- Stop sign shape
- An octagon with a red background and white letters. It requires a complete stop at the stop line, crosswalk, or before entering the intersection, followed by yielding to traffic and pedestrians.
- Yield sign shape
- A downward-pointing triangle with a red border and white center. Slow down, give the right-of-way, and stop only if necessary to avoid a collision with cross traffic.
- No U-turn sign
- A white rectangular sign with a red circle and slash over a black U-turn arrow. It prohibits making a U-turn at that location, often because of limited sight distance or median design.

- A red square with a white horizontal bar and the words DO NOT ENTER. It marks the wrong way into a one-way road or ramp; you must not proceed past it.
- Advisory speed plaque
- A yellow rectangular plaque below a curve or ramp warning sign showing a recommended speed. It is not a legal limit but indicates a speed safe for the curve in good conditions.
- Merge sign
- A yellow diamond or rectangular warning sign showing two lanes joining. It warns that your lane or an adjacent lane ends, so adjust speed and position and yield as required.
- Slippery when wet
- A yellow diamond sign with a car and skid marks. It warns that the pavement loses traction when wet; reduce speed before the hazard and avoid sudden braking or steering.
- Low clearance sign
- A yellow or white sign showing a height in feet and inches. Vehicles taller than the posted clearance must not pass under the bridge or overpass.

- Brown recreation signs
- Brown rectangular signs with white legends mark parks, historic sites, recreation areas, and scenic points of interest, often with directional arrows and distances.

- A hand-held sign, usually red with STOP on one side and SLOW on the other. The flagger's direction has the force of a traffic signal; obey it exactly.
