Missouri Road Sign Practice Test

How road signs are tested in Missouri

The Missouri Driver Guide describes a separate road sign test as part of the Missouri driver exam. It doesn't give that test's pass mark, so the 20-sign test here shows your score without a pass or fail.

Signs from the Missouri Driver Guide (Revised August 2026). What every kind of sign means, by shape and color: our road sign guide.

Signs the Missouri Driver Guide adds

• Traffic Control

  The Stop Ahead sign warns of a stop sign ahead; be prepared to stop. p. 46

• Road Intersections

  A speed plate under the Roundabout Ahead sign shows how slow to go into the roundabout; slow down to that speed as you approach. p. 48

• Tips For Avoiding a Deer-Vehicle Crash

  Be especially alert and careful in areas marked with deer crossing signs. p. 59

• Other Equipment Required by Law

  Vehicles moving 25 mph or slower need a clean, reflective slow-moving vehicle sign at the rear center, four feet or more above the road, from sunset to half an hour before sunrise. p. 85

• Intersections

  At a four-way stop, the driver who reaches the intersection first goes first, after coming to a complete stop. p. 23

• Traffic Signals

  In Missouri, after a complete stop you may turn right on red when the way is clear, unless a No Right Turn On Red sign is posted. p. 44

• Sign Colors

  White and black on a road sign mean it is regulatory: it states a rule you must obey. p. 45

  Missouri interstates have a 40 mph minimum speed under normal conditions; if that is too fast for you, use another route. p. 50

• Work Zone Signs

  Speeding or passing in a Missouri state-road work zone brings a minimum fine of $250 (first offense) or $300 (later offenses), on top of other fines. p. 51

• Railroad Crossing

  The crossbuck sign at a railroad crossing means the same as a yield sign: yield to trains. p. 51

  A pennant-shaped sign (a sideways triangle) marks a no-passing zone. p. 45
