32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- STOP sign shape
- A red octagon with a white legend reading STOP. It is the only sign with this shape, so it is recognizable from the back and in poor visibility.
- YIELD sign shape
- An inverted red-and-white triangle. Drivers slow down and stop only if necessary, giving right-of-way to cross traffic and pedestrians before proceeding.
- DO NOT ENTER sign
- A red square or rectangle with a white horizontal bar and the words DO NOT ENTER. It marks a one-way road or ramp that traffic may not enter from this direction.
- Speed limit sign meaning
- A white rectangle with black numerals and the words SPEED LIMIT sets the maximum legal speed under normal conditions. Drivers must slow when weather or traffic makes that speed unsafe.
- Warning sign color and shape
- Warning signs are yellow diamonds with black legends and symbols. They alert drivers to conditions ahead and do not by themselves change speed limits or right-of-way rules.
- Advisory speed plate
- A yellow or white rectangular plate mounted below a warning sign, such as a curve sign, showing a recommended maximum speed for the hazard ahead under good conditions.
- School zone sign
- A five-sided fluorescent yellow-green pentagon showing walking children. The posted school speed limit applies during stated hours or when children are present near the school.
- Slippery when wet sign
- A yellow diamond warning sign showing a car with skid marks. It warns that the road surface loses traction when wet, so drivers should reduce speed and avoid sudden braking.
- Steep grade warning
- A yellow diamond showing a slope with a percentage, such as 6%. Drivers should slow down and shift to a lower gear before descending to prevent brake fade.
- Interstate route marker
- A red, white, and blue shield with the word INTERSTATE and a number. Even numbers generally run east-west and odd numbers generally run north-south.
- Blue service signs
- Blue signs with white symbols identify services such as gas, food, lodging, hospital, and telephone available at or near an upcoming exit.
- Brown guide signs
- Brown signs with white legends identify parks, historic sites, and recreational areas. They are informational and do not indicate fuel, food, or lodging services.
- Exit number with letter
- An exit number followed by a letter, such as Exit 15A, indicates a split exit with separate ramps. Each lettered ramp leads to a different destination or direction.
- Mile marker purpose
- A small green sign with white numbers placed along the shoulder. It gives the driver's location for emergency calls and helps estimate distance to destinations.
- Orange sign meaning
- Orange signs mark temporary traffic control in construction and work zones. Orange diamonds warn of conditions, and orange rectangles give directions or detours.
- Flagger paddle signals
- A flagger uses a paddle with STOP on one side and SLOW on the other. Drivers must obey the flagger's signals and stop completely when directed.
- Channelizing devices
- Cones, drums, and barricades that mark the path through a work zone. Drivers must stay within the marked path and must not cross the devices.
- Work zone speed limit
- A posted temporary speed limit in a work zone, often white with an orange border. It is enforceable when displayed, even if no workers are visible at that moment.
- Detour sign
- An orange sign with black arrows and route markers that directs traffic around a closed road. Drivers follow it until the route rejoins the original road.
- Red sign color meaning
- Red on a sign means stop, yield, or prohibition. It appears on STOP, YIELD, DO NOT ENTER, and WRONG WAY signs and on prohibition symbols.
- Yellow-green pedestrian signs
- Fluorescent yellow-green marks pedestrian, bicycle, and school warning signs. The color is more visible than standard yellow in low light and bad weather.
- Prohibition symbol
- A red circle with a diagonal slash through a black symbol means the action shown is prohibited, such as no left turn or no bicycles.
- Railroad advance warning sign
- A round yellow sign with a black X and the letters RR warns of a railroad crossing ahead. Drivers should slow down, look, and listen before crossing.
- Crossbuck sign
- A white X-shaped sign marked RAILROAD CROSSING at the tracks. It has the same effect as a yield sign, so drivers must yield to approaching trains.
- School bus red lights
- Flashing red lights and an extended stop arm on a school bus require traffic to stop. On an undivided road, traffic in both directions must stop.
- Railroad gate and lights
- Flashing red lights at a crossing mean stop. A lowered gate means remain stopped until the gate is fully raised and the lights have stopped flashing.
- Solid yellow line
- A solid yellow line separates opposing traffic and prohibits passing. A double solid yellow line prohibits passing for traffic in both directions.
- Broken white line
- A broken white line separates lanes moving in the same direction and permits lane changes when safe. A solid white line discourages or prohibits lane changes.
- Stop line marking
- A solid white bar across a lane at an intersection. Drivers stop before it at a STOP sign or red light, or before the crosswalk if no line exists.
- Flashing red signal
- A flashing red traffic signal is treated like a STOP sign. Drivers come to a complete stop, yield to cross traffic and pedestrians, then proceed when clear.
- Green arrow signal
- A green arrow means a protected turn in the arrow's direction. Oncoming traffic is stopped, so the turn may be made without yielding to opposing vehicles.
- Steady yellow signal
- A steady yellow signal warns that the light is changing to red. Drivers should stop if they can do so safely rather than accelerate through the intersection.
