Florida CAR DMV Practice Test 1

Traffic signals are placed at intersections to keep traffic moving and to help prevent crashes. Drivers, pedestrians, and cyclists must obey these signals, except in instances when an officer is directing traffic.

Highway markings provide information for drivers. Markings help drivers correctly position their vehicles on roadways, inform drivers of safe passing zones, and warn drivers about upcoming conditions.

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

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

White lines are used to separate traffic moving in the same direction. Solid lines indicate that drivers are not permitted to pass.

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

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign indicates that drivers are approaching a steep hill and should prepare to adjust their speeds to continue to drive safely.

The faster you drive on a wet roadway, the less effective your tires will be at wiping the water from the road. If your speed becomes excessive enough, your tires will lose their grip on the road entirely and you will begin to hydroplane (that is, to slide down the road on a film of water).

To prevent drowsiness on long trips, you should schedule regular stops. Give yourself time to rest and stretch, even if you are not feeling tired.

When the road is wet or slippery, when you cannot see well, or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.

The combination of alcohol and drugs, in some cases, can increase the effects of both the drugs and alcohol. It can be unsafe to drive after consuming either alcohol or drugs and is even more dangerous after combining them.

"Highway hypnosis” happens when you stare straight ahead at the roadway for long periods of time and stop actively scanning ahead, behind, and around your vehicle. This can lead you to zone out, making you very likely to crash into traffic slowing or stopping ahead of you.

A red traffic light means that you must stop before entering the intersection. You must at any stop line and before entering any crosswalk.

A flashing yellow light at an intersection means "caution." If you approach such a light, slow down, look, and proceed with care.

Consuming both alcohol and another drug may enhance the effects of both. For example, taking one drink when you are also using a cold remedy could affect you as if you have had several drinks.

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.

This sign warns that there is a steep hill ahead.

Never make last-minute turns. If you reach an intersection where you wish to turn but you are not in the proper lane to make the turn, drive to the next intersection and then make the turn from the proper lane.

This sign indicates that the road ahead winds with a series of turns or curves.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. Continue scanning the road, checking your mirrors, and looking at the instrument panel at regular intervals. Developing these safe habits will keep you attentive as a driver.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

If you follow too closely and the vehicle in front of you slows or stops suddenly, you may not have enough time to avoid a collision.

Construction, maintenance, and emergency operations signs are generally orange with black symbols.

When entering a roadway from a driveway or private road, you must yield the right-of-way to pedestrians and traffic on the roadway.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

If a green arrow is shown with a red light, you can only drive in the direction of the arrow and only if the intersection is clear.

This sign indicates where a lane is reserved for the exclusive use of left-turning vehicles from either direction. Such a lane may not be used for passing or for through-traffic.

Pennant-shaped warning signs like this are only used to indicate a no passing zone.

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

Drivers must come to a complete stop when approaching a school bus that is stopped with its lights flashing. Failure to stop until the lights stop flashing will result in a fine of at least $165. Passing a bus on the side where its door is located will result in a fine of at least $265. Additional penalties will apply.

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.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

A steady red traffic light indicates that drivers must come to a complete stop. Driving through a red light is against the law and is extremely dangerous. Drivers may turn right on a steady red light if there is no sign prohibiting a turn on red.
