Snow tire law?

I thought there are laws that require you to install snow tires on your car during winter season. This afternoon, there was snowstorm in NYC area and I have seen cars getting stuck or getting into accidents. The Chevy Express 15-passenger van that I was riding in couldn't go up hills. On TV news show, there were shots of city buses and trucks getting stuck and getting into accidents.

Only certain places require snow tires. I'd venture a guess it is only a requirement in 5% of all the US, if that.

There were several accidents in my area too. I don't have snow tires and I got around just fine. ;)

I think the only place in North America that requires winter tires is the province of Quebec.
