1. What is the maximum motor output allowed for a legally classified e-bike in California?

• 250 watts
• ✓ 750 watts
• 1,000 watts

California caps e-bike motors at 750 watts across all three classes; anything above that is not treated as a bicycle under state law.

2. Which e-bike class can be propelled entirely by a throttle, without the rider pedaling?

• Class 1
• ✓ Class 2
• Class 3

Class 2 e-bikes allow throttle-only propulsion, unlike Class 1 and Class 3, which only assist while the rider is pedaling.

3. At what speed does motor assistance cut off on a Class 1 e-bike?

• 15 mph
• ✓ 20 mph
• 28 mph

Class 1 e-bikes provide pedal-assist power only up to 20 mph, after which the motor stops helping.

4. What is the minimum age to legally operate a Class 3 e-bike in California?

• 14
• ✓ 16
• 18

Class 3 e-bikes, which assist up to 28 mph, require the rider to be at least 16 years old.

5. Which statement about Class 3 e-bike helmet requirements is accurate?

• Only riders under 18 need one
• ✓ All Class 3 riders must wear a helmet regardless of age
• Helmets are optional for Class 3 riders

Unlike Class 1 and Class 2, every operator of a Class 3 e-bike must wear a helmet no matter their age.

6. California law generally requires a slower-moving cyclist on a roadway to ride:

• As far left as possible
• ✓ As close as practicable to the right-hand edge
• In the center of the traffic lane

Cyclists moving slower than traffic must stay close to the right edge, though this means as far right as reasonable and safe, not literally the edge.

7. Which of these is a recognized legal reason for a cyclist to move away from the right edge of the road?

• ✓ Preparing to turn left at an upcoming intersection
• Riding faster than the posted speed limit
• Wanting to reach a destination sooner

Cyclists may leave the right edge to set up for a left turn, along with passing and avoiding hazards.

8. A "substandard width lane," which lets a cyclist ride away from the right edge, is defined as a lane that:

• Has no painted bike lane markings at all
• ✓ Is too narrow for a car and a bicycle to safely travel side by side
• Has visible speed bumps

If a lane can't fit a car and a bike safely next to each other, the cyclist is allowed to take a more central position.

9. On a one-way street with two or more marked traffic lanes, where may a cyclist legally position themselves?

• Only in the rightmost lane
• ✓ As near the left-hand edge as practicable
• Only in a marked bike lane

California law makes an exception for one-way roads with multiple lanes, allowing cyclists to ride near the left edge if practicable.

10. What does California's Daylighting Law (AB 413) primarily restrict?

• Bicycle helmet colors
• ✓ Parking near crosswalks and intersections
• Nighttime bike riding hours

The Daylighting Law limits how close vehicles can park to crosswalks so drivers and pedestrians can see each other clearly.

11. Under the Daylighting Law, how close to a crosswalk is parking generally prohibited?

• 10 feet
• ✓ 20 feet
• 30 feet

Vehicles generally may not park within 20 feet of the approach side of a marked or unmarked crosswalk.

12. When a curb extension (bulb-out) is present near a crosswalk, the Daylighting Law's minimum no-parking distance drops to:

• 10 feet
• ✓ 15 feet
• 20 feet

Where a curb extension narrows the roadway, the required clearance is reduced to 15 feet instead of the standard 20.

13. How much space must a driver leave when passing a bicyclist traveling in the same direction?

• 1 foot
• ✓ 3 feet
• 6 feet

The Three Feet for Safety Act requires drivers to leave at least three feet of space between their vehicle and a cyclist when passing.

14. If road conditions make it impossible for a driver to leave three feet while passing a cyclist, what must the driver do?

• Pass anyway at normal speed
• ✓ Slow down and pass only when it can be done safely
• Honk and pass immediately

When three feet isn't possible, the driver must reduce speed and wait for a safe opportunity that won't endanger the cyclist.

15. Drivers must yield to pedestrians crossing within:

• Only marked crosswalks
• ✓ Marked crosswalks and unmarked crosswalks at intersections
• Any location a pedestrian chooses to cross

California law extends right-of-way protection to unmarked crosswalks at intersections, not just painted ones.

16. What must a pedestrian avoid doing, even while using a crosswalk?

• Wearing dark clothing
• ✓ Suddenly stepping off the curb into the path of a vehicle so close it poses an immediate hazard
• Crossing during daylight hours

Pedestrians still owe a duty of care and can't step into traffic that's already too close to stop safely.

17. When a pedestrian crosses outside any marked or unmarked crosswalk, who generally has the right-of-way?

• The pedestrian, always
• ✓ Vehicles close enough to pose an immediate hazard
• Whoever arrives at the spot first

Outside of crosswalks, the right-of-way rule flips, and the pedestrian must yield to nearby vehicles.

18. California's bicycle helmet law applies to riders under what age?

• 16
• ✓ 18
• 21

Anyone riding a bicycle or e-bike in California under age 18 is legally required to wear a helmet.

19. Which of these bicyclists is legally required to wear a helmet in California, regardless of age?

• A Class 1 e-bike rider on a bike path
• ✓ A Class 3 e-bike rider
• A pedestrian walking a bicycle

Class 3 e-bikes are the one category where the helmet mandate applies to every rider, not just minors.

20. For night riding, California law requires a bicycle to have a front lamp visible from at least how far away?

• 100 feet
• ✓ 300 feet
• 500 feet

A bicycle's front lamp must be visible from 300 feet so drivers and pedestrians can spot it in the dark.
