Signs & Signals
1. You approach an intersection with a single solid white line across the road. Where must you stop?
- Behind the white line
- On the white line
- Just past the white line
Correct answer: Behind the white line
Why: The handbook specifically states that a single solid white line across a road at an intersection means you must stop behind the line for a traffic signal or sign.
Right-of-Way Rules
2. When entering a highway using an acceleration lane, what must you do before merging into traffic?
- Yield to traffic already traveling on the main road
- Signal and merge immediately at any safe gap
- Match the speed of highway traffic before yielding
Correct answer: Yield to traffic already traveling on the main road
Why: The handbook clearly states that a motorist must yield to traffic already traveling on the main road before moving into the proper lane. This is a fundamental safety rule for highway entry.
Alcohol & Drugs
3. What happens to your vision when you drink alcohol before riding a motorcycle?
- Seeing clearly and judging distance becomes difficult
- Your peripheral vision improves but central vision gets worse
- Your night vision gets better but daytime vision stays the same
Correct answer: Seeing clearly and judging distance becomes difficult
Why: The handbook clearly states that alcohol affects vision, making it difficult to see clearly and judge distance, which are critical skills for safe motorcycle operation.
Speed & Following Distance
4. At 20 mph, your vehicle should be able to stop within what distance?
- 25 feet
- 20 feet
- 30 feet
Correct answer: 25 feet
Why: The handbook states that a motorist should be able to stop within 25 feet at 20 mph. This is a specific safety standard for brake performance.
Parking Rules
5. When entering an angle parking space to your right, what should you do with your wheels after steering sharply into the space?
- Straighten the wheels to center the vehicle in the parking space
- Keep the wheels turned in the same direction until you shift to park
- Turn the wheels the opposite direction to compensate for the sharp turn
Correct answer: Straighten the wheels to center the vehicle in the parking space
Why: After steering sharply into an angle parking space, you must straighten the wheels to center the vehicle properly in the space. This ensures you're not taking up multiple spaces or parked crooked.
