As far as I know all the LSR venues will require DOT and Snell 2005 or 2010.
Fred,
i just retired my 2005 bc one track (Loring? Maxton? Mojave?) said i needed a new helmet in 2012.
Texas rulebook says either 2005 or 2010.

PS:
I just checked the Loring rulebook:
"Snell rating label change from 2005 to 2010 will occur in 2016."
hmmm... looks like i was misslead and prematurely bought a new helmet.
wasted $500.
i'll give myself a pass since this is the 1st time i have wasted $500,
