Texas Road Signs and Their Meanings

Texas grades its own shape rules, and the grading is the useful part. Table 17 of the Texas Driver Handbook, headed Signs by Shape, uses the word "exclusively" three times and the word "generally" twice, and the difference is not decoration. An octagon is "exclusively for stop signs"; an equilateral triangle is "exclusively for yield signs"; a diamond is "exclusively to warn of existing or possible hazards on roads or adjacent areas." Those three you can read as absolutes and answer from the outline alone. But a horizontal rectangle is only "generally for guide signs" and a vertical rectangle only "generally for regulatory signs", so a rectangle narrows the field without settling it and you have to read the face. The remaining three shapes carry no hedge and are the ones people forget: pennant for advance warning of no-pass zones, pentagon for school advance and school crossing, round for railroad advance warning.

Texas states its passing standard in one flat line and applies it to everything: "You must score a grade of 70 percent or better to pass any knowledge exam." Any covers all three the handbook lists — the Class C exam for original applicants, the Class M motorcycle exam, and the rules exam for Class A and Class B operators — and not one of them has a published length. The Department of Public Safety describes the exams, prices the licenses and lists the documents, but nowhere states how many questions you will face, how long you have, or how many of those questions will show you a sign. A Texas drill on this page runs thirty items and asks for twenty-one, which is the shape the Class C paper has long been described as having rather than one DPS has ever confirmed; the seventy percent is the half of that sentence you can actually rely on. Nothing beneath that percentage is reserved for signs, which means a run of missed sign questions costs exactly what a run of missed right-of-way questions costs — no more, and no less.

Chapter 5 of the Texas Driver Handbook is called Signals, Signs, and Markers, and its structure tells you where Texas thinks the difficulty lies. The chapter teaches through numbered tables of sign-and-description pairs: Table 16 is Standard Colors, Table 17 is Signs by Shape, Table 18 is Warning Signs and is long enough to carry a Continued header more than once, and Table 19 is Regulatory and Warning Signs. Notice what is missing. Warning signs get a table to themselves and then a second one they share; regulatory signs never get one of their own at all, and the chapter's contents confirm it — Warning Signs opens on page 26 and the next heading, on page 30, is Regulatory and Warning Signs. The color table has its own oddity: Black and White are listed as separate entries carrying the identical one-word description, Regulation, and Orange appears twice, once as the construction-and-maintenance warning color and again as Orange (Retroreflective). Throughout, the descriptions are written as instructions rather than definitions — "Slow down, keep right, and do not pass" — and the chapter credits its pictures to somebody else, noting that some images are courtesy of the MUTCD, 2009 Edition, published by the FHWA.

The title of the signs chapter names three things, and this set covers one of them. Every published Texas question here is about a sign: none asks about a pavement marking, a lane-use control signal, a barrel or a channelizing device, even though all of those sit under the same chapter heading and can be examined the same way. Read that as a boundary rather than as a syllabus, and read the rest of the chapter yourself. Inside the signs, the set divides in two. A small group asks about the grammar, where a shape or a background color is the entire question. The much larger group is warning-sign identification, in which the outline never changes and only the symbol inside it does — a merging arrow, a lane ending, a leaping deer, a tractor, a plus-shaped intersection. Getting through the second group is a matter of reading symbols, because by then the outline has already told you everything it can.

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