Jr Kart helmets

[RTR86]

After lots of time on Google, all I've found is that I should ask my club about what helmet requirements are for karts. Are Snell M or K allowed?

4.3.1 Helmets
Helmets meeting the following standards must be worn while on course:
All helmets meeting the latest or two immediately preceding Snell Foundation
standards (SA2015, SA2010, SAH2010, SA2005, SA2000, M2015, M2010,
M2005, M2000, K2015, K2010, K2005, K98); SFI standards 31.1, 41.1, 31.1A,
31.2A, 41.1A, 41.2A; ECE R22.05; FIA standards 8859-2015, 8860-2010, 8860-
2004; or British spec BS6658-85 type A are acceptable.
Full face or modular helmets shall be worn while competing in an open-wheel
car, formula car, or kart. Face shield, goggles, or similar face protection (conventional
eyeglasses are not sufficient) shall be worn while competing in any
other vehicle with less than the standard-size windshield.

Formula Junior drivers must use helmets meeting the above, SFI 24.1 (Youth
Helmets), Snell CMR2007 (Children’s Motorsports Restricted), or Snell
CMS2007 (Children’s Motorsports Standard) specifications. Also, Formula
Junior helmets must be of closed face design incorporating full face shields
and chin bars.

For maximum protection, helmets must fit securely and should provide adequate
peripheral vision. The chin strap must be securely fastened. Loaner
helmets should be available to vehicle occupants not having their own.
