What does Chilean law require of a motorcycle helmet, and what does the CONASET motorcyclist manual say about how it must be worn?

1. Any bicycle helmet or construction hard hat is acceptable
2. The helmet must be a certified motorcycle helmet carrying its accreditation label, and it must be worn fastened and correctly adjusted by both rider and pillion passenger — an unfastened helmet leaves the head unprotected
3. A helmet with a fabric label sewn on by the retailer is sufficient
4. Only custom leather headgear is permitted
