I think the wal mart ones are only DOT. At the only auto-x I've been to, they didn't check helmets, other than to just see that you had one on. Do most clubs tend to check?
Also, are open face helmets allowed as long as they are rated m95 or better? Is m2000 allowed? Sorry for all the questions. I just want to find the cheapest helmet I can, since it will most likely only be used once a month or less.
