South Carolina CAR DMV Practice Test 3

Always turn your head to check behind your vehicle before and while backing up. Be sure the way is clear of other traffic before moving.

On a highway with four or more lanes, you must stop for a school bus loading or unloading passengers only when you are traveling behind it. You must still drive with special caution when driving near children.

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.

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming intersection.

This sign warns that there is a steep hill ahead.

Hydroplaning is caused by driving too fast on a wet road. Slow down when driving on wet pavement to prevent hydroplaning.

At an intersection where there is no stop sign or traffic signal, you should yield to a vehicle approaching the intersection from the right. However, always be prepared to yield to avoid a crash. Do this by taking your foot off the accelerator, covering the brake, and looking left, right, and left again.

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.

This sign warns that deer cross the roadway in the area. You should slow down, be alert, and be ready to stop.

Pumping the brakes is generally the best way to stop a car in an emergency. The car will stop quickly and you will also be able to continue steering.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

A double solid yellow line means that it is prohibited for vehicles traveling in either direction to cross the centerline to pass.

A round sign always indicates that you are approaching a railroad crossing.

Passing on the right is permissible only if it is possible to do so without driving off the roadway. Never pass another vehicle on the shoulder because the other driver will not expect you to be there and may pull off the road.

The exhaust system carries exhaust gas out of the vehicle and prevents fumes from entering into the passenger compartment. To prevent carbon monoxide poisoning, keep your exhaust system free of leaks. Replace all defective parts immediately.

As an increasing number of drivers populate the roadways, road rage becomes more prevalent. To help prevent road rage, a driver should use proper turn signals, obey posted speed limits, and allow plenty of travel time.

When merging into traffic, you should signal and enter at the same speed that traffic is moving. Always yield to other traffic when entering a roadway.

Even if a vehicle is properly equipped with rearview and outside mirrors, it still has blind spots that cannot be seen in the mirrors. Large trucks have much larger blind spots than most passenger vehicles.

You must stop for a school bus loading or unloading passengers if you are driving in either direction on a two-lane, two-way highway. You must also stop when approaching the bus from behind on a four-lane highway.

If there is no stop line or crosswalk, you should stop at the point nearest to the intersecting roadway where you can get a view of approaching traffic. You should not enter the intersecting roadway to gain a better view.

Low beam headlights should be used when driving in rainy or foggy weather. Even if they do little to help you see, low beams will make it easier for others to see you.

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

South Carolina has an implied consent law. By driving in the state, you automatically give your consent to be tested for levels of any dangerous controlled substance. If you refuse to be tested, your license will be suspended for six months. This is in addition to any suspension that you may receive if you are convicted of driving under the influence.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash. The speed you drive affects your stopping distance, so you should increase your following distance as you increase your speed.

Yellow signs with black markings are used to warn drivers about upcoming hazards or special conditions. Round signs are used only to warn about upcoming railroad crossings.

If your wheels drop off the roadway or pavement edge, do not attempt to turn back onto the roadway immediately. Instead, reduce your speed, check traffic, and gradually turn back onto the roadway when it is safe to do so.

Only the passage of time can remove alcohol and its impairing effects from the body.

A license to drive confers a privilege, not a right. You may keep this privilege only as long as you drive safely. Your license will be suspended if you accumulate 12 points for violations committed inside or outside of the state.

Drivers must yield the right-of-way to pedestrians who are crossing the street in any marked or unmarked crosswalk. In the interest of safety, drivers should yield the right-of-way to people crossing any street.
