Ohio Road Signs Practice flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Speed limit sign

White rectangular regulatory sign with black numerals showing the maximum lawful speed under normal conditions. It is not an advisory speed; yellow plaques give recommended curve speeds.

Stop sign shape

Red octagon with white legend reading STOP. Requires a complete stop at the stop line, crosswalk, or roadway edge before proceeding when clear.

Yield sign

Red-and-white inverted triangle. Requires slowing and giving right-of-way to cross traffic; a full stop is needed only when traffic or conditions demand it.

No left turn symbol

Black left-turn arrow inside a red circle with a diagonal slash on a white sign. Left turns are prohibited at that location, including during green lights unless a sign says otherwise.

Lane-use control sign

Overhead or roadside white sign with black arrows showing permitted movements for each lane. A turn-only arrow requires turning from that lane; a straight arrow requires proceeding through.

Advisory speed plaque

Yellow rectangular plaque below a warning sign giving a recommended speed in mph for the condition ahead, such as a curve or ramp. It is advisory, not a legal maximum.

Winding road sign

Yellow diamond showing a squiggly arrow, warning of two or more curves in succession. Slow before the first curve and stay in your lane throughout.

Side road warning

Yellow diamond showing a through road with a smaller road entering from one side. The arrow's position indicates the direction from which traffic may enter.

Lane ends sign

Yellow diamond reading RIGHT or LEFT LANE ENDS, warning that a lane will merge away. Merge early and do not wait until the taper to change lanes.

Steep grade sign

Yellow diamond showing a truck on a slope with a percent grade plaque. Warns of a long downgrade or upgrade; reduce speed and use a lower gear on descents.

Slippery when wet sign

Yellow diamond with a car and skid marks. Warns the pavement loses traction when wet; reduce speed and avoid sudden braking or steering during rain.

Work zone sign color

Orange diamond or rectangle with black legend. Orange marks temporary traffic control for construction and maintenance; speed limits posted there apply while the zone is active.

Flagger authority

A flagger holding a STOP/SLOW paddle has the same authority as a stop sign. Remain stopped until the paddle is turned to SLOW and the flagger waves you on.

Channelizing devices

Cones, drums, tubular markers, and vertical panels that separate traffic from a work area. Do not cross them, even if the lane beyond appears clear.

Type III barricade

Large barricade with alternating orange and white stripes and a sign, used to close a road completely. Do not drive around it; follow the posted detour instead.

Arrow board

Trailer-mounted board of lights in a work zone. A diagonal arrow directs traffic to merge in the direction shown; a bar of lights across the top means the lane is closed.

Interstate route shield

Red, white, and blue shield marking an Interstate highway. U.S. routes use a black-and-white shield; Ohio state routes use a white outline marker on black.

Mile marker

Small green sign along the shoulder giving distance from the route origin or state line. Use the number to report your location to emergency dispatchers.

Service sign color

Blue rectangular sign with white symbols for gas, food, lodging, camping, and hospitals. Blue indicates motorist services available at or near an upcoming exit.

Recreation sign color

Brown rectangular sign with white legend pointing to parks, historic sites, and scenic areas. Brown marks recreation and cultural interest destinations, not services.

Railroad crossbuck

White X-shaped sign with black letters reading RAILROAD CROSSING. Means yield to trains; stop if a train is approaching, and never drive around a lowered gate.

Multiple tracks plaque

Small plaque below a railroad advance warning sign reading 2 TRACKS or similar. Warns that more than one track crosses the road, so a second train may follow the first.

School zone sign

Fluorescent yellow-green pentagon showing children walking. Often paired with a reduced speed limit plaque that applies during posted hours or when children are present.

School bus red lights

Flashing red lights on a stopped school bus require traffic in both directions to stop on an undivided road. On a divided highway, only traffic behind the bus must stop.

Yellow sign meaning

Yellow diamond signs warn of conditions ahead such as curves, intersections, and hazards. They do not change the speed limit but call for reduced speed and attention.

Octagon and triangle shapes

Octagon always means stop; inverted triangle always means yield. These shapes are unique to those signs, so they are recognizable even when snow or dirt obscures the legend.

Red circle and slash

Symbol on a white regulatory sign meaning the pictured action is prohibited, such as no U-turn or no left turn. A red slash alone means no parking.

Yellow line meaning

Yellow pavement lines separate traffic moving in opposite directions. A solid yellow line on your side means no passing; a broken yellow line permits passing when safe.

Double solid yellow line

Two solid yellow lines mean no passing in either direction. Do not cross them except to turn into or out of a driveway or side road where permitted.

Flashing yellow signal

A flashing yellow light means proceed with caution through the intersection. It is not a stop requirement; slow down and check for cross traffic before proceeding.

No turn on red sign

Regulatory sign prohibiting a right turn on red at that intersection. It overrides the general permission to turn right after stopping at a red light.

Crosswalk and stop line

White bars or transverse lines mark the crosswalk; a solid white stop line before it shows where to stop for a signal or sign. Stop behind the line, not on it.
