Nebraska Road Signs and Their Meanings

Driver licensing in Nebraska runs through the Nebraska Department of Motor Vehicles, and the book it hands you is the Nebraska Driver's Manual — the Class O edition dated January 2025, a ninety-two-page PDF posted on dmv.nebraska.gov. It opens with a letter from Governor Jim Pillen that describes the roads the signs later have to warn you about: "In Nebraska, weather conditions change unexpectedly, paved roads give way to gravel, and speeds drop sharply when approaching town." What the book never does, front to back, is put a number on the exam. It does not say how many questions the Class O written test asks, and it never states a passing mark; the word "score" does not occur in it once. No page on dmv.nebraska.gov supplies either figure either. The one measurement the DMV does publish about its written test is an uncomfortable one, sitting in the tips list near the front of the manual: "Over 32% of first-time applicants fail the written test." So the honest starting point for a Nebraska candidate is that the size of the exam is private and the failure rate is not.

Nothing in Nebraska's rules sets aside part of the written test for signs, and there is no published breakdown for such a rule to sit inside. The manual's testing section offers scope instead of structure: "There is a separate written test for each class of license," and the material needed to pass the Class O test "can be found in this manual." Signs are unambiguously inside that scope — the section carrying them opens by calling them non-negotiable, "A thorough knowledge of traffic signs, signals and road markings is a must for all drivers." How many of them reach your screen is simply not stated. The DMV's own online practice examination shows why the question has no answer. That tool says outright that "The questions and answers used in this practice test come from the same pool of questions as the actual test administered at the DMV," and then hands the length of the session to you: a two-character box labeled "Number of questions to ask," whose placeholder reads "Leave blank for unlimited." An exam you size yourself cannot reveal the size of the real one, and Nebraska fills in that blank nowhere else.

Where the manual repays a careful reader is its numbering. Signs sit in Section 3, Signs, Signals and Markings, under the heading 3B Traffic Signs, which runs from page 34 to page 43 between 3A Traffic Signals and 3C Pavement Markings. 3B is then cut into six labeled subsections — 3B-1 Sign Colors, 3B-2 Sign Shapes, 3B-3 Regulatory Signs, 3B-4 Warning Signs, 3B-5 Special Signs and 3B-6 Work Zone Devices — so a reader can be pointed at an exact heading instead of a chapter. 3B-1 is a color-to-meaning list, and a long one: red, yellow, yellow-green, pink, green, blue, white, orange and brown each get a line, with pink assigned to incident management and yellow-green reserved for warnings about pedestrians, bicycles, playgrounds, schools and school buses. 3B-2 does the same job for shape, and includes the rectangle rule that catches people out — "When vertical, signs are generally used to give instructions or tell you the law. When horizontal, signs give directions or information." Deeper in, 3B-5 gathers the outliers, among them the Reference Post Marker, which the manual places "on Nebraska highways in one mile increments to serve as a reference point for drivers to use when assistance is needed, or an emergency exists," and the slow-moving vehicle emblem required of anything traveling 25 MPH or less, farm equipment included. 3B-4 ends on a quiet-zone sign, No Train Horn, posted where trains do not sound the horn at all. 3B-6 boils work zones down to one memorable line: "Remember, black-on-orange signs identify work zones."

Every published Nebraska sign question here cites the manual and then one of those labeled subsections by name, so an explanation you disagree with can be checked against the exact heading it came from rather than against a whole chapter. The weight is not spread evenly across them. Most of the set gathers in the two subsections at the front of the traffic-signs material — the one mapping color to meaning and the one mapping shape to meaning — and the remainder reaches out into warning signs, special signs and work-zone devices. That skew belongs to Nebraska's book rather than to any preference of ours. Those opening subsections are written as rules in sentences, so they can be asked and answered in words alone, while much of what follows is a gallery of captioned pictures that needs the picture to make sense. Read the front of the traffic-signs material closely and the rest as a tour, and you will be studying the way the citations already point. Do not treat the thinner subsections as optional, though: the manual puts real obligations in them, and the questions do reach that far.
