my thoughts only, all snell rated or dot helmets meet or exceed these standards as the minimum. the safety factor in a helmet is all about the padding, graphics have no value whatsoever. snell rating was from one instituion that wanted higher than dot standards. i'd suggest zeebs buy one that is in your safety and price range with the best ratings you can find. as long as the fit is correct you should be okay for the dollar you spent. a helmet will never protect yer head from all impacts, and probably never will, you just want your best chance of survival. all helmet manufactures recommend replacing a helmet if it is dropped on concrete or been in an accident, as the linner crush properties will be compromised and you won't see it by eye all the time.
where a helmet, as any helmet will be better than none.
Careful with this statement (the one in bold), as the padding (in the sense that Zeebs is talking about it) has absolutely no bearing on safety, as it is just liner to make the helmet more comfortable, and fit better. The safety actually comes from a combination of the shell (plastic or carbon) and the foam inside the helmet. The shell if there to dissipate an impact point over the entire surface area of the helmet. If the impact force is greater it will move into the foam, which will further dissipate the impact, and if the impact is great enough there the foam with compress/crack. This is when the helmet is considered no good any more.
Yes, these standards are a minimum, and there is no way to tell by how much a helmet exceeds these standards. If the helmet passes the DOT standards by 1G or by 100G there is no way to tell. Imdoo'n nailed it when he said 'as long as the fit is correct', as the helmet should be snug and not loose on your head. For most snowmobile and quad purposes, DOT will certainly get you be, as you aren't dealing with the speeds that motorcyclists are dealing with.
