Arkansas CAR DMV Practice Test 18

When entering the interstate on a short entrance ramp where there is no acceleration lane, speed up only after you have identified a gap in traffic. In general, you should be stopped while waiting for a gap to appear.

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

Fatigue causes errors related to speed and distance, increases your risk of being in a crash, and causes you to take more time to make decisions. When you are fatigued, you could fall asleep behind the wheel and crash, injuring or killing yourself or others.

Warning signs are usually yellow with black markings. This sign warns drivers that they are arriving upon a fork in the road and they must bear either right or left.

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.

Low beam headlights should be used in fog, rain, and snow. The light from high beams will reflect back to the driver under these weather conditions, causing a glare that will make it difficult to see ahead.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

When entering any roadway, you must be aware of traffic conditions. Use your side mirror and look over your shoulder to help you see and anticipate traffic when entering a freeway.

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.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

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.

Arkansas law requires drivers to turn on their headlights when windshield wipers are needed. Low beam headlights should be used under rainy, snowy, or foggy conditions.

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

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. There may be an upcoming change in traffic direction, a steep downgrade, or another potentially hazardous situation that requires action on the part of the driver.

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 alerts drivers to the right lane ending and tells them to prepare for potential merging traffic.

Adjust your inside rearview mirror so you can see the entire rear window from the driver's seat. You should only have to move your eyes, not your head, to use this mirror.

Rubbernecking (the practice of slowing down to look at collisions or other out-of-the-ordinary things) contributes to traffic congestion and should be avoided.

When parking uphill on a road that has a curb, your wheels should be turned away from the curb. When parking uphill on a street without a curb or when parking downhill, your wheels should be turned toward the curb or edge of the road.

If a line separating lanes of traffic is solid, drivers may not cross the line to pass or change lanes. White lines separate lanes of traffic moving in the same direction.

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.

When driving in a work zone, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment, workers, and other vehicles. Increase your following distance and do not tailgate.

Always obey posted speed limits. Check your speedometer often to ensure you are driving within the legal speed limit.

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.

This is a low clearance warning sign. It indicates the distance from the road surface to the bottom of a bridge or overpass (in this case, 12 feet, 6 inches).

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