Whether or not this is enforced is another thing. I've been warned in the past for not having a visor at all so now just leave it on the helmet.
My car is log booked with a hard top and is considered a closed car. I am not sure if this is standard policy for CAMS though and probably depends on how the scutineer feels on the day.

but still, a great entry price for someone who doesnt want to use the freebie helmets for karting...
And the construction of the shell and lining and the materials used and the size and shape of the opening. Lots of differences. I would say the major differences are the style of impact they are each designed for...a car helmet is designed to take multiple impacts on the same point.

I'm asking from an entry level's perspective for potential newbie track days
$50-$5000....no joke.
Personally I think that everyone has to take some responsibility for their own safety and make a choice they are comfortable with. This involves doing a bit of a risk assesment against the chosen level of motorsport and the kind of car you are driving.
If you are just in to 'round the cones' events on a flat open space....$50 open face helmet.
Bracket drag racing in a car that wheezes down the strip in 20 seconds without so much as a chirp from the tyres....$50 open face helmet.
Take a step up to full size circuits or hill climbs and suddenly speeds are higher and there is more risk of hitting something solid so you need to look at stepping up the quality of your safety kit. I spent $400 on a closed face helmet at Revolution Racegear, essentially it is a bike helmet but it fits nicely and is not to heavy. I was doing sprints and trackdays and I felt this helmet offered the level of protection appropriate for the style of event.
I have now stepped up in to a full race car and will be going wheel to wheel next season so I am looking at upgrading to a car specific helmet with a nomex lining and HANS posts. This is a step up with the level of risk to me.
Whatever your budget you MUST have a helmet that fits correctly. In an accident a $100 helmet fitted correctly is better for you than a $5000 helmet that does not fit.
You also need to be comfortable, if you have a modified car on semi-clicks and with good suspension you would be surprised at how heavy your helmet gets mid corner!! Some helmets will pinch your head in the wrong place and other helmets will slop around and others will have a chin strap you cant do up on your own or digs in to you.
When you try it on what does the helmet do when you shake and nod your head?
Can you grab the front or back of the helmet and rotate it forwards or backwards? If the helmet is not fitting you properly you will be able to halfway pull it off doing this.
Do you wear glasses? If not make sure you take your sun glasses shopping with you and see how they feel when your helmet is on. I wear glasses and with a helmet on I can not get the arms to sit on my ears, I now chose frames with straight arms so they do not dig in to the side of my head.
