The First Steps With Bike and Helmet Safety
Bike and Helmet Safety: the few things that matter most, and the mistakes that catch people out early.
On this page
Wearing a properly fitted helmet and following the rules of the road on bikes, scooters and skateboards.
Key takeaways
- Helmet standard: look for a label showing it meets the Consumer Product Safety Commission standard
- Fit: level on the head, about two finger widths above the eyebrows
- Most useful single change: Make helmet use a rule for every ride, for adults as well as children.
- Commonest mistake: Wearing a helmet tipped back on the forehead.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
Why bother
Head injuries are the most serious injuries in bike crashes, and a well-fitted helmet lowers the risk.
Start here
Start with two. Add the rest once those have stopped taking effort.
- Make helmet use a rule for every ride, for adults as well as children
- Ride in the same direction as traffic and obey traffic signals
Then add these
Once the first two are automatic, these are worth adding.
- Wear bright clothing during the day and reflective gear at night
- Check brakes and tires before riding

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarized or generalized beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
