- 1. Road Signs, Signals & Markings
What does a red, eight-sided (octagon) sign always mean?
- a.Slow down and be ready to yield
- b.Come to a complete stop
- c.No entry for any vehicle
- d.Railroad crossing ahead
Answer: b
Explanation: The octagon shape and red color are reserved exclusively for the STOP sign. You must make a complete stop at the marked stop line, crosswalk, or corner, then proceed only when it is safe. The unique shape lets you recognize it even when snow, dirt, or darkness hides the word STOP.
- 2. Road Signs, Signals & Markings
What does a solid yellow line next to your lane tell you?
- a.Passing across it is not permitted
- b.You may pass whenever it is clear
- c.The road ahead becomes one-way
- d.You must exit at the next ramp
Answer: a
Explanation: Yellow lines separate traffic moving in opposite directions. A solid yellow line on your side means passing is prohibited because oncoming traffic could be approaching. A broken yellow line means passing is allowed when the way ahead is clear; white lines, by contrast, separate lanes of traffic moving in the same direction.
- 3. Traffic Laws & Right-of-Way
At a four-way stop where two vehicles arrive at exactly the same time, who has the right of way?
- a.The larger or heavier vehicle
- b.The vehicle on the right
- c.The vehicle turning left
- d.Whoever accelerates first
Answer: b
Explanation: At a four-way stop, the vehicle that arrives first goes first. When two vehicles arrive at the same time, the driver on the left yields to the driver on the right. Always make eye contact and be prepared to yield even when you have the right of way, because right of way is something you give, not take.
- 4. Traffic Laws & Right-of-Way
When you want to make a legal left turn at an intersection, from which lane and to which lane should you turn?
- a.From the far left lane into the nearest left lane going your direction
- b.From any lane into any open lane
- c.From the right lane cutting across to the left
- d.From the center of the intersection into oncoming traffic
Answer: a
Explanation: Begin a left turn from the lane closest to the center line and finish in the lane just to the right of the center line on the road you enter. This keeps your path predictable and avoids crossing into other lanes of traffic. Yield to oncoming traffic and to pedestrians in the crosswalk before completing the turn.
- 5. Safe & Defensive Driving
The 'three-second rule' is used to help you judge what?
- a.How long to signal before a turn
- b.A safe following distance behind the car ahead
- c.How long you may park at a meter
- d.The time a yellow light stays lit
Answer: b
Explanation: The three-second rule sets a safe following distance. Pick a fixed object the car ahead passes, then count 'one-thousand-one, one-thousand-two, one-thousand-three'; if you reach the object before you finish counting, you are following too closely. Increase the gap to four seconds or more in rain, fog, or when following large vehicles.
- 6. Safe & Defensive Driving
When driving at night, why should you avoid overdriving your headlights?
- a.It wastes battery power
- b.It is illegal in every state
- c.Headlights damage your eyes at high speed
- d.You may not be able to stop within the distance you can see
Answer: d
Explanation: Overdriving your headlights means going so fast that your stopping distance is longer than the distance your headlights illuminate. If a hazard appears at the edge of your light, you could hit it before you can stop. At night, reduce speed so you can always stop within the area lit ahead of you, and use high beams on open roads when no traffic is near.
- 7. Sharing the Road
The large areas around a truck where the driver cannot see other vehicles are called what?
- a.No-zones (blind spots)
- b.Safety cushions
- c.Buffer lanes
- d.Escape ramps
Answer: a
Explanation: Large trucks have big blind spots on all four sides known as no-zones, including directly behind, in front, and along both sides. If you cannot see the truck driver in their side mirror, they cannot see you. Avoid lingering in these areas, and pass on the left where the blind spot is smaller.
- 8. Sharing the Road
You hear a siren and see an emergency vehicle approaching with flashing lights. What should you do?
- a.Stop immediately in your lane
- b.Speed up to get out of the area
- c.Continue at the same speed
- d.Pull over to the right edge and stop until it passes
Answer: d
Explanation: When an emergency vehicle approaches using its siren or flashing lights, pull over to the right edge of the road and stop until it has passed. This clears a path so police, fire, or ambulance crews can respond quickly. Do not stop in the middle of an intersection; drive through it first, then pull to the right.
- 9. Alcohol, Drugs & Impaired Driving
Under 'zero tolerance' laws, what BAC level can put a driver under 21 in violation?
- a.A very low level such as 0.01% or 0.02%
- b.Only 0.08% or higher
- c.0.05% exactly
- d.There is no limit for young drivers
Answer: a
Explanation: Because drivers under 21 cannot legally drink, zero-tolerance laws set a very low BAC threshold, commonly 0.01% or 0.02% depending on the state. Even a small amount of alcohol can trigger a license suspension for a minor. The safest and only legal choice for anyone under 21 is to drive with a BAC of zero.
- 10. Licensing & Penalties
What is the main purpose of a graduated (provisional) driver licensing system for new drivers?
- a.To make licensing more expensive
- b.To limit how far new drivers can travel
- c.To require new cars for teens
- d.To phase in driving privileges as experience grows
Answer: d
Explanation: Graduated licensing eases new drivers into full privileges in stages, starting with a supervised learner permit and moving to a provisional license with restrictions. Common restrictions limit nighttime driving and the number of young passengers during the first months. These rules reduce crash risk while new drivers build experience under lower-risk conditions.
