Minnesota CDL Road Signs by Shape & Color Test 2026

Reading a sign at a glance is essential when you are piloting a heavy truck, and the Minnesota CDL road signs test starts with shapes and colors. This practice test teaches you to identify a sign by its outline and hue before you even read the words, a skill that buys precious seconds on the highway.

The 2026 questions cover the octagon for stop, the triangle for yield, the diamond for warnings, the rectangle for regulatory and guide messages, and the pennant for no passing. Colors carry meaning too: red for prohibition, yellow for caution, orange for work zones, green for guidance, and blue for services. This overview follows the Minnesota Commercial Driver's License Manual.

Sign recognition supports safe commercial driving throughout Minnesota and appears in your CDL knowledge preparation. The complete manual text is posted on our separate handbook page.
