Florida CDL — General Knowledge questions with answers
20 sample questions from the Florida CDL — General Knowledge question bank — each with the correct answer, a short explanation, and the section of the official handbook it comes from.
Show all 20 questions with answers
1. Your driving privilege has just been suspended. How quickly must you tell the company you drive for?
Correct answer: Within two business days
A suspension, revocation, cancellation or disqualification has to reach your employer within two business days. Convictions for ordinary traffic offenses carry their own, longer reporting deadline.
2. Which combination decides how high a person's blood alcohol concentration will climb?
Correct answer: How much is consumed, how quickly it goes down, and what the person weighs
More alcohol, quicker drinking and a lighter body each push the reading upward. A small person reaches the same concentration on noticeably less.

3. A car behind you wants to pass and, from your high seat, the road ahead looks clear. Should you wave the driver around?
Correct answer: No, never signal another driver that passing is safe
Waving someone past makes you responsible for whatever happens next, and a resulting crash can be blamed on you at enormous cost. Let other drivers decide for themselves when to pass.
4. At the scene of a crash, what is generally the right way to help an injured person?
Correct answer: Avoid moving them unless there is danger, and stop serious bleeding
Unless there is danger such as fire, do not move a seriously injured person — moving them can make an injury worse. Keep them calm and warm, stop heavy bleeding, and wait for trained help.
5. A roadside inspector places your vehicle 'out of service.' What does that mean?
Correct answer: The vehicle must not be driven until the problem is corrected
An out-of-service order means the vehicle (or driver) has a serious safety violation and may not be driven until it is corrected. Ignoring an out-of-service order brings heavy fines and disqualification.

6. How should a commercial driver approach a highway work zone?
Correct answer: Slow down, obey the reduced limit, and watch for workers
Slow down, obey the posted work-zone speed, watch for workers and sudden stops, and be ready for lane shifts. Fines for speeding in a work zone are typically increased.
7. How far ahead should a commercial driver normally look while driving?
Correct answer: About 12 to 15 seconds ahead
Looking 12 to 15 seconds ahead — about a block or more in the city and a quarter mile on the highway — lets you spot hazards early and react smoothly instead of at the last second.
8. You have stopped just past a crest where drivers cannot see you until they are nearly on top of you. How does that change where the farthest warning device goes?
Correct answer: Carry it farther back down the road, past the crest, so traffic is warned well before it reaches you
A hill or a curve that blocks the view swallows the usual spacing. Walk the farthest device back beyond the obstruction so that approaching traffic gets a warning from at least 500 feet away.
9. Why should a driver pay attention to the space above the vehicle?
Correct answer: Low clearances can strike the top of the vehicle if you do not check your height
Low bridges, signs, and wires can be lower than they look, and a loaded or air-suspension vehicle's height can change. Know your height and watch posted clearances to avoid striking overhead objects.
10. A speed limit sign is posted on the curved ramp leading off a freeway. Why should a loaded truck often travel slower than that number?
Correct answer: The posted figure is chosen with cars in mind and can be unsafe for a tall, heavily loaded vehicle
Exits and entrances are among the more dangerous places for large vehicles, especially where a ramp turns and drops at the same time. Get the speed down before you reach the curved part.
11. A CDL holder's privilege to drive a personal vehicle is revoked over traffic-law convictions. What becomes of the commercial privilege?
Correct answer: It goes as well, and no hardship permit is available for driving a commercial vehicle
Losing the personal driving privilege takes the commercial one down with it. A restricted or hardship permit cannot be used to keep working behind the wheel of a commercial vehicle.

12. Under what condition may a driver take a medicine prescribed by a physician and still operate a commercial vehicle?
Correct answer: When the physician has told the driver it will not interfere with driving safely
A drug supplied by a doctor is allowed only with that assurance behind it. Warning labels and the doctor's instructions are worth reading before a trip, because many cold and allergy remedies bring on drowsiness.

13. Objects seen in a convex ('spot') mirror on a truck appear:
Correct answer: Smaller and farther away than they really are
Convex mirrors show a wider area but make everything look smaller and farther away than it really is. A vehicle in a convex mirror is closer and larger than it appears.

14. Your right wheels drift off onto the dirt shoulder. What is the safest way to get back on the road?
Correct answer: Ease off the gas, keep straight, slow down, then steer back gently
Stay off the brake, ease off the accelerator, and keep the vehicle straight until it slows. When it is safe and your speed is down, steer back onto the pavement gently — do not jerk the wheel.
15. What can happen to a CDL holder who repeatedly texts or uses a handheld phone while driving a CMV?
Correct answer: Fines and, after multiple offenses, disqualification of the CDL
Federal rules treat texting and handheld phone use as serious violations. They carry fines for the driver and the employer, and two or more offenses within a set period lead to disqualification of the CDL.

16. Which vehicles are generally required to stop at every railroad crossing, even when no train is coming?
Correct answer: Buses carrying passengers and trucks hauling placarded hazardous materials
Certain vehicles — such as buses carrying passengers and trucks placarded for hazardous materials — must stop at railroad crossings, check that the way is clear, and then cross without shifting gears.
17. In cold weather, how can a driver get an early clue that the road may be icing over?
Correct answer: Watch for ice building up on mirrors, wipers, or antennas, and for spray from other tires stopping
Ice forming on mirror arms, wipers, or the antenna is a warning that surfaces are freezing. When tire spray from other vehicles stops even though the road looks wet, the water may be turning to ice — slow down.
18. Where possible, how should a driver position a large vehicle when parking it?
Correct answer: So that leaving the space can be done by pulling forward
Backing is the most dangerous thing a large vehicle does, because so much of the path behind is hidden. Picking a spot you can drive straight out of removes that risk before it arises.

19. Compared with a fully loaded truck, an empty truck often needs:
Correct answer: A longer stopping distance because of reduced traction
Empty trucks can take longer to stop because their brakes and tires are designed to grip best under a heavy load. With little weight, the tires have less traction and can lock up more easily.
20. On a long mountain downgrade you pass a sign posting a maximum safe speed. How should you treat that figure?
Correct answer: As a limit you must never go above on that grade
A posted safe speed on a grade is a ceiling, not a target to reach. Signs that give the length and the steepness of the hill deserve the same attention while you plan the descent.
