Mississippi CAR DMV Practice Test 24

Yellow lines are used to separate traffic moving in opposite directions. Solid lines indicate that drivers are not permitted to pass.

When changing lanes, you must be sure that there are no vehicles in the space you want to enter. Check for other vehicles behind and to the side of your vehicle by checking your mirrors and blind spots. Always use the proper turn signal before changing lanes to allow surrounding vehicles time to react to your movements.

Use low beam headlights when driving in fog, rain, or snow. High beams may reflect off of the weather and make visibility even poorer.

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

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.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

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.

Work zones on highways have become increasingly dangerous places for both workers and drivers. When approaching a work zone, watch for materials such as cones, barrels, signs, large vehicles, and workers in brightly colored vests to warn you and direct you.

You must yield the right-of-way to any emergency vehicle that is using its siren and lights. Drive to the right edge of the road and stop until the emergency vehicle has passed. If you are within an intersection, drive through the intersection first and then stop.

Where there are both solid and dashed yellow lines between lanes of traffic, only traffic directly next to the dashed line may cross the centerline to pass. Drivers next to the solid line may not pass.

The only way to remove the effects of alcohol from the body is to let time pass. Eating, drinking coffee, or taking a shower will not speed up this process.

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

When driving in a work zone, adjust your speed for the traffic conditions and don't follow other vehicles too closely. Be attentive to workers and machines in the work zone.

Yellow lines mark the center of a road used for two-way traffic. A solid yellow centerline indicates that drivers may not cross the line to pass. A broken yellow centerline indicates that drivers may cross the line to pass, but only if passing would not interfere with traffic.

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

This sign warns of a winding road ahead.

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.

This sign is posted on one-way streets and other roadways where a driver is not allowed to enter. A driver may see this sign if attempting to enter an expressway ramp in the wrong direction.

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.

Legal medications, both prescription and over-the-counter, can potentially impair your ability to drive. Always consult with your doctor or pharmacist if you have questions about how a particular drug or drug combination will affect your ability to drive. You should particularly make a point of talking with your doctor if they give you a prescription for a tranquilizer or sedative.

This sign warns of of an approaching traffic signal.

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.

Large vehicles require longer distances to stop and accelerate than smaller vehicles do. Making a sudden stop in front of a large vehicle is dangerous because the other driver may not be able to stop in time to avoid a collision.

You must not pass a vehicle that is stopped at a crosswalk. There may be pedestrians crossing the street that you cannot see. Instead, stop, proceeding only after all pedestrians have crossed.

Slow down and proceed with caution if you see animals that are standing near the roadway. They may unexpectedly bolt or change direction at the last moment. Some animals travel in packs, so there may be more animals just out of sight that are also near the road.

If your vehicle begins to skid, stay off the brakes. Continue to correct your steering until the vehicle is back under your control and moving safely down the road.

The term “distracted driving” refers to driving while anything takes your eyes, hands, or mind away from the task at hand. Distracted driving is the most common contributing factor to reported traffic collisions. Distractions of any sort cause drivers to miss key visual and audio cues needed to avoid a crash.

When driving in heavy rain at speeds as low as 30 mph, your tires may lose all contact with the road and instead ride up on a layer of water above the surface of the road. This is called "hydroplaning." If your vehicle starts to hydroplane, slow down gradually and do not apply the brakes.

This sign prohibits right turns. It is illegal to turn right at an intersection where this sign is posted.

An octagonal sign always means stop. When approaching a stop sign, you must come to a complete stop at the marked stop line and proceed only when it is safe to do so. If there is no stop line, stop before the crosswalk. If there is no crosswalk, stop before the intersection at a point from which you can see oncoming traffic.
