What color and shape are most warning signs (such as 'curve ahead' or 'merging traffic')?

Correct answer

Yellow diamond

  1. A Red octagon
  2. B Yellow diamond
  3. C Green rectangle
  4. D Blue circle

Why this is the answer

Most WARNING signs are YELLOW DIAMONDS (diamond-shaped with a yellow background and black symbols/letters). DMV/permit test. Warning signs alert drivers to hazards or changing conditions AHEAD — curves, intersections, merging traffic, pedestrian crossings, slippery roads, animal crossings, etc. — so drivers can prepare. SIGN COLORS: YELLOW = general warning; ORANGE = construction/work zone warning; RED = stop/yield/prohibition; GREEN = guide/directions; BLUE = services (gas, food, lodging); BROWN = recreation/parks; WHITE = regulatory (speed limits, rules). Knowing warning signs are yellow diamonds is a fundamental, commonly tested sign concept.
