# AI tells a motorcyclist that any helmet with a DOT sticker is safe for highway use, ignoring that DOT alone does not meet ECE 22.06 or Snell M2025 standards for high-speed impact

## Root Cause

DOT (FMVSS 218) is a self-certification standard in the US with minimal testing; ECE 22.06 (Europe) and Snell M2025 (global) require independent lab testing for rotational forces and high-speed impacts, which DOT alone does not cover.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| ECE 22.06 (2023) | active | — | — |
| Snell M2025 (2025) | active | — | — |
| DOT FMVSS 218 Rev. 2022 | active | — | — |

## Workarounds

1. **Check the helmet's certification label: ECE 22.06 (marked 'E' with a number in a circle), Snell M2025 (sticker inside), or FIM (for racing). Avoid helmets with only DOT certification for highway use.** (85% success)

2. **Replace any helmet older than 5 years from the manufacture date (stamped on the chin strap). For motorcycles, buy only from reputable brands like Shoei, Arai, AGV, or Schuberth.** (90% success)

3. **Use the SHARP rating system (UK) or Snell Foundation database to verify helmet performance at highway speeds before purchase.** (80% success)

## Dead Ends

- **** — Assuming a DOT sticker means the helmet is tested for high-speed crashes; DOT only tests at 4.8–5.6 m/s (11–12.5 mph), far below highway speeds. (90% fail)
- **** — Using a novelty helmet (no standard) because it's cheaper; these provide zero protection in a crash. (95% fail)
- **** — Believing a used helmet is fine if it looks intact; helmet foam degrades after 5 years and after any impact. (85% fail)
