No Passing Zone Sign
The no passing zone sign is a yellow pennant-shaped sign mounted on the left side of the road. It marks the beginning of a zone where passing other vehicles by crossing into the oncoming lane is prohibited. This sign is unique because it's the only US road sign with a pennant shape — a horizontal triangle pointing to the right. You'll see it on two-lane roads where visibility is limited, such as near hills, curves, or intersections. The sign works together with the solid yellow center line painted on the road. When you see this sign, it means conditions ahead make it too dangerous to pass — you can't see far enough to safely cross into the oncoming lane and return to your lane. The no passing zone ends when you see a dashed yellow center line return, indicating passing is allowed again when safe. Even where passing is technically allowed, you should only pass when you have clear visibility and enough distance to complete the maneuver safely.
Rules & What to Do
Do not cross the center line to pass another vehicle in a no passing zone. Wait until the dashed center line returns and you can see far enough ahead. Even outside no passing zones, only pass when it is legal and safe to do so.
Penalties
Passing in a no passing zone is a serious traffic violation. Fines typically range from $150-$400 and can carry 3-4 points on your driving record. Repeat offenses may result in license suspension.
For Commercial Drivers
For CDL holders, a passing violation is especially serious — it can count toward disqualification. Commercial vehicles need much more time and distance to complete a pass. Never attempt to pass in a no passing zone with a commercial vehicle. Remember that CDL holders face stricter penalties for moving violations.
