Tennessee Road Signs and Their Meanings

Tennessee tells you roughly how much of the knowledge test is about signs, which is not a figure every state is willing to put in writing. Under the heading The Examinations, the Comprehensive Driver License Manual says you can expect the test to approximately consist of four areas, each at a quarter: traffic signs and signals, safe driving principles, rules of the road, and drugs and alcohol. Read that carefully before you plan around it. It is an expectation rather than a rule, the word approximately is the department's own, and the quarter covers signals as well as signs. Even so, it is a real published figure, and it makes signs one of the four things Tennessee expects you to walk in knowing.

Only one of those four quarters is a legal requirement, and it is not the sign quarter. Deeper into the same manual, in the chapter on alcohol and other drugs, Tennessee states that by law at least 25 percent of the questions on the knowledge test must consist of questions dealing with that topic. So one quarter is a floor written into law and the other three, signs included, are the department's own estimate of the paper. The test itself is documented in detail for the version teenagers aged fifteen to seventeen can take at home under a parent or guardian's supervision through the Tennessee Proctor ID app: thirty questions, sixty minutes, a minimum score of 80 percent, and English or Spanish. The rules around it are strict. Navigating away from the test window is an automatic failure. At the thirty-minute mark the supervising adult must re-authenticate by scanning a QR code, and failing to do so is also an automatic failure. Applicants get two online attempts, with twenty-four hours between them.

Signs are Chapter 3 of Section B of the manual, titled Traffic Signs and Signals, and Tennessee teaches them shape first. Almost every heading in the chapter is a shape with its meaning welded on: Octagon Shape — Stop. Triangular Shape — Yield. Round Shape — Railroad Ahead. Broad X Shape — Railroad Here. Diamond Shape — Hazardous Or Unexpected Condition Ahead. Rectangular Shape — Special Laws, Regulations or Important Information. The color codes that precede them carry an instruction worth having in advance, printed as a standalone note: whenever white is specified as a sign color, that includes the silver-colored reflective coating and other materials that reflect white light. Two colors get shouted at you. Fluorescent yellow-green is announced in capitals as the color for school zones, and fluorescent pink — sometimes called coral, the manual adds — is reserved for incident management around crashes, wildland fires, floods and hazardous material spills.

Look at the citations under the published Tennessee questions here and you will notice how far down some of them reach. Eight of the twenty name a single sign rather than a section: the object marker, the advisory speed plate, the interstate route marker, the reverse turn sign, the no-passing pennant, the slow-moving vehicle emblem and the two railroad shapes. That is not tidiness on our part, it is the chapter's own structure — Tennessee gives each of those its own heading, so a question drawn from one of them can be cited to the paragraph rather than to the section, and checking the answer takes a page turn instead of a search. The other citations sit higher up, as they should. Six point at the color and shape section, because asking what fluorescent pink means is asking about the whole system rather than about one sign, and the remainder point at a family heading — warning, guide, regulatory — or at the heading the chapter opens on. Those are the questions where you will read a page rather than a paragraph to find the sentence the answer came from.
