    Going along with reading a map most people don’t know how roads and exits are numbered. It’s not a random jumble. This makes reading a map and just knowing what direction you’re traveling in general much easier. This is for the US.

    Interstates

    1 or 2 Digits: Main routes. North-South routes have odd numbers, increasing from west to east (e.g., I-5 to I-95). East-West routes have even numbers, increasing from south to north (e.g., I-10 to I-90).

    3 Digits (Even First Number): A loop or beltway that connects to the main interstate at both ends.

    3 Digits (Odd First Number): A spur route that connects to the main interstate at only one end.

    Exit numbers

    They mirror the mile markers which show up on maps. Numbers increase from south to north or west to east. So you could basically make a ‘cheat sheet’ of your exit numbers. Then while driving you know how far till your next exit.

    I’ve seen this not be true on occasion but it should be mostly true. If the exit sign is on the right of the road sign then the exit is to the right. If it’s on the left then it exits to the left.

    All knowledge that I feel got lost to time for the most part. They should teach it in drivers ed but I don’t think they do.
