Every question in Practice Test 1, with the correct answer and an explanation for each.
-
Q1. When must you drive slower than the posted speed limit?
Correct answer: Anytime road, weather, or traffic conditions make the posted limit unsafe
Why: You must always adjust your speed to road, traffic, and weather conditions, even if this means driving below the posted limit.
-
Q2. When you see a STOP sign and a marked stop line, where do you make your complete stop?
Correct answer: At the stop line before entering the crosswalk or intersection
Why: Come to a full stop at the stop line first. If there is no line, stop before the crosswalk or where you can see clearly.
-
Q3. A solid yellow line on your side of the center line means you:
Correct answer: May not pass because it is unsafe to do so here
Why: A solid yellow line on your side marks a no-passing zone where sight distance or other conditions make passing dangerous.
-
Q4. A broken yellow center line between two lanes of traffic means:
Correct answer: Passing is allowed when it can be done safely
Why: Broken yellow lines between opposite-direction lanes show where you may pass if there is enough clear space ahead.
-
Q5. What does a solid white line between lanes usually mean?
Correct answer: Lane changes are discouraged and should be made only when necessary
Why: Solid white lines separate lanes going the same way and warn you not to weave in and out unless you really need to.
-
Q6. Before changing lanes on a highway, what is the correct order of actions?
Correct answer: Check mirrors, signal, check your blind spot, then move when clear
Why: Safe lane changes always use mirrors, turn signals, and a quick look over your shoulder into the blind spot.
-
Q7. The main purpose of the three-second rule is to help you:
Correct answer: Keep a safe following distance under normal conditions
Why: Counting at least three seconds between the car ahead and your car passing the same point helps you avoid rear-end crashes.
-
Q8. You should increase your following distance beyond three seconds when:
Correct answer: Roads are wet, visibility is poor, or you are following a large vehicle
Why: In rain, fog, heavy traffic, or when following trucks, you need extra space so you can react and stop safely.
-
Q9. On a multilane road, the left lane is usually used for:
Correct answer: Passing and for faster-moving traffic
Why: Stay in the right lane when you can and use the left lane mainly to pass or prepare for a left turn.
-
Q10. When another driver is following you too closely (tailgating), the safest thing to do is to:
Correct answer: Gradually slow down and, when possible, change lanes so they can pass
Why: Creating space and letting the tailgater get around you lowers the risk of a rear-end collision.
-
Q11. If your view at an intersection is blocked by buildings, trees, or parked cars, you should:
Correct answer: Move forward slowly until you can see clearly, then proceed if it is safe
Why: Creep forward carefully and look for cross traffic and pedestrians before you enter the intersection.
-
Q12. A green arrow pointing left at an intersection means you may:
Correct answer: Make a protected left turn; oncoming traffic should have a red light
Why: A steady green arrow gives you a protected turn in that direction while oncoming traffic is stopped.
-
Q13. When a steady yellow light appears as you approach an intersection, it means:
Correct answer: The light is about to turn red; stop if you can do so safely
Why: A steady yellow warns that the green phase is ending. Prepare to stop before the intersection if it is safe to do so.
-
Q14. A flashing red traffic light at an intersection means you must:
Correct answer: Come to a complete stop, then proceed when it is safe

-
Q18. If your vehicle begins to hydroplane on a wet road, you should:
Correct answer: Ease off the accelerator and steer straight until your tires grip again
Why: Sudden braking or steering can cause a skid. Gently reducing speed helps your tires regain contact with the road.
-
Q19. On a wet roadway compared to dry pavement, your stopping distance will be:
Correct answer: Longer, so you must slow down and leave more following distance
Why: Rain reduces traction and increases the distance needed to stop, so you should reduce speed and increase space.

Why: Drivers must either change lanes away from the vehicle or slow down significantly to protect workers and officers.
-
