The 9 most dangerous things drivers do

6. Drafting tractor trailers

Yes, following closely behind a tractor trailer can increase your fuel economy. That doesn’t mean you should do it. Drafting works for NASCAR drivers, so it makes sense that a 4,000-pound car can “hide” in the low pressure zone behind a 13-foot-tall, 80,000-pound big rig. Back in 2007, the MythBusters even proved that it worked. But they also pointed out that following closer than 150 feet behind a truck is really dangerous. Even that distance gives a driver less than two seconds to react if the trucker suddenly slams on the brakes. Other things to consider are that truck drivers can’t see what’s directly behind them, and the relationship between trailer heights and car hood heights is a recipe for decapitation.
