Louisiana Road Signs and Their Meanings

Louisiana's official guide does something unusual: it coaches you on how to sit the exam. Under the heading "Tips to Pass the Written Test", the Class D & E Driver's Guide advises reading the manual at least three times, memorizing "any numeric information in the manual: lengths, distances, measurements", reading the full question and every option before choosing, and arriving at the licensing office at least an hour before the last test of the day can be given. Then come two lines of a different kind: "Trust your gut instinct" and "Go with the 'safest sounding' answer." That advice earns its keep on a judgment question about following distance or right of way. It earns much less on a sign, where the answer is a fact about what a particular shape and color mean, and the safest-sounding option is often the one written to catch a guess.

Louisiana publishes both halves of this bar, but it takes three of its pages to collect them. The guide's Knowledge Test section says applicants "must correctly answer 80 percent of these questions to receive a passing score"; the Office of Motor Vehicles states on expresslane.la.gov that "an 80% is the minimum passing score for the knowledge test." Neither of those two sentences says how many questions "these questions" are. A third OMV page answers that: its Permits page describes the learner's-permit requirement as a vision check plus "a 40 question test with a minimum score of 80%", which puts the paper at forty items and the pass mark at thirty-two. R.S. 32:408 corroborates the percentage and adds a floor rather than a fixed length, requiring that a Group "D" or "E" knowledge test "shall contain at least thirty-two items". So the forty items with thirty-two right on this page are Louisiana's own figures, not a stand-in of ours — though none of those pages puts a clock on the test. Nothing carves out a sign portion beneath that eighty percent either — but signs do come first when the guide explains what the exam is for. It exists, in the guide's words, to confirm "your understanding of traffic signs and signals, as well as safe driving practices and Louisiana laws relative to driving": signs and signals lead a list of three, and everything on the paper is drawn from the manual itself.

Chapter 3 of the Class D & E Driver's Guide is headed SIGNS, TRAFFIC LIGHTS, AND PAVEMENT MARKINGS, and signs take the largest share of it: TRAFFIC SIGNS opens the chapter on page 22 and runs until TRAFFIC SIGNALS begins on page 33. Two things in those pages catch readers out. The first is a word. In the shape paragraphs Louisiana calls the warning family "yellow diamond shaped signs"; a page later, in the color list, the same family is entered under Amber — "used as background color for warning signs and school signs. Means: Caution, be alert, prepare to slow down." If you have memorized a color list from anywhere else, that entry is not where you will look for it. The second is the crossbuck. Louisiana files the white cross buck under regulatory signs and equates the obligation it imposes with yielding, leaving the advance-warning job to the round yellow sign set back from the tracks. The chapter also carries a family many manuals skip: Incident Signs, fluorescent pink with black lettering, temporary, posted for a crash, a spill, a closure or a detour, and tied in the same paragraph to Louisiana's move-over law.

Color is the one topic in this Louisiana set that turns up twice under two different headings, and that is the guide's doing rather than ours: it names color once inside the run of sign shapes and again in a list of its own further down. The questions here follow both. Read only one of those passages and you will meet the warning family as a yellow diamond in one place and as Amber in the other, which is a genuinely easy way to answer a color question wrongly while believing you studied it. The rest of the set works through the chapter's paragraphs one at a time — shapes, the yield sign, do not enter, wrong way, no turn on red, guide and service signs, signs in construction areas, incident signs, the railroad cross buck — and every published question here stays inside that one chapter. None reaches past the signs into the traffic-signal or lane-marking material that shares the chapter's title, which is worth knowing, because your exam is not similarly bounded.

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