Florida CAR DMV Practice Test 20

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential bicycle cross traffic.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

One situation where it is appropriate to use your horn is if you lose control of your vehicle. In this case, sound your horn to alert other drivers.

Always signal for an appropriate amount of time before making a lane change or exiting a freeway. Before you make any move to the right or left, quickly turn your head and look over your shoulder to see if your blind spot is clear.

Unless otherwise posted, the speed limit on streets and highways is 55 mph. If a posted sign indicates otherwise, follow the speed limit on the posted sign.

You drive defensively when you identify dangerous driving situations and take action before an accident occurs. Defensive driving helps prevent conflicts with aggressive, offensive, discourteous, careless, inattentive, impulsive, ignorant, or intoxicated drivers or pedestrians.

If you are being followed too closely on a multilane roadway, you should move into the lane to your right when the path is clear. On multilane roads, the far left lane is intended for use by faster vehicles passing slower vehicles.

When changing lanes, it is important to check your blind spots. Do this by looking over your shoulder toward the next lane. Do not rely only on your mirrors.

Signs providing information about destinations are green with white letters or symbols.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

Alcohol reduces all of the important skills necessary to drive safely, such as judgment, reaction time, vision, and concentration. Alcohol is absorbed into the lining of the stomach and then passes directly into the bloodstream and reaches your brain within minutes after consumption. A person’s judgment is the first thing affected after drinking an alcoholic beverage.

The ability to drive safely is dependent on the driver being in good physical condition. Driving can be impaired by alcohol, legal and illegal drugs, and being drowsy.

These signs indicate that the road curves to the right ahead and that drivers should slow down to the safe speed indicated (in this case, 35 mph).

Always signal your intentions when changing lanes, turning, or pulling away from a curb. Do not allow yourself to become lazy and form the bad habit of not following this law.

Some restricted parking areas are designated by painted curbs. Curbs painted yellow may indicate a loading zone, a fire hydrant, or other restrictions prohibiting parking.

At night, your field of vision is reduced. To make sure you are able to react to hazards on the roadway, always use appropriate headlights. Drive slowly enough that you are able to stop within the distance that you can see ahead.

This sign indicates that there is merging traffic entering from the right.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.

Stop lines are solid white lines painted across traffic lanes at intersections and pedestrian crosswalks. They indicate the exact location at which approaching drivers must stop.

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.

Wet roadway surfaces can be dangerously slick, especially immediately following a rainfall. When you are driving on wet roads, your vehicle is traveling on a thin layer of oil, dirt, and water. Slow down when there is heavy rain, standing water, or slush on the road to reduce the risk of your wheels losing traction on the slick surface.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

In snowy weather, keep your windshield and mirrors clear. Increase your following distance when driving in wet and cold weather because a slippery road surface will increase the distance needed for your vehicle to stop.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

Certain offenses committed while driving will count against the driver in Florida's system of suspending driver licenses. If a driver accrues 24 points or more within a 36-month period, their license will be suspended for one year.

Any driver or pedestrian approaching a railroad crossing must stop within 50 feet, but not less than 15 feet, from the nearest rail of the railroad when warning lights are flashing, crossing gates are lowered, or drivers are otherwise instructed to stop.

If a load extends more than four feet past the rear of a vehicle, it must be marked by a red flag when being transported during the day in clear weather. The flag should be 18 inches square. Red lights and reflectors are required when transporting the load in times of limited visibility.

If a driver is towing something behind their vehicle, they must ensure that the drawbar or towing connection is strong enough to pull all of the towed weight safely. If the towing connection is a rope, cable, or chain, the driver should attach a square, 12-inch white flag. Unless the towed object is difficult to take apart, the towing connection should be no more than 15 feet long.

Upon striking an unattended vehicle, stop and try to locate the owner. If you cannot find the owner, leave a written notice containing your name, your address, and the circumstances of the accident.

Regulatory signs are often rectangular and white with black markings and are used to indicate what things a driver must or must not do in a designated area. They may display speed limits, prohibit passing or turning, or clarify any other driving regulation.

The average person’s body will process about one alcoholic drink in one hour. However, many factors play a part in determining how impaired a person will become when consuming alcohol, including the amount of alcohol consumed, how fast it is consumed, and a person’s body weight, food intake, and general health.

This sign warns that the road is slippery when wet.

The most important thing to remember about driving in curves is that your vehicle’s inertia may make it difficult to turn. To maintain control, it is essential that you slow down before entering the curve.

Do not stop at an accident scene unless you are involved or emergency help has not yet arrived. Keep your attention on your driving and keep moving, watching for people who might be on or near the road. Never drive to the scene of an accident, fire, or other disaster just to look.
