Road signs get their own spotlight on the Missouri driver exam, and that is the part many new drivers do not realize until they start looking at the actual testing process. The full Missouri driver examination includes the written knowledge test, vision test, road sign test, and driving skills test. You have to pass the written, vision, and sign portions before the driving skills test is even available, so sign knowledge is not just extra study material. It is one of the required steps. This Missouri DMV practice test is built around that road sign portion of the process. It gives you 20 multiple-choice questions based on the Missouri Driver Guide and the sign standards drivers are expected to understand, including shapes, colors, symbols, regulatory signs, warning signs, guide signs, traffic signals, and pavement markings. To pass this Missouri road signs test, you’ll need at least 16 correct answers. That 80% target should sound familiar, since Missouri’s Class F written knowledge test also uses an 80% passing score. The licensing setup is a little split, which is boring but useful to know. The official Class F instruction permit knowledge test is administered by the Missouri State Highway Patrol, while permits and licenses are issued by the Missouri Department of Revenue. The written test is separate from the road sign test. It has 25 multiple-choice questions, is not open book, and requires 20 correct answers to pass. It covers Missouri traffic laws, safe driving, rules of the road, roadway markings, sharing the road, alcohol and drug rules, distracted driving, electronic communication device rules, and basic vehicle operation topics from the Driver Guide. This Missouri permit practice test keeps the focus tighter: road signs, what they mean, and how confidently you can recognize them without overthinking every answer. That matters because signs often give you information before the words fully land. Shape, color, placement, and symbol all carry meaning. And yes, Missouri-specific details still belong in your study routine, including the rule about signaling at least 100 feet before making a turn. Work through the questions without the pressure of the official exam, notice the ones that slow you down, and use this practice as a calmer way to sharpen your road sign knowledge before test day.

Sample Missouri Permit Test Questions

Question 1

What must you do before turning right at a steady red light where the turn is not prohibited?

  1. A. Stop completely and yield to pedestrians and other traffic
  2. B. Turn immediately if a red arrow is displayed
  3. C. Slow down without stopping
  4. D. Turn before pedestrians enter the crosswalk

Correct answer: A. – Stop completely and yield to pedestrians and other traffic

A driver must first stop at the stop line, before the near crosswalk, or before entering the intersection, as applicable. The driver may then cautiously turn right while yielding to pedestrians and traffic proceeding under the signal. A posted prohibition on turning right on red must be obeyed.

Source: Mo. Rev. Stat. § 304.281.1(3)(a)–(b) — Rules for traffic where controlled by light signals — right turn on red light, when — violations, penalty

Question 2

At an unsignalized approach, a DIVIDED HIGHWAY CROSSING sign means:

This sign means:
  1. A. The road ends at a T-intersection
  2. B. The road crosses over a divided highway
  3. C. You are approaching an intersection with a divided highway
  4. D. The divided section of your road is ending

Correct answer: C. – You are approaching an intersection with a divided highway

Missouri’s engineering guidance uses the Divided Highway Crossing sign on certain unsignalized minor-street approaches. It advises drivers that they are approaching an intersection with a divided highway. At these locations, the separate roadways of the divided highway may function as two intersections.

Question 3

Fluorescent orange traffic signs generally indicate:

  1. A. Work is being performed on or alongside the roadway
  2. B. Motorist services are available ahead
  3. C. A permanent route change begins ahead
  4. D. A hospital or first-aid station is nearby

Correct answer: A. – Work is being performed on or alongside the roadway

In Missouri, fluorescent orange signs identify work being performed on or alongside the roadway. A work zone may also contain lane restrictions, equipment, workers, flag persons, or other traffic-control devices. Obey the posted instructions and pay close attention while traveling through the area.

Question 4

A white regulatory sign showing a right-turn arrow inside a red circle and slash means:

This sign means:
  1. A. No U-turn
  2. B. No left turn
  3. C. No right turn
  4. D. No turns in either direction

Correct answer: C. – No right turn

This is the No Right Turn sign. Regulatory signs with a red circle and diagonal slash prohibit the action displayed by the symbol. A driver must not make a right turn where this sign applies.

Question 5

Which use is permitted for a marked two-way left-turn lane?

From the center lane, what maneuvers can you perform?
  1. A. Preparing to slow or stop before a left turn from the main roadway
  2. B. Passing a slower vehicle
  3. C. Continuing through traffic as in an ordinary travel lane
  4. D. Entering the main roadway from a side street

Correct answer: A. – Preparing to slow or stop before a left turn from the main roadway

In Missouri, enter a two-way left-turn lane when preparing to slow or stop before turning left from the main roadway. A U-turn may also begin there when that maneuver is otherwise permitted. Do not use the lane for passing or ordinary travel; the Driver Guide limits travel in it to 500 feet and says not to use it when entering from a side street.

Question 6

A yellow diamond-shaped Merge sign indicates that:

This sign means:
  1. A. Two-way traffic begins ahead
  2. B. Another lane is being added without a merge
  3. C. Traffic from another road may move into your lane
  4. D. A divided roadway begins ahead

Correct answer: C. – Traffic from another road may move into your lane

A Merge sign warns that traffic from another road will be entering the roadway and may move into your lane. Be prepared for the entering vehicles. An Added Lane sign is different because it indicates that a new lane begins and an immediate merge is unnecessary.
