The Kentucky Driver Licensing permit knowledge exam reserves a substantial portion of its questions for road sign recognition. This guide covers the four sign families you will see on the test and on the road in Kentucky: regulatory, warning, guide, and work zone.
Regulatory signs
Regulatory signs in Kentucky are typically white rectangles with black or red lettering. They communicate enforceable traffic laws. The most common are the eight-sided red stop sign, the downward-pointing red and white yield sign, the white speed limit signs that establish the legal maximum, the white do not enter sign, the no turn on red sign, and the one way arrows that establish lane direction. Kentucky disobeying any regulatory sign is a moving violation that adds points to your driving record.
Warning signs
Warning signs are yellow diamonds with black symbols and occasionally text. They warn of conditions ahead such as curves, hills, deer crossings, narrow bridges, slippery roads, intersections, and pedestrian crosswalks. The number on a yellow curve sign is an advisory speed for the curve, not the legal limit. Kentucky also uses yellow pentagons specifically for school zones and yellow pennants on the left side of the road for no passing zones.
Guide and information signs
Green signs in Kentucky provide directional information for highways, exits, and destinations. Blue signs identify motorist services such as fuel, food, lodging, and rest areas. Brown signs identify recreational and cultural sites. On limited-access highways, the standard sequence is a one mile advance sign, a half mile sign, and the exit direction sign at the gore point.
Work zone signs
Orange diamonds and rectangles indicate temporary traffic control through construction and maintenance zones. Kentucky doubles fines for moving violations in posted work zones whether or not workers are present. Reduce speed, increase following distance, and obey flagger instructions, which legally override conflicting signs and signals.
