I just saw that New Jersey events have officially expired Snell 2010 helmets. Make sure you now have the 2015 rating for any track/autocross event at NJMP or wherever in the state.
Fortunately I just picked up a Roux full face helmet with a 2015 rating, although I've yet to use it at an event.
I believe most other locations allow the 2010 for 1 more year.
