32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Stop sign shape
- An octagon with a white legend on a red background. It is the only octagonal sign, and a full stop is required at the stop line, crosswalk, or intersection edge.
- Yield sign shape
- An inverted triangle with a red border and white center. Slow down and stop only if needed to let cross traffic or pedestrians pass before proceeding.
- Do Not Enter sign
- A red square with a white horizontal bar and white text. It marks the wrong direction of travel, often at one-way street exits or freeway off-ramps.
- Speed limit sign
- A white rectangle with black legend stating the maximum lawful speed under favorable conditions. Exceeding it is a violation even if conditions seem safe to you.
- Warning sign color and shape
- Yellow diamond with black legend or symbols. It is placed in advance of a hazard, and an advisory speed plaque below it gives a recommended safe speed.
- Advisory speed plaque
- A yellow rectangular plaque with black numerals placed below a warning sign. It states a recommended maximum speed for the hazard, not a legally posted limit.
- Winding road sign
- A yellow diamond showing a series of reverse curves. It warns that the road ahead alternates direction, so reduce speed before entering the first curve.
- Two-way traffic sign
- A yellow diamond showing opposing arrows. It warns that a divided highway is ending or that oncoming traffic will share the roadway ahead.
- Green guide sign
- A green sign with white legend used on freeways and expressways. It shows destinations, route numbers, distances, and exit directions for navigation.
- Blue service sign
- A blue sign with white symbols identifying motorist services such as gas, food, lodging, hospitals, and rest areas ahead. It is informational, not regulatory.
- Brown recreation sign
- A brown sign with white legend marking parks, historic sites, and cultural or recreational areas. It guides travelers to points of interest rather than controlling traffic.
- Interstate route shield
- A red, white, and blue shield marking an Interstate highway. U.S. routes use a black-and-white shield, and state route markers vary by state.
- Orange work zone sign
- An orange diamond or rectangle with black legend warning of construction, maintenance, or a flagger ahead. Orange is reserved for temporary traffic control areas.
- Flagger authority
- A flagger directing traffic in a work zone has the same authority as a traffic signal. Obey the flagger's stop and slow signals over posted signs.
- Detour sign
- A sign, often orange or black on white, with an arrow directing traffic around a closed route. Follow the posted detour until the normal route reopens.
- Work zone speed limit
- A posted reduced speed limit in a construction area. It is enforceable when posted, and fines are commonly doubled when workers are present.
- Yellow center line
- Yellow lines separate traffic moving in opposite directions. A solid yellow line on your side means no passing; a broken line permits passing when safe.
- White lane line
- White lines separate traffic moving in the same direction. Dashed lines permit lane changes; solid white lines discourage or prohibit crossing.
- Edge line colors
- A solid white edge line marks the right edge of the roadway. A solid yellow edge line marks the left edge of divided highways and one-way roads.
- HOV lane marking
- A diamond symbol painted in the lane, paired with signs, marks a high-occupancy vehicle lane. Only eligible vehicles may use it during posted hours.
- Steady red signal
- Stop before the stop line or crosswalk. A right turn on red is allowed after a full stop unless a sign prohibits it, and you must yield to traffic.
- Flashing red signal
- Treat a flashing red light as a stop sign. Come to a complete stop, yield to conflicting traffic, and proceed only when the way is clear.
- Flashing yellow signal
- Slow down and proceed with caution. A flashing yellow does not require a stop, but you must yield to vehicles and pedestrians with the right of way.
- Green arrow signal
- A green arrow gives a protected turn, meaning conflicting traffic is stopped. A red arrow prohibits the movement, and a yellow arrow warns the phase is ending.
- School zone sign
- A fluorescent yellow-green pentagon or diamond marking a school area. The reduced school speed limit applies when beacons flash or during posted hours.
- Crossing guard signal
- A crossing guard's stop paddle and hand signals carry the authority of a traffic control device. Stop when directed and remain stopped until released.
- Bicycle lane marking
- A solid white line with a bicycle symbol marks a lane reserved for cyclists. Motor vehicles may not drive in it except when crossing to turn or park.
- Pedestrian right of way
- Drivers must yield to pedestrians in marked or unmarked crosswalks. Stop and remain stopped until the pedestrian has cleared your path.
- Railroad advance warning
- A round yellow sign with a black X and RR letters warns that a railroad crossing is ahead. Slow down and prepare to stop if signals activate.
- Crossbuck sign
- A white X-shaped sign with black RR letters marking the crossing itself. It has the force of a yield sign, so yield to any approaching train.
- Flashing red crossing lights
- Red lights flashing at a railroad crossing mean stop. Do not proceed until the lights stop flashing and you have confirmed no train is approaching.
- Shape meaning summary
- Octagon means stop, inverted triangle means yield, diamond means warning, pentagon means school, round means railroad advance, and crossbuck marks a railroad crossing.
