Former heavyweight champion Mike Tyson took a hard fall while trying out his hoverboard on Christmas day.
Hoverboard are this season's hottest Christmas gifts. There are numerous reports of increased emergency room visits for broken limbs caused by falling off the electronic skate boards.
The many reports of hoverboard injuries prompted California Gov. Jerry Brown to sign a new hoverboard law that goes into effect on Jan. 1.
The new law requires hoverboard riders to wear a helmet be over age 16. The law will also limit hoverboards to roads with speed limits that are 35 mph or less.
