Ch. 3 · Bikes & E-Mobility

A bicycle's brakes are acceptable if they can stop the bicycle within 5 meters after applying the brakes at a speed of 10 km/h.

[True / False · Medium]

Answer: ✕ False

Explanation

The Rules of the Road, Chapter 3, Section 2, 2(6) states: "Both front and rear brakes must work well (can the bicycle stop within 3 meters after applying the brakes at a speed of 10 km/h?)." The correct distance is within 3 meters, not 5 meters.

Yep! Think of it this way—good brakes = shorter stopping distance = safer for everyone around you!
