WATCH: Class-action requests multiply over Highway 13 mess

Two separate law firms have filed documents asking the courts to authorize a class-action lawsuit on behalf of those who spent hours stuck on Highway 13 during last Tuesday's epic snowstorm.

Last Thursday, the first collective action was filed on behalf of those stuck on the highway, unable to move, while snow quickly accumulated around their cars.

At that time, lawyers were seeking $2,000 for each victim. On Monday, $500 was added to that amount, for additional punitive damages.

As many as 1,000 people could wind up filing claims.
