1. When riding a motorcycle, the best way to be seen by other drivers is to:

• Wear dark clothing
• Ride in the center of the lane at all times
• Wear bright clothing and use your headlight ✓
• Ride close to other vehicles

解析： Bright clothing and a headlight make you visible. Avoid riding in other drivers' blind spots.

2. A motorcycle's front brake provides approximately what percentage of stopping power?

• About 25%
• About 50%
• About 70% or more ✓
• About 10%

解析： The front brake supplies roughly 70% or more of a motorcycle's stopping power — use both brakes for maximum control.

3. The safest lane position for a motorcycle is one that:

• Keeps you in the center of the lane at all times
• Maximizes your visibility and escape options ✓
• Stays as far right as possible
• Follows directly in the tire tracks of the car ahead

解析： Choose a lane position that maximizes visibility to other drivers and gives you room to maneuver or escape hazards.

4. When turning a corner on a motorcycle, you should:

• Brake hard while leaning
• Slow down before the turn, then lean and accelerate smoothly ✓
• Accelerate before the turn and brake in the turn
• Keep a constant throttle through the turn

解析： Slow down before the turn, then lean into it and accelerate smoothly through. Braking mid-turn reduces stability.

5. Riding a motorcycle after drinking alcohol:

• Is fine in small amounts
• Increases your risk of a crash even below the legal limit ✓
• Only matters above the legal limit
• Is safer than driving a car after drinking

解析： Even small amounts of alcohol slow reaction time and reduce balance — both critical on two wheels. Never ride after drinking.
