1. Children under 2 years of age should generally be:
In a child booster seat
In the front seat with a lap belt
✓ In a rear-facing car seat in the back seat
Facing any direction—at the driver's discretion
Why: Children under 2 years of age must ride in a rear-facing car seat, unless they already weigh 40+ pounds or are taller than 40 inches.
2. According to Michigan's child passenger safety law, which children generally must be secured in a car seat or booster seat?
Only infants under 1 year old
✓ Children under age 8, unless they are 4'9" or taller, must use a car seat or booster appropriate for their size
All children under age 16
Car seats are recommended but never legally required
Why: Michigan law requires children under age 8 to ride in a car seat or booster seat suited to their size, unless the child has already reached 4 feet 9 inches in height.
3. Michigan's seat belt law requires which of the following?
Only the driver must wear a seat belt
Only front-seat passengers must wear a seat belt
✓ All occupants, front and rear, must wear a seat belt, and officers may stop and ticket a vehicle solely for a seat belt violation
Seat belts are optional for anyone over age 18
Why: Michigan requires all vehicle occupants, in both front and rear seats, to buckle up, and it is a primary enforcement law, meaning police can pull you over and cite you for that violation alone.
4. The recommended following distance from the vehicle ahead under good conditions is:
1 second
✓ 3 seconds
10 seconds
One car length, regardless of speed
Why: The 3-second rule scales with speed, unlike a fixed distance in "car lengths," and allows time to react.
5. Drivers 18 years of age or older may hold a phone in their hand while driving only to:
Talk freely while holding the phone in your hand
✓ With a single tap or swipe, turn on speakerphone or navigation when the phone is mounted in the holder
Texting at a traffic light
Using the Internet while stuck in traffic
Why: The phone must be secured in the holder; you may tap it once to activate speakerphone, but you may not hold or use it in your hand.
6. How does Michigan law treat cell phone and wireless device use by drivers under 18?
It is treated exactly the same as for adult drivers
✓ Under-18 drivers are prohibited from using a cell phone or wireless device at all while driving, including hands-free, not just handheld use
There is no restriction at all for drivers under 18
It only applies while driving on the freeway
Why: While Michigan generally restricts handheld phone use for all drivers, drivers under 18 face a stricter rule barring essentially all cell phone and wireless communication device use, including hands-free, while behind the wheel.
7. When are you generally required to turn on your headlights while driving?
Only when it is completely dark outside
✓ From 30 minutes after sunset to 30 minutes before sunrise, and anytime windshield wipers are in use due to rain
Only on freeways
Headlights are never legally required if streetlights are on
Why: Drivers are generally required to use headlights from half an hour after sunset until half an hour before sunrise, as well as any time weather conditions require using the windshield wipers.
8. At a railroad crossing with flashing signals, you must stop no closer than:
5 feet from the nearest rail
✓ 15 feet from the nearest rail
50 feet from the nearest rail
All you have to do is slow down
Why: Stop at least 15 feet away from the nearest rail and wait until the signals stop flashing and the crossing is safe.
9. When is making a U-turn generally prohibited?
U-turns are always legal everywhere
✓ In business districts and anywhere a sign specifically prohibits it, or when it cannot be made safely
Only on Sundays
Only if there are no other cars nearby
Why: U-turns are generally restricted in business districts and wherever a posted sign prohibits them, and they must never be made unless it can be done safely and without obstructing traffic.
10. How many penalty points does a typical traffic violation—such as speeding—add to a driver's record?
0 points
✓ 1 point
3 points
5 points
Why: Most violations are worth 1 point; more serious ones (reckless driving, DUI, fleeing the scene of an accident) are worth 2 points.
11. After accumulating how many points over a 12-month period can a driver be deemed a “negligent driver” and have their license suspended?
2 points
✓ 4 points
8 points
12 points
Why: The thresholds are as follows: 4 points for 12 months, 6 points for 24 months, or 8 points for 36 months.
12. When another driver honks to signal that they want to pass you, you should:
Speed up so you don't miss it
✓ Maintain your speed (or slow down slightly) and stay in your lane
Pull over to the side of the road
Flash your high beams at him
Why: Allow the driver who is passing you to complete the maneuver safely—do not accelerate or get in their way.
13. What does Michigan's Move Over law require when approaching a stopped emergency, service, or maintenance vehicle with flashing lights?
Ignore it and maintain your speed
✓ Move over a lane if possible, or slow down significantly if you cannot change lanes safely
Stop your vehicle completely on the freeway
Flash your headlights and honk
Why: Michigan's Move Over law requires drivers to move into a non-adjacent lane when safely possible, or to slow down considerably, when passing a stopped vehicle with flashing lights, such as police, emergency, tow, or maintenance vehicles.
14. A red curb means:
Short-term parking is permitted
✓ Stopping, standing, and parking are prohibited at all times
This is the loading zone for trucks
Parking for people with disabilities only
Why: Red always indicates a complete ban on stopping, standing, and parking—with no exceptions.
15. A blue curb is intended for:
Commercial loading
✓ Vehicles with a valid disability placard or license plate
For taxis only
For buses only
Why: Blue curbs are for vehicles with a disability placard or license plates; parking there without one is a serious violation.
16. When parking uphill on a street with a curb, you should turn the front wheels:
✓ Away from the curb
Toward the curb
Straight
It doesn't matter
Why: Turn the wheels away from the curb so that if the car rolls backward, it will come to rest against the curb.
17. When parking downhill, you should turn the front wheels:
Away from the curb
✓ Toward the curb
Straight
It doesn't matter
Why: Turn the wheels toward the curb so that the car, as it rolls backward, comes to a stop against the curb rather than rolling out onto the roadway.
18. A school bus ahead has stopped with its red lights flashing and stop-arm extended, on a two-lane road with no physical median. You should:
Pass carefully at reduced speed
✓ Stop, regardless of which direction you're traveling, until the lights stop flashing
Stop only if you're behind the bus, not if you're approaching it
Proceed if no children are visible
Why: On undivided roads, traffic in both directions must stop for a school bus with flashing red lights and an extended stop arm, and may only proceed once the lights stop flashing.
19. An emergency vehicle with sirens and flashing lights is approaching from behind. You should:
Speed up to clear the intersection first
✓ Pull over to the right edge of the road and stop until it passes
Stop immediately, wherever you are, even mid-intersection
Ignore it unless it's directly behind you
Why: Move as far right as safely possible and come to a stop (unless a police officer directs otherwise), clearing the way for the emergency vehicle.
