It’s not uncommon for people in rural parts of the U.S. to learn to drive when they’re young, sometimes even before they reach their teens. But the news that a 13-year-old was behind the wheel of a pickup truck that blew a tire and struck a van in West Texas and killed nine people put a renewed focus on the practice. National Transportation Safety Board Vice Chairman Bruce Landsberg said at a news conference Thursday that the dangers of underage driving put it on the agency’s “most-wanted list.” William Van Tassel of AAA noted the driver's age was just one risk factor. The crash happened at night and on a road with a high speed limit when a spare tire blew.
