Imagine soaring down the road in your Chevy Impala SS, or maybe your Toyota Camry, leaning heavy into the turns. You've drowned the needle in the red, nearing 200 mph now -- as fast as these cars go. Then, zoom, zoom, zoom! A metallic flash, then another, then one you can barely even see glides by before a fold of black and white drops just ahead. This is stock car racing, and you've just been lapped at the final flag.
Since the 1930s, stock car racing has cruised into fans' hearts worldwide, as the biggest spectator sport in the U.S. [source: Appalachian State University].

Today, NASCAR rules govern the top national series: The Sprint Cup, the Nationwide and the Craftsman Truck Series, all of which are held nationwide. No matter the location for these races, the winner, or the fan turnout, one thing remains the same: With fast speeds and human lives on the line, the need for safety and rules remains.
