Riding a bike or a scooter safely, sentence 0

A helmet protects your brain if you fall; it only works if it fits: level on your head, low on your forehead (about two fingers above your eyebrows), straps forming a V under each ear and the chin strap snug, so it does not slide when you shake your head.

Who acts: helmet, you, straps · What happens: protect, fall, work, fit, form, not slide · To what, where: brain, level, head, V, ear
