Quick reference

Regulatory Signs

  • Regulatory signs tell drivers what they must do or must not do; they are enforceable rules, not suggestions.

  • White background with black legend and black border marks most regulatory signs, such as speed limits and turn restrictions.

  • Red and white signs carry prohibitions: STOP, YIELD, DO NOT ENTER, and WRONG WAY all use red as the commanding color.

  • A red circle with a diagonal slash over a black symbol means the action or vehicle type is prohibited.

  • Speed limit signs show the maximum lawful speed in miles per hour under normal conditions; lower posted limits apply in work and school zones.

  • A black-and-white ONE WAY arrow sign indicates traffic flows only in the arrow direction; facing arrows warn of opposing one-way flow.

  • YIELD requires slowing and giving the right-of-way; stop only if traffic, pedestrians, or a safe gap requires it.

  • STOP means a complete halt at the stop line, crosswalk, or edge of the roadway before proceeding when clear.

  • A red octagon always means STOP and a red-and-white downward triangle always means YIELD, regardless of legend.

Quick reference

Warning Signs

  • Warning signs are yellow diamonds with black legends or symbols in rural and general use; they alert to conditions ahead.

  • A yellow diamond with a black arrow bent to the right or left warns of a curve ahead; a reverse curve sign shows an S-shape.

  • Winding road signs show a squiggly arrow and indicate a series of curves rather than a single curve.

  • Yellow diamond signs with a pedestrian, bicycle, deer, or farm equipment symbol warn of those hazards crossing or sharing the road.

  • A yellow diamond showing a downward slope warns of a steep hill; truck escape ramp or grade percentage may be posted separately.

  • Advisory speed plaques are yellow rectangles with black numbers mounted below warning signs; they are recommended, not the legal limit.

  • Chevron signs (black on yellow, one-direction arrow) mark the outside of sharp curves and guide drivers through the turn.

  • Two-way traffic and lane-ends signs warn that a passing or merging lane is ending; merge left or right as directed.

  • Fluorescent yellow-green is used for pedestrian, bicycle, and school warning signs to increase visibility.

Quick reference

Guide and Informational Signs

  • Guide signs give directions, distances, destinations, and services; they are informational rather than regulatory.

  • Green guide signs mark destinations, exits, and mileage on interstates and major highways.

  • Blue signs mark motorist services such as gas, food, lodging, camping, and hospitals.

  • Brown signs identify recreational, cultural, and historical points of interest.

  • White rectangular signs with black legends provide regulatory or informational messages such as speed limits and lane use.

  • Interstate route markers are red, white, and blue shields; U.S. route markers are white shields with black numbers.

  • Exit number signs appear above or beside exit direction signs and indicate the exit's milepost or sequential number.

  • Mile markers are small green signs with white numbers placed along the shoulder at one-mile intervals.

Quick reference

Construction and Work Zone Signs

  • Orange is the standard color for construction and maintenance warning signs, including workers, flaggers, and lane closures.

  • A diamond-shaped orange sign with a worker symbol warns of road work ahead; reduce speed and watch for equipment.

  • Flagger signs show a person holding a sign or flag and warn that traffic is being manually controlled.

  • Channelizing devices include cones, drums, barricades, and tubular markers; they define the travel path through a work zone.

  • A white rectangular sign with black legend reading 'FINES DOUBLE IN WORK ZONE' indicates increased penalties for violations.

  • Temporary rumble strips and portable changeable message signs are common work-zone traffic control devices.

  • Work zone speed limits are posted in advance of the work area; they remain in effect until an end-work-zone sign appears.

  • A flagger's STOP/SLOW paddle controls traffic; obey the paddle even when no other signal is present.

  • Detour signs are typically orange or black-on-white and direct traffic around a closed route.

Quick reference

School Zone and Pedestrian Signs

  • Fluorescent yellow-green pentagon signs mark school zones and school crossings.

  • A pentagon-shaped sign with a pedestrian symbol indicates a school crossing ahead.

  • School zone speed limits are posted on white regulatory signs and apply during posted hours or when children are present.

  • Crosswalk signs and in-street pedestrian crossing signs require drivers to yield to pedestrians in the crosswalk.

  • A pedestrian crossing sign (yellow diamond with walking figure) warns of a crosswalk ahead, not necessarily a school zone.

  • Stop for a school bus with flashing red lights and an extended stop arm; proceed only when the lights stop and arm retracts.

  • School bus stop-arm violations are enforced on both sides of a two-way road; divided highways may exempt opposing traffic.

  • Crossing guards use hand signals and stop paddles; drivers must obey their directions.

  • Watch for children walking or biking near schools during arrival and dismissal hours.

Quick reference

Railroad and Crossing Signs

  • A circular yellow sign with a black X and two R's marks a railroad crossing ahead.

  • A white X-shaped crossbuck sign with black letters marks the crossing itself; yield to trains.

  • Flashing red lights at a railroad crossing mean stop and remain stopped until the lights stop flashing and the gate is fully raised.

  • Never drive around a lowered gate or attempt to beat a train; trains cannot stop quickly.

  • Pavement markings before a railroad crossing include a large white X and the letters RR.

  • A sign reading '3 TRACKS' or similar under a crossbuck indicates multiple tracks; watch for a second train.

  • Some crossings have no gates or lights; stop, look, and listen before crossing.

  • A yellow diamond sign with a train symbol warns of a railroad crossing ahead where sight distance is limited.

Quick reference

Sign Colors and Shapes

  • Red means stop, yield, or prohibition; it appears on STOP, YIELD, DO NOT ENTER, and WRONG WAY signs.

  • Yellow warns of hazards ahead; most warning signs are yellow diamonds.

  • Orange marks construction and maintenance zones.

  • Green guides to destinations and distances on highways.

  • Blue indicates motorist services such as fuel, food, and lodging.

  • Brown identifies recreational and cultural areas.

  • White with black legend indicates regulatory requirements or information.

  • A red octagon is STOP; a red-and-white downward triangle is YIELD; a yellow diamond is a warning; a yellow pentagon is a school zone.

  • A white X-shaped crossbuck marks a railroad crossing; a circular yellow sign with an X warns of one ahead.

Pavement Markings and Signals

  • A solid yellow center line means no passing; a broken yellow line means passing is permitted when safe.

  • Two solid yellow lines mean no passing in either direction; a solid and broken yellow line permits passing only on the side with the broken line.

  • White lines separate lanes of traffic moving in the same direction; solid white means stay in lane, broken white means lane changes are allowed.

  • A solid white line at an intersection or edge marks the stop line or crosswalk boundary.

  • A red traffic signal means stop; a flashing red signal means stop, then proceed when clear.

  • A yellow traffic signal means the light is about to turn red; stop if it is safe to do so.

  • A flashing yellow signal means proceed with caution; a green arrow means protected movement in the arrow direction.

  • A steady green signal means proceed when clear; a green arrow gives the right-of-way for that movement.

  • Pavement arrows indicate required lane movements; a straight-arrow lane does not permit turning.
