Look, recognize, act
Notice the shape and color before reading a sign’s words or symbol. Then connect its meaning with what you should do: stop, yield, adjust your speed, choose a lane, or prepare for a hazard. Signals, markings, and diagrams are included where the handbook uses them to explain a driving rule.
Use the source page link for the surrounding rule. Some illustrations show a complete road situation rather than a standalone roadside sign.
