32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Octagon sign shape
- The octagon is used only for STOP signs. Because no other sign shares this shape, a driver can identify a stop even when the legend is dirty, snow-covered, or viewed from behind.
- Downward triangle sign
- A downward-pointing triangle with a red border and white center marks a YIELD sign. The driver must slow, give right-of-way to crossing or merging traffic, and stop only if necessary.
- Yellow diamond meaning
- A yellow diamond warns of a condition ahead such as a curve, intersection, or grade. The sign does not state a legal requirement; it tells the driver to slow and be prepared.
- Orange sign meaning
- Orange backgrounds mark construction, maintenance, and temporary traffic control. Orange diamond signs warn of work zones, and orange rectangular signs give directions through or around the work area.
- Fluorescent yellow-green signs
- Fluorescent yellow-green is reserved for pedestrian, bicycle, and school warnings. Seeing this color tells a driver to expect people, especially children, near or in the roadway.
- Round yellow railroad sign
- A yellow circle with a black X and the letters RR is the railroad advance warning sign. It means tracks are ahead; slow down, look both ways, and listen before crossing.
- Crossbuck sign
- The crossbuck is a white X-shaped sign reading RAILROAD CROSSING, placed at the tracks. Drivers must yield to trains, and a number plaque below it states how many tracks remain.
- DO NOT ENTER sign
- A red square with a white horizontal bar and white legend marks a wrong-way entrance to a one-way road. Passing it puts you against traffic; turn around immediately.
- WRONG WAY sign
- A red rectangle with white legend reading WRONG WAY is posted on freeway ramps facing drivers who enter against traffic. It reinforces DO NOT ENTER and means you are traveling against the flow.
- Speed limit sign
- A white rectangle with black legend and numbers states the maximum lawful speed in ideal conditions. Exceeding it is a violation even if traffic appears to be moving faster.
- Advisory speed plaque
- A yellow plaque below a warning sign shows a recommended speed for a curve or ramp. It is advisory rather than a legal limit, but traveling faster is unsafe for the condition shown.
- One way sign
- A black rectangle with a white arrow indicates that traffic on that road moves only in the direction of the arrow. Entering against the arrow is a wrong-way violation.
- Steady red signal
- A steady red light requires a complete stop before the stop line or crosswalk. A right turn on red is allowed after stopping unless a sign prohibits it; left turns on red are limited to one-way streets.
- Flashing red signal
- A flashing red light functions as a STOP sign. Stop completely, yield to cross traffic, and proceed only when the intersection is clear.
- Steady yellow signal
- A steady yellow light warns that the signal is changing to red. Stop if you can do so safely; if stopping would be abrupt, proceed through and clear the intersection.
- Green arrow signal
- A green arrow indicates a protected movement in the direction of the arrow. Opposing traffic is stopped, so turning traffic on the arrow has the right-of-way.
- Double solid yellow line
- Two solid yellow lines separate opposing traffic and prohibit passing in both directions. Crossing them is allowed only for a left turn into a driveway or side road where legal.
- Broken yellow line
- A broken yellow line separates opposing traffic and permits passing when safe and legal. The broken line is on the side of the lane that may pass.
- Solid white line
- A solid white line separates lanes moving in the same direction and discourages lane changes. A broken white line in the same position permits lane changes when safe.
- Stop bar marking
- A thick solid white line across a lane marks where vehicles must stop at a signal or stop sign. Stop behind it so crosswalks and intersections remain clear.
- Green guide signs
- Green signs with white legend give destinations, distances, and exit information on highways and freeways. They are informational and do not impose a legal requirement on the driver.
- Blue service signs
- Blue signs identify motorist services such as gas, food, lodging, camping, and hospitals. They may show distance and direction to the service.
- Brown recreational signs
- Brown signs with white legend identify parks, recreation areas, historic sites, and cultural points of interest. They guide drivers to attractions rather than regulate traffic.
- Interstate route shield
- The interstate route marker is a shield-shaped sign with a red top band bearing the word INTERSTATE. The number below identifies the route, and even numbers run east-west.
- Flagger ahead sign
- An orange diamond showing a person holding a flag warns that a flagger is directing traffic ahead. Drivers must obey the flagger's signals, which may override the normal right-of-way.
- Type 3 barricade
- A type 3 barricade has three horizontal rails striped with alternating orange and white diagonals. It marks a road closure or serious hazard and must not be driven around.
- Detour sign
- An orange or black-on-white sign marked DETOUR directs traffic around a closed road or work area. Follow the marked route rather than driving through the closure.
- Work zone speed limit
- A posted speed limit in a work zone is regulatory and enforceable, often with doubled penalties when workers are present. It applies even though the sign is temporary.
- School zone sign
- A fluorescent yellow-green pentagon or diamond showing pedestrians or children warns of a school area. Reduce speed and watch for children and crossing guards.
- School speed limit sign
- A SCHOOL SPEED LIMIT sign with a time plaque or flashing beacon sets a lower limit during posted hours or when the beacon flashes. It is enforceable during those times.
- Railroad gate arm
- A lowered gate arm across your lane means stop and stay stopped until the gate rises completely. Never drive around a lowered gate; a second train may be approaching.
- Yield sign response
- At a YIELD sign, slow down and give the right-of-way to traffic on the intersecting road. Stop only if necessary to avoid interfering with that traffic.
