Road Signs: Regulatory, Warning, and Guide
What this domain tests
The Road Signs domain checks whether you can identify a sign by shape and color, state its meaning, and choose the correct driving action. Louisiana uses the national sign system, so the same shapes and colors appear on OMV test items.
Core rules
- Regulatory signs control actions: STOP (red octagon), YIELD (red-and-white inverted triangle), SPEED LIMIT (white rectangle with black legend), DO NOT ENTER (red square with a white bar), and WRONG WAY (red rectangle). These are enforceable; a warning sign is not.
- Warning signs are usually yellow diamonds with black symbols: curve, intersection, pedestrian, deer, slippery when wet. They tell you to slow or prepare, not that a law is being commanded.
- Guide signs are green for destinations and exits, blue for services, and brown for recreation. Orange is reserved for construction and maintenance.
- Special shapes matter: the school zone sign is a pentagon, the railroad crossing has a crossbuck, and the no-passing sign is a pennant.
Worked example
A yellow diamond shows a pedestrian walking. The shape and color identify a warning, not a regulatory crosswalk law. The correct response is to reduce speed, scan both sides, and be ready to stop for a pedestrian. If the same symbol appeared on a white rectangular sign, it would be regulatory and enforceable.
Traps
Do not treat orange work-zone signs as permanent warnings; speeds and lanes can change. Do not confuse the YIELD triangle with a stop sign-yield means slow and give way, stopping only if needed. A pennant means no passing zone, not school zone.
Quick recall
When a sign is yellow, think warning and prepare to slow. When it is white with black letters, think enforceable rule. When it is green, think navigation.
