Guides for riders: emergency ID, helmets and numbers

Straight answers to the questions riders ask before they put a tag on a helmet. Every outside claim links to the source it came from.

• Do paramedics scan QR codes on helmets? An honest answer — Nobody is required to scan a helmet sticker. Who does, what they see, and what works when nobody does.
• Removing a motorcycle helmet after a crash: when it stays on, when it comes off — What the authorities say about taking a rider's helmet off, where to read it, and what your tag tells the first person there.
• Emergency numbers by country — and how your tag picks one — The number your tag's call button dials in each country, the official source for each, and how it decides.
• QR helmet sticker vs medical ID bracelet, dog tag or NFC chip — Four ways to carry your medical ID on a bike, what each does well, and why two beats one.
• The certification QR on a helmet vs your emergency tag: Brazil's Inmetro seal — Two QR codes on one helmet: one says the helmet is genuine, the other says who's wearing it. What each does, and how to place yours.
