It’s two-for-one driving hacks day! First, you pull into the gas station to blow $50 on a tank. Which side should the pump be on again? Short of stopping the car and getting out to check, take a look at the gas gauge. Lots of cars have a handy little arrow pointing the way right on ’em (pictured).

Second, interstate numbers tell you which way the road runs. Even-numbered interstates run from east to west and odd-numbered go north to south, and triple-digit interstates loop or branch off from primary roads. Thanks, T!
