Ohio Road Signs Practice key terms

A white rectangular sign with black numerals showing the maximum lawful speed in miles per hour under normal conditions; driving faster is a violation even if traffic or weather seems to invite it.

A red octagon with white letters requiring a complete halt at the stop line, crosswalk, or edge of the intersecting roadway before proceeding only when the way is clear.

An inverted red-and-white triangle meaning you must slow or stop as needed and let cross traffic and pedestrians go first; you proceed only when no conflict exists.

A sign that states a law or requirement, such as a speed limit, turn restriction, or lane use rule; typically white with black or red markings and enforceable by citation.

A white square sign with a black arrow and red slash circle forbidding the shown turn, such as no left turn or no U-turn, at that location at all times unless a plaque states otherwise.

An overhead or roadside sign assigning a lane to a movement or vehicle type, such as left turn only or bus only, telling drivers which lane to choose before the intersection.

A black horizontal arrow on white marking a street where all traffic moves in the arrow's direction; entering against it is wrong-way driving even if the lane looks empty.

A red circle with a white horizontal bar and the words DO NOT ENTER, posted at the exit of one-way roads and ramps to warn that oncoming traffic is approaching head-on.

A red square sign reading WRONG WAY placed inside a one-way roadway or ramp to tell a driver who has already turned the wrong direction to stop and back out.

A sign restricting standing or leaving a vehicle at the curb, often with times or days on a plaque; stopping briefly to load passengers may still be allowed unless the sign says no standing.

A blue-and-white sign reserving a space for vehicles displaying a valid disabled placard or plate; unauthorized use can bring a fine and towing in most jurisdictions.

A yellow diamond sign alerting drivers to a condition ahead, such as a curve, hill, or crossing; it does not state a law but calls for reduced speed and attention.

A yellow rectangular plaque under a warning sign giving a recommended speed for the hazard, such as 25 MPH through a curve; the posted limit still applies but the advisory is the safe target.

A yellow rectangular sign with a black arrow pointing the direction of a sharp curve, placed along the outside of the bend to guide drivers who misjudge the turn.

A yellow diamond showing a curving arrow, with a plaque noting right or left, warning of a bend ahead where speed should be reduced before entering the curve.

A yellow diamond showing a sloped road with a percentage, warning of a steep downgrade where trucks should gear down and drivers should expect slower traffic ahead.

A yellow diamond showing a car with skid marks, warning that the surface loses traction in rain or snow; reduce speed and avoid sudden braking or steering on the wet patch.

A yellow diamond showing a road whose edges pinch inward, warning that lanes or shoulders shrink ahead so drivers should merge early and check for vehicles beside them.

A yellow diamond showing an arrow joining a through road, warning that an entering lane must blend with traffic; entering drivers yield and through drivers should make room.

A yellow diamond showing a lane tapering away, warning that the lane will disappear and drivers in it must merge; signs may add a distance plaque such as 1000 FEET.

An orange diamond or rectangle warning of construction or maintenance activity ahead, often paired with reduced speed plaques and requiring extra caution for workers and equipment.

A trained worker holding a STOP/SLOW paddle who controls one-lane traffic through a work zone; drivers must obey the paddle exactly as they would a signal or an officer.

A cone, drum, tubular marker, or barricade used to guide traffic around a work area or divide lanes; hitting one signals a driver has left the intended path.

A sturdy orange-and-white or striped barrier closing a road or lane, often with a Type I, II, or III rating; it marks a path that is physically blocked, not merely discouraged.

A green, blue, or brown sign giving directions, destinations, distances, or services rather than rules; green covers routes and exits, blue covers services, brown covers recreation and parks.

A shield or geometric sign identifying a numbered highway, such as an Interstate shield or a state route outline, helping drivers follow a route through turns and interchanges.

A small green sign with a number showing the distance along a highway from its starting point; useful for reporting a breakdown or crash location to dispatchers and responders.

A white X-shaped sign with the words RAILROAD CROSSING marking the tracks themselves; drivers must yield to trains, and a second crossbuck means multiple tracks.

A yellow round sign showing a black X and two R letters, placed ahead of tracks to warn that a crossing is coming and that a stop may be required.

Flashing red lights, a lowering gate, or both at a crossing; a driver must stop and never drive around a lowered gate or enter while lights flash, even if no train is visible.

A yellow pentagon or fluorescent yellow-green sign marking an area where children cross and speeds are reduced during posted hours; fines often double when workers or children are present.

A sign showing a lower limit that applies only during stated times or when yellow lights flash near a school; outside those times the regular limit governs.

A yellow diamond or fluorescent yellow-green sign showing a walking figure, warning that pedestrians cross ahead; drivers must yield to anyone in the crosswalk.

The meaning carried by a sign's background: red for stop or prohibition, yellow for warning, orange for work zones, green for guidance, blue for services, brown for recreation, white for regulation.

The meaning carried by a sign's outline: octagon for stop, inverted triangle for yield, diamond for warning, pentagon for school, round for railroad advance warning, rectangle for regulation or guidance.

Painted lines and symbols on the road surface that supplement signs, such as yellow center lines, white edge lines, arrows, and crosswalk bars; they carry the same legal force as signs.

White or yellow arrows painted in a lane showing its permitted movement, such as a left-turn arrow; they tell drivers to be in the correct lane before reaching the intersection.

White parallel bars or two transverse lines marking where pedestrians cross; drivers must yield to pedestrians in them, and passing a vehicle stopped at one is dangerous and often illegal.

A solid white bar across a lane showing where to halt for a stop sign or signal; stopping past it, or inside a crosswalk, can block pedestrians and violate the law.

Electric red, yellow, and green lights controlling right-of-way; a sign may modify the signal, such as no turn on red, and the sign controls when the two appear together.

A regulatory sign forbidding a right or left turn while the signal is red, overriding the general permission to turn after stopping; posted where visibility or pedestrians make the turn unsafe.
