Lawmakers in New York and California are set to establish legal limits for the use of so-called hoverboards, the battery-powered wheeled gadgets many kids got as gifts this holiday season. The devices don't fit under existing laws governing things like electric bikes or skateboards, but classifying them as motor vehicles (as they currently are in New York) doesn't help either.

California has gotten ahead of the issue. A bill signed by Gov. Jerry Brown in October and due to take effect on Jan. 1 allows hoverboards to be ridden at up to 15 mph in bike lanes on smaller streets — as long as the rider is 16 or over. Younger hoverboarders will have to stay on the driveway. Sidewalk use will be up to cities and counties to regulate on their own.
