|---|---|---|
| Octagon | Stop | Make a complete stop and yield before proceeding. |
| Downward triangle | Yield | Slow down and give right-of-way; stop if necessary. |
| Diamond | Warning | Prepare for a hazard or road-condition change ahead. |
| Pennant | No-passing zone | Stay in your lane until passing is permitted again. |
| Round | Railroad advance warning | Slow down, look and listen, and prepare to stop. |
| Pentagon | School area or school crossing | Reduce speed and watch carefully for children. |
| Rectangle | Regulation, guidance, or service | Use the color and words or symbol to identify the instruction. |
Fast sign answers
Round, yellow, blue, and orange road signs
What does a round yellow sign indicate?
A round yellow sign with a black X and two Rs warns that a highway-rail grade crossing is ahead. Slow down, look and listen for a train, and be ready to stop. The white crossbuck is a different sign placed at the tracks.
What color are warning signs?
Most general warning signs use a yellow background with a black symbol or legend. Fluorescent yellow-green is used for certain pedestrian, bicycle, and school warnings, while orange marks temporary traffic-control and work-zone warnings.
What do blue road signs mean?
Blue signs usually identify motorist services such as hospitals, fuel, food, lodging, rest areas, telephones, accessible facilities, or traveler information. They guide rather than regulate traffic.
What do orange road signs mean?
Orange signs warn about temporary construction, maintenance, utility work, detours, lane changes, workers, or equipment. Slow down and follow flaggers and temporary traffic controls.

DMV road sign questions
What road signs should I study for the permit test?
Start with stop, yield, warning, speed limit, no passing, railroad, school, pedestrian, work-zone, guide, wrong-way, merge, slippery road, and divided-highway signs.
How many road sign questions are on the DMV test?
The number and format vary by state. Road signs are commonly tested as part of the written knowledge exam, so use this visual guide for recognition and your state driver handbook for the exact test format.
Is shape or color more important when identifying a sign?
Both matter. Shape can identify special signs such as stop, yield, railroad warning, no passing, and school-zone signs. Color helps separate warnings, regulations, work zones, guidance, and services. The final answer still depends on the symbol or words and the safe driver action.
What does a round yellow road sign mean?
A round yellow sign with a black X and two Rs warns that a railroad crossing is ahead. It is an advance warning sign, while the white crossbuck is installed at the crossing.
Do road sign meanings change by state?
Core MUTCD signs use nationally standardized designs and meanings, but state handbooks may emphasize different examples, local signs, pavement markings, or test wording. Confirm final study details with your state handbook.
Is this an official DMV sign manual?
No. US Permit Prep is independent and is not affiliated with a DMV or government agency. The images are based on official MUTCD standards, but your state handbook remains the final source for your exam.
Next steps
Turn sign recognition into test practice
Use the image-based test after reviewing the dictionary, or focus on one category when a group of signs still feels uncertain.
