Missouri’s road sign test deserves more attention than most people give it before exam day. It is not just a few signs tossed into the background of the written test. Missouri separates the driver examination into four parts: the written knowledge test, the vision test, the road sign test, and the driving skills test. The Missouri State Highway Patrol handles the testing itself, while the Missouri Department of Revenue issues the actual permit or license afterward. So, yes, passing matters — but a passed test record still has to be taken to a Missouri license office before it becomes real driving privileges. This Missouri DMV road sign test gives you a focused way to review the sign-recognition portion without digging through every topic at once. The practice test includes 20 multiple-choice questions based on the official Missouri Driver Guide, with attention to the signs, signals, colors, shapes, and pavement markings drivers are expected to know. Red signs usually mean stop, yield, do not enter, or otherwise pay attention now. Yellow warns you about what is coming. Green points you toward routes, exits, directions, and distance. The shapes matter too — octagons, diamonds, triangles, rectangles — because they often tell you what kind of message you are dealing with before you have fully read the words. That kind of quick recognition matters on Missouri roads. Kansas City traffic, St. Louis interchanges, Ozark curves, small-town intersections, and long rural highways all put road signs in front of drivers in slightly different ways. The rules do not change, obviously, but the setting does. A sign that feels obvious in a study guide can feel a little less obvious when traffic is moving, someone is braking ahead of you, and you are trying to figure out whether your lane is about to disappear. Not dramatic, just true. It also helps to know where this road sign test fits into the larger Class F testing process. The separate 25-question written knowledge test covers Missouri traffic laws, safe driving, roadway rules, sharing the road, impaired driving, distracted driving, vehicle equipment, and other material from the Driver Guide. That test is multiple choice, not open book, and you need 20 correct answers to pass. Before you can take the driving skills test, Missouri expects you to pass the written, vision, and road sign portions first. Use this MO road signs practice test as a serious warm-up, not as a replacement for the Missouri Driver Guide or a formal drivers ed course. It is built to feel exam-style, with familiar topics and practical wording, so you can catch the weak spots here instead of finding them out at the testing station.

Sample Missouri Permit Test Questions

Question 1

A traffic signal changes from green to steady yellow as you approach. What should you do?

As you near an intersection, the traffic light changes from green to yellow. Your best action would be to:
  1. A Accelerate before the red light appears
  2. B Brake sharply regardless of your distance from the intersection
  3. C Enter the intersection and stop there
  4. D Stop before entering unless you are too close to stop safely

Correct answer: D – Stop before entering unless you are too close to stop safely

Missouri law states that a steady yellow signal warns that the green movement is ending and red will follow. The Driver Guide says to stop unless you are already within the intersection or are too close to stop safely before entering. The proper response depends on whether you can make a safe stop, not on trying to beat the red light.

Question 2

At a red light where both streets carry two-way traffic, which movement may be made after a full stop if no sign prohibits it?

  1. A Proceed straight when the intersection looks clear
  2. B Turn left when no vehicles are approaching
  3. C Turn right after yielding to pedestrians and other traffic
  4. D Make any of these movements

Correct answer: C – Turn right after yielding to pedestrians and other traffic

In Missouri, a driver facing a steady red signal must stop at the prescribed location. After stopping, the driver may cautiously turn right unless a posted sign prohibits the turn. The driver must yield to pedestrians and to other traffic proceeding as directed by the signal.

Question 3

A stop sign has a marked stop line before the crosswalk. Where must you stop?

  1. A Where you have the clearest view, even if it is beyond the line
  2. B After crossing the stop line or crosswalk
  3. C Before your vehicle reaches the stop line
  4. D At least five feet before the stop sign

Correct answer: C – Before your vehicle reaches the stop line

Stop at the clearly marked stop line when one is present. If there is no stop line, stop before entering the crosswalk on the near side. When neither exists, stop at the nearest point before the intersecting roadway from which you can see approaching traffic.

Question 4

A steady yellow arrow appears after the green arrow for your left-turn lane. What should you do?

  1. A Accelerate to complete the turn before the signal changes
  2. B Continue because the turn remains protected
  3. C Prepare to yield to oncoming traffic or stop for the next signal
  4. D Back out of the turn lane

Correct answer: C – Prepare to yield to oncoming traffic or stop for the next signal

The Missouri Driver Guide explains that a steady yellow arrow follows a green arrow as the protected phase ends. The next indication may be a circular green light, a flashing yellow arrow, or a red light. Be ready to yield to oncoming traffic or to stop, depending on the signal that follows.

Question 5

What is the usual top-to-bottom order of a vertical three-color traffic signal?

From top to bottom, the following is the proper order for traffic lights:
  1. A Red, yellow, green
  2. B Red, green, yellow
  3. C Green, red, yellow
  4. D Green, yellow, red

Correct answer: A – Red, yellow, green

On a standard vertical traffic signal, red is at the top, yellow is in the middle, and green is at the bottom. This standardized arrangement helps drivers recognize each indication by both color and position.

Question 6

If a traffic officer gives directions that conflict with a sign or signal, which must you follow?

Which of the following must you obey over the other three?
  1. A The steady red signal
  2. B The traffic officer’s directions
  3. C The stop sign
  4. D The flashing red signal

Correct answer: B – The traffic officer’s directions

Under Missouri law, drivers must obey official traffic-control devices unless a traffic or police officer directs otherwise. When an officer’s instruction conflicts with a sign or signal, the officer’s direction controls. For example, you must stop if an officer orders you to stop even when the signal is green.
