Not quite. The answer is All of the above

1) Do not cut off a truck in traffic or on the highway to reach your exit or turn. Take a moment to slow down and exit behind a truck – it will only take a few extra seconds. 2) Do not linger alongside a truck when passing. Always pass a tractor-trailer completely and always on the left side. If you linger when passing any vehicle, your position makes it impossible for the trucker to take evasive action if an obstacle appears in the road ahead. 3) Tailgating a truck or car is dangerous because you take away your own cushion of safety if the vehicle in front of you stops short. When following behind a truck, if you can’t see the truck driver’s outside mirrors, there is no way the truck driver can see you. 4) Never underestimate the size and speed of an approaching tractor-trailer. Because of its large size, a tractor-trailer often appears to be traveling at a slower speed than it is.

Not quite. The answer is All of the above

If you are driving, check the label before you take a drug for warnings about its effect(s). If you are not sure whether it is safe to take the drug and drive, ask your doctor or pharmacist about any side effects. Drugs taken for headaches, colds, hay fever or other allergies, or those to calm nerves can make a person drowsy and can affect his or her driving. Other prescription drugs can affect your reflexes, judgment, vision, and alertness in ways similar to alcohol.

Not quite. The answer is all of the above.

If you are stopped by law enforcement, you will be required to provide your valid driver license, proof of insurance, and your vehicle registration. If you do not comply, you may be subject to a fine or arrest.

Not quite. The answer is parental consent

If you are under the age of 18 and wish to obtain a learner permit or driver license, you must have a parental consent form signed by your parent or guardian.

Not quite. The answer is right lane

On a road with two or more lanes traveling in the same direction, stay in the right lane except to pass. On a road with three or more lanes traveling in the same direction, stay as far to the right as possible.

Not quite. The answer is a sibling

If you hold a provisional license and are between 16 1/2 and 20 years of age, you may carry one member of your immediate family, a licensed driver 21 years of age or older, or both as passengers.

Not quite. The answer is (a) your driving is visibly impaired

In any US state, you can be charged with driving under the influence (or whatever the equivalent term is in that state) if your driving is visibly impaired by any substance. However, there is still debate over what minimum blood tetrahydrocannabinol (THC) level should be considered evidence of driving under the influence. As of 2023, 14 states enforce zero tolerance of blood THC even for adult drivers. Five states have set numerical limits on blood THC; typically, 5 nanograms or more per milliliter of blood constitutes being under the influence. Other states have no policies on blood THC.

Not quite. The answer is the motorcycle needs the full width of the lane.

Motorcycles need a full lane width to operate safely, just like other vehicles. You should never drive alongside a motorcycle even if the lane is wide and the motorcyclist is riding to one side.

Not quite. The answer is rear-end collisions.

Always keep at least a two-second following distance between you and the vehicle ahead. When the weather is bad or the pavement is slippery, you should double that amount. On interstates, most crashes are rear-end collisions, often caused by tailgating at high speeds.

Not quite. The answer is No-Zones

Trucks and buses have blind spots called No-Zones. No-Zones are the areas around trucks and buses where smaller vehicles may disappear into blind spots. These areas can be so close that they restrict the truck or bus driver's ability to stop or maneuver safely.

Not quite. The answer is To warn a pedestrian, cyclist or the driver of another vehicle in the event of an emergency

Sound your horn only to warn a pedestrian, cyclist or the driver of another vehicle in the event of an emergency. Never use the horn in a posted “Quiet Zone” unless in an emergency. Do not use your horn to alert a motorist, cyclist or pedestrian of your approach in a non-emergency situation. A loud horn can cause a cyclist to lose control.

Not quite. The answer is All of the above

You must also be aware of potential distractions and impairments: 1) Alcohol, drugs, and even some medications can degrade your driving abilities. 2) Listening to extremely loud music or using devices such as cell phones, GPS, and intercoms can also affect your focus when driving. 3) Adjusting electronic controls and features of your vehicle can be distracting and quickly degrade your ability to scan for hazards and react to them. 4) Emotional and physical states such as fatigue, anger, illness, stress, and fear can also impair your driving skills.

Not quite. The answer is your vision is already restricted.

Drinking alcohol and driving at night is especially dangerous because your vision is already restricted since it is dark out and more difficult to see.

Not quite. The answer is Car B

Trucks have large blind spots, called No-Zones. Cars traveling directly behind or beside a truck can often be completely hidden from the driver. You could be driving right beside a truck and not be seen. Remember, if you can't see the driver's face in the driver's side mirror, the driver probably can't see you. Here, Car A should be visible through the truck's windshield, and Car C should be visible in the truck's right side mirror. But Car B is unlikely to be visible to the truck driver.

Not quite. The answer is All of the above.

Once you drink alcohol, it enters your bloodstream and starts affecting all of your bodily processes, such as coordination, self-control, and reaction time. The only "cure" to alcohol's affect on your brain is to wait until it exits your bloodstream.

Not quite. The answer is 10

Before you can obtain a full driver license, you must have previously completed at least 10 hours of night driving under the supervision of a licensed driver who is at least 21 years old.

Not quite. The answer is stop and remain stopped until all people have cleared the roadway.

Where there are school buses, there are usually children. Children are likely to do something unexpected, so be prepared. When you come to a school or church bus that has stopped to load or unload passengers, you must stop. By law, you must remain stopped until all people are clear of the roadway and the bus is in motion.

Not quite. The answer is wait for a day or two.

The more alcohol that gets into your body to make you intoxicated, the longer it will take your liver to break it all down. The liver can break down about one standard drink (one ounce of hard liquor, a one-half glass of wine, or a 12-ounce can of beer) per hour. If you consume a great deal of alcohol, it can take as long as a day or two for your body to fully recover.

Not quite. The answer is a school zone.

This pentagonal (five-sided) sign indicates a school zone.
