Missouri Road Signs and Their Meanings

In Missouri the road sign test is not something you pass once and leave behind. The Missouri Driver Guide sets it out under renewals in a single flat sentence: each time you renew, you will be required to take the vision and road sign test. It applies to a driver who has held a license for thirty years. It applies when you move here from another state and the written test is waived — then the vision and road sign tests are the only two you take. It even applies while a non-commercial driving privilege is suspended, because Missouri lets you renew during a suspension on the strength of those two tests. Whatever else changes between one license and the next, the sign test comes back around.

The road sign test is one part of a four-part driver examination — written, vision, road sign, driving — and the Driver Guide's entire published description of it is one sentence: the road sign test will check your ability to recognize and understand traffic signs. There is no count, no pass mark and no time limit attached to it anywhere in the guide. The written test beside it is documented far more precisely: twenty-five multiple-choice questions, twenty correct to pass, not an open-book test, and every question drawn directly from the guide with, as the Department of Revenue puts it, no trick questions. The guide offers no time limit for that one either, and just ahead of its driver-examination chapter it prints a blunt warning: almost 50 percent of all test-takers fail the first time.

Two agencies stand behind the Missouri exam and they are not the same one. The Department of Revenue writes and publishes the Driver Guide and issues the license; the Missouri State Highway Patrol administers the examination, through a Driver Examination Division that runs testing stations in every county of the state and warns in capitals that arriving before closing time does not guarantee you will be tested. The signs themselves are Chapter 7 of the guide, headed Pavement Markings, Traffic Signs, and Signals — three subjects under one number, so the sign pages open only after the lane-marking and traffic-signal material is done. When they do open, Missouri lays out shapes and colors as two blunt lists of equations. Octagon equals stop. Pennant equals no passing zone. Crossbuck equals railroad. Yellow green equals school. Brown equals public recreation and cultural interests.

Because of the renewal rule, the reader most likely to need this set is not a teenager. It is someone who has driven in Missouri for years and has a license coming up for renewal, or a new resident who has been told the written test is waived and the sign test is not. That reader does not need the whole guide; they need the part of the signs chapter a Missouri examiner will actually point at, and they need it to be checkable. So each published Missouri question here names the chapter it was drawn from and explains why its answer is right, which lets a driver who last thought about a pennant sign a decade ago go and confirm it in the state's own book rather than take our word for it.

28 published Missouri road-sign questions, each with an explanation and a citation to the handbook section it came from.
