The right helmet

You must wear a certified bike helmet, not one designed for skateboarding or other sports.

Check your helmet for damage

Helmets are designed to absorb just one impact. If your helmet has been dropped or in a crash, it may not protect you. It doesn’t matter if the outer plastic shell is scratched, but if the inside polystyrene is cracked, replace it.

Ideally you’d buy a new helmet every 5 years.

How to check your helmet

  1. Hold the helmet so the inside faces up.
  2. Check there’s a ‘certified bike helmet’ sticker inside. That means the helmet’s safe for cycling.
  3. Work your hands around the rim of the helmet, gently trying to pull it apart. If you see any cracks in the polystyrene, the helmet needs to be replaced.

Fit your helmet correctly

Take a minute to make sure your helmet fits right every time you head out for a ride.
