Warning, Construction & Information SignsStandalone practice
This interstate route marker shows an odd route number. Which way does that interstate generally run?
Correct answer: North and south
Why
Route markers help you follow a trip plan: their shape tells you the type of road, and the number tells you its direction. The 2026 guide explains that for three-digit interstates, an even first digit means a loop around a city and an odd first digit means a spur into it. Checking the route number and direction on the sign helps you avoid wrong turns.
