Kentucky Road Signs and Their Meanings

The written test you sit in Kentucky is given to you by the Kentucky State Police. Not a motor-vehicle department, not a licensing bureau — troopers. You start at a Kentucky Transportation Cabinet Regional Driver Licensing Office, which prepares the application, and from there the manual is explicit that "the Kentucky State Police will administer all required tests." The driver manual is itself a State Police publication, carrying the KSP commissioner's name, and every written and road test runs by appointment through the KSP scheduling system. Kentucky publishes the score you must reach — "applicants must make a minimum score of 80% to pass this test" — but nowhere publishes how many questions that eighty per cent is measured against.

Kentucky's manual treats the sign questions as a distinct portion of the written test, and it says so in an unexpected place: the rules on accommodation. "Tests can be given orally for applicants who cannot read the English language," it reads. "However, the signs portion of the test must be answered by applicants from their own knowledge and understanding." That sentence does two things at once. It confirms a signs portion exists inside the single eighty per cent score, and it withdraws, for that portion alone, the help offered everywhere else on the paper. An applicant testing through an interpreter or an oral administration still meets the sign questions unaided. The manual never says how many of them there are — but it has told you exactly which questions nobody is permitted to carry you through.

The sign material lives in Section Six: Rules of the Road, where Kentucky compresses the fundamentals into two labeled tables a page apart. STANDARD COLORS assigns three colors a job each — red for stop or forbidden, green for movement permitted and directional guidance, yellow for general warning. STANDARD SHAPES sets out six shapes: horizontal rectangle, equilateral triangle, vertical rectangle, diamond, pentagon and round. The other colors are not in that table. They arrive attached to the sign families that use them, so work zone signs are introduced as "generally diamond or rectangular shaped and orange with black letters or symbols" and guide signs as "square and rectangular and are green, brown, or blue." Anyone studying from the tables alone will be short of colors; the families are where the rest of the system is kept.

Begin with the three questions cited simply to Traffic Signs, because they are the ones that assume no preparation at all: what an eight-sided red sign demands of you, how a driver recognizes a yield sign, and what most signs warning of a hazard ahead look like. Nothing about those is Kentucky-specific, which is exactly why they are worth clearing first. The regulatory group is the largest single one here — a wrong-way sign, a do-not-enter sign, a shared center lane reserved for left turns, a black-and-white speed limit sign, all of them signs that state a law rather than describe a hazard. What remains divides between the standard-shapes table and railroad crossings, then one question each on guide signs, work zone signs and the slow-moving vehicle emblem. No group here is a majority, so no group is safe to skip.

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