Every road sign, explained.

Organized by category and color. Road signs follow a federal standard, so the set here is the same set your state's knowledge test draws from.

How road signs work

Road signs follow a federal standard (MUTCD), so the same shape and color mean the same thing in every state. Color tells you the category: red for prohibitions, yellow for warnings, orange for work zones, green for guides, blue for services, brown for recreation, yellow-green for school and pedestrian zones. Shape tells you the function: an octagon is always a stop, a triangle pointed down is always a yield, a diamond is always a warning. Once you read the system, every sign falls into place.

Know These Cold

The signs that show up on knowledge tests most often. If you learn nothing else here, learn these 76.
