Sharing the road
Who is required to wear a helmet when riding a bicycle in California?
- Anyone under 18 years old. Correct answer
- Anyone under 21 years old.
- Anyone under 16 years old.
Why
The helmet line in the handbook's list of things a bicyclist must do carries one condition, and it is under 18. The other two ages are real ages in the handbook, just attached to other rules, which is what makes them easy to reach for. Twenty-one is the alcohol line, where the illegal blood alcohol concentration steps from 0.01% up to 0.08%. Sixteen is the age below which you can be ticketed for a passenger who is not wearing a seat belt. The rest of the bicyclist list reads like a driver's list, because bicyclists have the same rights and responsibilities as other drivers: obey signs and signals, ride in the same direction as traffic, yield to pedestrians, signal turns, and have fully functional brakes.
