Quick reference

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.

Quick reference

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.
