#1. To make sure you are not driving in a truck's blind spot, you should:
If you cannot see the driver’s face in his side-view mirror, he cannot see you. Being able to see the rearview mirrors of the truck or bus allows the driver of the larger vehicle to see vehicles behind or beside them.
Position your vehicle so the driver can see it in the side mirrors.
#2. A police officer is directing you to do a U-turn against existing signs. What should you do?
It is important to obey the orders of a police officer, firefighter, highway authority official or uniformed adult school crossing guard who is directing traffic or performing his or her official duties .
Also, obey special signs or instructions from workers (flaggers) in work zones.
#3. If driving during foggy weather, a driver should turn on the vehicle's high-beam headlights to increase the field of vision.
Turn on your low beam lights when you encounter fog, dust, heavy rain or snow. Do not use your high beam because the light will be reflected into your eyes.
#4. You are within an intersection waiting to make a left turn. The traffic signal light turns red. What should you do?
If you are within the intersection, continue through carefully. Do not back up or block the intersection.
#5. All the following is true about motorcyclists, except:
Because of their size and vulnerability in a crash, it is important for a driver to pay special attention to motorcycles. The failure of motorists to detect and recognize motorcycles in traffic is the most common cause of motorcycle crashes. Due to their small size, motorcycles may be difficult to see and motorists tend to underestimate their speed. A driver should expect to see motorcycles in traffic at any time, not just in the spring and summer. Drivers involved in crashes often report not seeing the motorcycle or seeing it too late to avoid a collision.
#6. What does drive within the range of your headlights mean?
Make sure you can stop within the distance you can see ahead (the distance lighted by your headlights). This is called driving within the range of your headlights.
#7. If there is an oncoming vehicle in your lane, you should:
When a vehicle is approaching head-on in your lane, slow down immediately. Sound your horn. Keep to the right even if this means running off the road.

Remember, you can be convicted of Driving Under the Influence (DUI) even if your Blood Alcohol Concentration (BAC) is less than .08 percent and your driving ability is impaired.
#9. You can park and leave your car:
You may not park your car in front of a public or private driveway, within 15 feet of a fire hydrant, or on a bridge. The distance you must keep from a traffic control signal is more than 30 feet. (Meaning, parking 50 feet from a traffic-control signal is allowed).
#10. Which of the following vehicles must always stop before crossing railroad tracks?
Be prepared to stop for vehicles that must stop at crossings, such as school buses, motor vehicles carrying passengers for hire or vehicles transporting explosives or hazardous materials.
#11. You meet a school bus traveling in the opposite direction on a divided roadway with two lanes. The bus is displaying alternately flashing red lights. What should you do?
When a school bus is traveling on a two-lane roadway and is stopped to pick up or drop off pupils, the vehicles in all lanes of traffic must stop. Vehicles should stop at least 20 feet before reaching the school bus to allow pupils to cross the roadway safely.
#12. Vehicles in a roundabout always travel in one direction.
All vehicles in the roundabout travel in one direction (counterclockwise).
#13. When making a left or right turn in a business or residential district, you should start using your turn signal:
In a business or residential area you must give a continuous turn signal for at least 100 feet before turning. In other areas the signal must be given at least 200 feet before turning.
#14. What do the light gray areas in the picture mark?
Turn your head before changing lanes, because your mirrors have blind spots. These blind spots can hide a motorcyclist or a bicyclist. Do not drive in another driver’s blind spot.
#15. Assuming you are traveling 35 mph and suddenly need to stop. How far will your car approximately go during 1 second?
If your speed is 35 mph, your car will travel 52 feet in one second.
#16. Which pavement marking separates traffic traveling in opposite directions?
Yellow lines mark the center of a road used for two-way traffic. Broken yellow lines indicate that passing is permitted.
#17. If you are involved in a traffic crash and someone is injured, you should:
Help any injured person if necessary or requested. First, protect the person from traffic, then cover the injured person for comfort and to avoid shock. Do not move an injured person unless absolutely necessary. Do not attempt to give first aid unless you have been trained in it. Call 911 immediately.
#18. When should you NOT pass another vehicle?
DO NOT overtake if there is any doubt, or where you cannot see far enough ahead to be sure it is safe.
#19. Why is it important not to drive with a defective muffler or exhaust system?
Carbon monoxide is deadly. It is found in fumes produced any time you burn fuel in your vehicle. It is recommended you have a mechanic check the exhaust system of your vehicle every year and never run your vehicle inside a garage that is attached to your house.

Teen drivers must earn the right to move from one phase to the next, based on experience and their driving behavior.
Phase I: Instruction Permit Phase – Restrictions
With an instruction permit you may start driving together with a parent or any adult who is 21 years or older, holds a valid driver’s license, and has at least one year of driving experience.
The permit is valid for two years if you are under 18 years (one year if you are 18 years or older).
The instruction permit comes with the following restrictions:
General night curfew.
A permit holder cannot drive Sunday-Thursday between 10 p.m. and 6 a.m., and Friday-Saturday between 11 p.m. and 6 a.m. (local ordinances may set different curfews).
Number of passengers is limited.
The number of passengers in the vehicle is limited to one in the front seat and the number of safety belts in the back seat.
No wireless/cellphone use while driving.
Permit holders under 19 years cannot use any wireless/cellphone use while driving, including hands-free devices.
Exemption exists to contact a law enforcement agency, health care provider or emergency services agency in the case of an emergency.
Phase I: Instruction Permit Phase – Before You Can Move On
Before you can move on to phase II, you must:
Hold your permit for a minimum of nine months.
Before you can move on to the next step you must hold the instruction permit for at least nine months.
Practice driving a minimum of 50 hours, including 10 hours at night.

The 50 hours are in addition to any time spent behind-the-wheel with a driving instructor.
It is a good idea to keep a log of your driving practice, even if you don’t have to show this log when applying for your provisional license. A parent or legal guardian must, however, certify that you have completed a minimum of 50 hours of practice driving.
Not have any driving infractions, underage alcohol convictions or court supervisions during the previous nine-month permit phase.
To obtain court supervision for a traffic violation, a driver must appear in court with a parent/legal guardian and must attend traffic safety school. Limit one court supervision for serious driving offenses.
If you are convicted of a moving violation, there is an additional nine-month waiting period before you can apply for a driver’s license.
If you are caught driving without a permit you must wait until you are at least 18 years before you can apply for a license.
A violation of the night curfew may result in a permit suspension.
Phase II: Initial Licensing Phase (Provisional License) 16 – 17 years
To be eligible for phase II in the GDL program, a driver under 18 years must have completed a state-approved driver education course. Applicants between 18 and 20 years may instead complete a six-hour Adult Driver Education course.
A parent or legal guardian must certify that you have completed a minimum of 50 hours of practice driving, including 10 hours at night.
You must have held your permit for at least nine months.
Phase II: Initial Licensing Phase – Restrictions
With a provisional license you may drive without a supervising driver, but the license still has some restrictions.
No driving at night.
You cannot drive Sunday-Thursday between 10 p.m. and 6 a.m., and Friday-Saturday between 11 p.m. and 6 a.m.
Exemptions in the law allow you to drive to and from employment or school-sanctioned activities during curfew hours. You may also drive if accompanied by a parent or legal guardian.
No more than one passenger under 20 years for the first 12 months.
For the first 12 months or until you turn 18, whichever occurs first, the number of passengers is limited to one person under 20 years. A sibling, stepsibling, child, or stepchild of the driver is not counted towards this limit.
After 12 months or when you turn 18, the number of passengers is limited to one in the front seat and the number of safety belts in the back seat.
No use of cellphones.
All cellphone/wireless use while driving, including a hands-free device, is prohibited if you are under 19 years and not in an emergency.
Phase II: Initial Licensing Phase – Sanctions
If you are guilty of a moving violation within the first year of licensing, the passenger limitation is extended six months.
Two moving violation convictions within a 24-month period will result in a minimum one-month license suspension.
If the Secretary of State suspends your license, you may be retested and must pay a $70 reinstatement fee.
If you violate the nighttime driving restriction, your driving privileges may also be suspended.
