Florida CAR DMV Practice Test 18

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign tells drivers that they are approaching a school zone and that they should slow down and watch for children.

Alcohol reduces your reaction time, reduces your ability to see clearly, changes your judgment of speed and distances, reduces your ability to recover from the glare of headlights, and often reduces your inhibitions and makes you more likely to take risks.

This sign indicates that a roundabout is ahead. Enter a roundabout at a low speed and yield to existing traffic.

Entrance ramps for highways often have acceleration lanes. When merging with traffic from an acceleration lane, you should put your signal on, look for an opening in traffic, accelerate up to the speed of traffic, and merge into an opening in traffic.

When turning left at a traffic signal, you must yield the right-of-way to pedestrians and oncoming traffic.

This sign indicates that the road ahead curves to the right.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

To check your blind spot, glance over your shoulder in the direction that you want to move.

Octagonal signs are always stop signs. Come to a complete stop when approaching a red, eight-sided sign.

Reduce your speed when roads are snow-covered or icy. Doing this and increasing your following distance are the most important techniques for avoiding crashes under snowy or icy conditions.

At dusk or on overcast days, you must turn on your headlights. Dim your lights to their low beam setting when within 1,000 feet of an approaching vehicle and when within 500 feet of a vehicle that you are following. When driving in poor weather, always use your low beams.

A steady downward green arrow over a traffic lane means you may use the lane indicated.

Because of their size, trucks need longer distances to stop than smaller vehicles do.

This sign warns of two-way traffic ahead.

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.

Any medication could potentially affect your ability to drive. Be sure to ask your doctor or pharmacist about the effects your prescription may have on driving. Read the labels on over-the-counter medicines to determine if their side effects can impair your driving.

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.

If another vehicle is approaching you head-on in your lane, you should first honk your horn to attract attention. If the other driver does not move over, try to escape to the right. If you swerve left and the other driver corrects at the last instant, you will still crash. If a collision is unavoidable, brake firmly and steadily. Every mile per hour you slow down will reduce the impact.

This sign warns that there is a steep hill or downgrade ahead.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

A flashing red traffic light has the same meaning as a stop sign. You must stop, yield the right-of-way, and go once it is safe.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Use your turn signal to let other drivers know you plan to change lanes. Check for other drivers who also may be moving into the same lane.

If a traffic light at an intersection is not functioning due to a power outage, yield to other drivers in the same manner as you would when approaching a four-way stop. When it is your turn, proceed through the intersection with caution.

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning devices, such as gates or flashing lights. Not all railroad crossings are equipped with such devices. It is against the law to drive around lowered railroad crossing gates.

Alcohol is a depressant drug that slows the activity of the brain and reduces the skills that you need for safe driving. Drinking alcohol results in slowed reaction time and impaired judgment.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that a traffic signal is ahead and drivers should prepare to react to a yellow or red light.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.

Compared to signs and other roadside objects, pedestrians are hardest to see at night.

If you stop along the road at night, turn on your emergency flashers and leave your low beam headlights turned on. Be sure that other road users will be able to clearly see your vehicle.

When entering a freeway, use the on-ramp to accelerate to the speed of freeway traffic so you can blend in smoothly and safely. Entering traffic must yield to traffic already on the freeway.

Railroad crossing warning signs are used to warn drivers of the possibility of a train. Drivers should obey all railroad crossing warning signs and never go around barriers or disregard the warning sign.

This sign (with the arrow below) indicates the location of a bicycle crossing/path. Drive with caution around this sign because bicycles likely regularly cross or ride beside traffic in the area.

Alcohol is a depressant that negatively affects judgment, vision, concentration, understanding of reality, and reaction time. It is never safe to consume alcohol in any amount before getting behind the wheel of a car.
