using a cell phone (including a hands-free phone) or any kind of audio device (including a radio or CD player) can be a dangerous distraction and contributes to the risk of a crash.

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.

This sign indicates that you are approaching a railroad crossing. You must look, listen, slow down, and prepare to stop. Wait for any trains to pass before you proceed.

Two solid yellow lines down the center of a two-way road mean that neither lane of traffic may cross the lines, unless they are turning off of the roadway. A driver can cross double yellow lines when turning into or out of a driveway or entrance to a business. No passing is allowed over a solid yellow line.

Drugs (including illegal, prescription, and over-the-counter medications) can affect your brain function and impair your ability to drive safely. Combining alcohol with other drugs will increase the risk of a crash.

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

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This sign tells drivers the direction in which they must drive when turning onto a one-way street.

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.

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.

While airbags provide supplemental protection for adults in the event of a crash, they pose a severe safety risk for children. Anyone age 12 or under should sit in the back seat of a vehicle with airbags.

You should steer with one hand only when backing up or operating a vehicle control. Your hands should be placed on the outside of the steering wheel on opposite sides with your thumbs facing up.

A distraction when driving is anything that takes your attention away from driving. Driver distractions may occur anytime and anywhere. Distracted driving can cause collisions, resulting in property damage, injury, and death.

You should slow down at the first sign of rain, snow, or sleet, all of which can create slippery road conditions. When conditions on the road are less than ideal, safety may require that you drive more slowly than the posted speed limit.

After a collision, if no one has been injured or killed and you can safely do so, you should move your vehicle out of the traffic lane.

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.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

When stopped for a traffic violation or at an equipment check, the driver is responsible for producing their license, proof of registration, and proof of insurance. Drivers are required to have all three of these documents in a vehicle when it is being driven.

This sign warns drivers that the divided highway ends ahead.
