Kentucky Road Signs Practice cheat sheet
Kentucky Road Signs Practice · Keep the key ideas within reach.
Regulatory Signs
Regulatory signs are white rectangles with black legends and tell drivers what they must or must not do; failing to obey one is a citable violation, not a suggestion.
Speed limit signs show the maximum lawful speed in ideal conditions; a posted limit is a ceiling, and drivers must still slow below it for rain, ice, fog, or traffic.
STOP requires a complete halt at the stop line, crosswalk, or edge of the traveled way before proceeding; rolling stops are violations.
YIELD requires slowing and giving the right-of-way; stop only if necessary, and a yield sign at a ramp means merging traffic must wait for a gap.
Lane-use control signs (turn-only arrows, straight-only arrows, center left-turn lanes) assign a mandatory movement to a lane; entering that lane commits the driver to the posted movement.
NO PASSING ZONE pennants and solid yellow lines on the driver's side mean passing is prohibited; a broken yellow line permits passing when safe and legal.
Parking signs restrict by time, day, and permit; a red-slash circle means no parking at any time, while green or white time limits allow posted-duration parking.
One-way and divided-highway signs direct traffic flow; a WRONG WAY or DO NOT ENTER sign marks an exit ramp or one-way lane where entry is illegal.
Warning Signs
Warning signs are yellow diamonds with black symbols; they alert drivers to a change in conditions ahead and call for reduced speed or added caution.
A curve sign with an advisory speed plaque means the safe speed for the curve is the plaque value, which may be below the posted limit.
Intersection warning signs (crossroad, side road, T-intersection) indicate a junction ahead where traffic may enter or cross the driver's path.
Pedestrian and school crossing signs are yellow-green pentagons or yellow diamonds; a school zone speed limit applies during posted hours or when children are present.
Road-condition warnings include slippery when wet, loose gravel, falling rocks, and uneven pavement; each signals a surface hazard requiring reduced speed.
Winding road, hill, and narrow bridge signs warn of geometry changes; downgrade signs may include a grade percentage and a truck escape-ramp note.
A deer crossing or animal warning sign means wildlife may be on the roadway, most often at dawn and dusk; reduce speed and scan shoulders.
Chevron alignment signs (black on yellow) mark the outside of a sharp curve and show the direction of the turn; they supplement, not replace, the curve warning.
Guide and Informational Signs
Guide signs are green with white legends on freeways and indicate destinations, distances, exits, and route numbers.
Interstate route markers are red, white, and blue shields; U.S. routes are black-and-white shields, and state routes use a state-specific marker.
Mileposts are small green markers along the shoulder that give the route mile location; they are used to report emergencies and locate incidents.
Exit signs show the exit number, destination, and distance; an exit number with a letter suffix (e.g., 12A) means multiple exits share one interchange.
Service signs are blue with white symbols (fuel, food, lodging, hospital, rest area) and appear in advance of the service location.
A white rectangular sign with black text is regulatory or informational; a brown sign marks recreation and cultural points of interest.
A yellow or orange exit-only panel means the lane must exit; a green panel with an arrow indicates an optional or mandatory lane movement.
Reassurance markers repeat the route shield and direction (north, south, east, west) so drivers can confirm they remain on the correct route.
Construction and Work Zone Signs
Work zone signs are orange diamonds with black legends; orange distinguishes temporary traffic control from permanent yellow warnings.
A flagger sign (orange diamond with a flagger symbol) means a person controls traffic ahead; obey the flagger's signals over any conflicting sign or signal.
Channelizing devices include cones, drums, and barricades; they define the travel path and must not be crossed or struck.
A reduced-speed plaque in a work zone sets a temporary limit that applies even when workers are not visible, unless the sign states otherwise.
Lane-closure signs and arrow boards shift traffic; a flashing arrow board directs merging in the direction of the arrow.
A ROAD WORK AHEAD sign warns of construction; a DETOUR sign directs traffic onto an alternate route, often marked with temporary route markers.
Work zone speed limits are enforceable; fines may be doubled when workers are present, and the posted temporary limit replaces the permanent one.
Pilot cars and one-lane-two-way operations require following the pilot vehicle and not passing within the controlled section.
Sign Shapes, Colors, and Symbols
Red means stop, yield, or prohibition; white means regulation; yellow means warning; orange means construction; green means guide; blue means services; brown means recreation.
An octagon is used only for STOP; an inverted triangle is used only for YIELD; a pennant marks a no-passing zone.
A yellow diamond is a warning; a yellow-green pentagon marks school zones and school crossings; a round sign marks a railroad advance warning.
A crossbuck (X-shape) marks a railroad crossing; a white X with black letters is the standard passive warning device.
Pavement markings: solid white lines separate same-direction lanes, solid yellow lines separate opposite directions, and broken lines permit crossing when safe.
A double solid yellow line prohibits passing in both directions; a solid yellow on the driver's side with a broken line on the other permits passing only for the broken-line side.
Signal meanings: steady red means stop; flashing red means stop then proceed when clear; flashing yellow means proceed with caution; a green arrow means a protected movement.
A white stop bar and crosswalk lines mark where vehicles must stop for signals and pedestrians; a solid white edge line marks the right edge of the roadway.
Railroad and Special-Purpose Signs
A round yellow advance railroad warning sign with a black X and R/R letters appears before the crossing; it is placed at a distance based on the posted speed.
A crossbuck at the crossing means yield to trains; a train has the right-of-way, and a crossbuck with a stop sign below requires a full stop before crossing.
Flashing red lights and a lowering gate mean stop; never drive around a lowered gate or enter when lights are flashing, even if no train is visible.
A white X-shaped sign reading 3 TRACKS or similar indicates the number of tracks; multiple tracks mean a second train may follow the first.
School bus warning: yellow flashing lights mean the bus is preparing to stop; red flashing lights and an extended stop arm mean traffic must stop in both directions unless separated by a median.
Emergency vehicle signals: a moving emergency vehicle with lights and siren requires yielding and pulling to the right; do not follow within 500 feet.
A blue or white sign with a wheelchair symbol marks accessible parking; misuse is a citable offense and may carry enhanced fines.
A white rectangular sign with black text reading DO NOT PASS or a yellow pennant may accompany railroad or hazard zones; obey the stricter of the posted controls.
Regulatory Signs
Speed limit signs display the maximum lawful speed in ideal conditions; drivers must reduce speed below the posted limit when weather, visibility, or traffic requires.
A STOP sign requires a complete halt at the stop line, crosswalk, or edge of the traveled way before entering the intersection.
A YIELD sign requires slowing and giving right-of-way; stop only when necessary to avoid conflict with cross traffic.
Lane-use control signs assign mandatory movements to lanes; a turn-only arrow means the driver must turn from that lane.
A NO PASSING ZONE pennant combined with a solid yellow line on the driver's side prohibits passing.
Parking signs restrict by time, day, and permit; a red circle with a slash means no parking at any time.
One-way and divided-highway signs direct traffic flow; DO NOT ENTER and WRONG WAY signs mark illegal entry points.
Warning Signs
Warning signs are yellow diamonds with black symbols and alert drivers to changed conditions ahead.
