Thought you were being smart by letting your car idle to warm up in the cold? Turns out, you could get slapped with a hefty fine (up to $500!) in many states thanks to “anti-puffing” laws. Not only is it illegal in a bunch of places, but leaving your car running and unattended is basically an open invite for thieves. Some states give you 5 minutes, others none at all—so check the rules before you get cozy! #Transportation #WinterDriving #CarTips
