Kentucky Road Signs Practice key terms

A white rectangular regulatory sign with black numerals showing the maximum lawful speed in miles per hour. It applies from the sign until another limit or a different zone begins.

A sign that states a law or rule drivers must obey, such as a stop, yield, speed limit, or lane-use requirement. Most are white rectangles with black, red, or green markings.

A red octagon with white letters requiring a complete halt at the stop line or crosswalk. The driver yields to traffic and pedestrians before proceeding when the way is clear.

A stop-controlled intersection where every approach has a stop sign, usually with a small plaque below it. Vehicles proceed in the order they arrived, with ties resolved by yielding to the right.

A downward-pointing red and white triangle telling drivers to slow down and let crossing or merging traffic go first. A full stop is required only when traffic or pedestrians make it necessary.

A section of road, marked by solid yellow center lines or regulatory signs, where passing another vehicle is prohibited because sight distance or road design makes it unsafe.

A sign or signal that assigns specific directions or vehicle types to each lane, such as left-turn-only or bus-only lanes. Drivers must be in the correct lane before the restriction begins.

An overhead signal, often a green arrow or red X, that shows whether a lane is open or closed to traffic in the current direction. Drivers must never enter a lane showing a red X.

A signal mounted above a travel lane, used in toll plazas, tunnels, and managed lanes, that indicates whether that lane is open, closed, or restricted to certain vehicles.

A sign limiting when, how long, or for whom parking is allowed, such as time limits, permit-only zones, or no-parking areas. Ignoring it can result in a citation or towing.

A blue and white sign reserving a space for vehicles displaying a valid disability placard or plate. Unauthorized use of the space or placard is a violation in Kentucky.

A yellow diamond sign that alerts drivers to a change in road conditions, alignment, or traffic ahead. It does not state a law but tells drivers to slow down or prepare to react.

A yellow rectangular plaque mounted below a warning sign that shows a recommended speed for the hazard, such as a sharp curve. It is a suggestion, not the legal speed limit.

A yellow diamond warning sign showing an arrow that bends left or right to indicate a curve ahead. A variant with a reverse bend warns of a series of curves.

A rectangular yellow sign with a black arrow shape placed in a curve to guide drivers through the turn. It supplements the advance curve warning and marks the direction of travel.

A yellow diamond sign with a cross, side-road, or T symbol alerting drivers to an approaching intersection. It is common where the crossing traffic may not be obvious from a distance.

A yellow diamond sign showing two arrows joining into one, warning that traffic from another lane or ramp will enter the roadway. Drivers should adjust speed and make room.

A yellow diamond sign with a walking figure warning that pedestrians may cross ahead. Drivers must slow down and yield to anyone in the crosswalk.

A yellow-green diamond or pentagon sign marking an area where children travel to and from school. Reduced speed limits apply during posted hours or when lights flash.

A yellow diamond sign warning that the pavement loses traction in rain or wet conditions. Drivers should slow down and avoid sudden braking or steering.

A sign that gives directions, distances, route numbers, or destinations rather than stating a rule. Guide signs are typically green, blue, or brown and help drivers navigate.

A sign identifying a numbered highway, such as an interstate shield or a state route outline. It helps drivers confirm they are following the intended road.

A small green sign along a highway showing the distance in miles from a reference point, often a state line. It helps drivers report their location in an emergency.

A blue sign listing nearby facilities such as fuel, food, lodging, or hospitals, often with exit distances. It helps drivers plan stops without leaving the highway.

The red, white, and blue shield-shaped marker identifying an Interstate highway. Even-numbered routes generally run east-west and odd-numbered routes generally run north-south.

An orange sign warning of construction, maintenance, or utility work ahead. Orange means temporary conditions, so drivers should slow down and expect lane changes.

A marked area where construction or maintenance changes normal traffic flow, often using cones, barrels, and channelizing devices. Speed limits may be reduced and penalties for violations increased.

A trained worker who uses a paddle or hand signals to stop and release traffic through a work zone. Drivers must obey the flagger's directions even if a signal or sign says otherwise.

A cone, drum, or barricade used to guide traffic around or away from a work area. Drivers should stay within the marked path and not cross these devices.

A reduced speed limit posted in a construction or maintenance area, often with higher fines for violations. The lower limit applies even when workers are not visible unless signs say otherwise.

The convention that a sign's outline conveys its purpose, such as octagon for stop, triangle for yield, and diamond for warning. Recognizing shapes helps drivers react quickly.

The standard use of color on signs: red for prohibitions, yellow for warnings, orange for work zones, green for guidance, blue for services, and brown for recreation areas.

Painted lines and symbols on the road surface that guide or regulate traffic. Yellow lines separate opposing directions, while white lines separate lanes moving the same way.

A line marking the outer boundary of a travel lane, typically white on the right and yellow on the left of a divided highway. It helps drivers stay on the roadway in poor visibility.

A signal head with red, yellow, and green lights controlling traffic at an intersection. A steady red means stop, yellow means prepare to stop, and green means proceed when clear.

A signal that blinks instead of showing steady lights, such as a flashing red or flashing yellow. Flashing red is treated like a stop sign; flashing yellow means proceed with caution.

A white X-shaped sign with black lettering marking a railroad crossing. Drivers must yield to trains, and a crossbuck with a stop sign or gate requires a full stop.

A yellow round sign with a black X and two R's placed before a railroad crossing. It warns drivers to slow down, look, and listen for an approaching train.

A signal with flashing red lights, and often a gate, at a railroad crossing. Drivers must stop when the lights flash or the gate lowers and never drive around a lowered gate.

The flashing red lights and stop arm displayed by a school bus loading or unloading children. Traffic in both directions must stop unless separated by a median or barrier.
