Do Not Pass Sign
The do not pass sign is a white rectangular regulatory sign with the words "DO NOT PASS" in black text. It is posted on the right side of two-lane roads to indicate that passing other vehicles by crossing into the oncoming lane is prohibited. While the pennant-shaped no passing zone sign is posted on the left side of the road, the do not pass sign is posted on the right side — both convey the same message but from different positions for maximum visibility. The do not pass sign works together with solid yellow center line markings. You'll see this sign in areas where passing would be dangerous due to limited sight distance, hills, curves, intersections, or other hazards. The restriction ends when you see a "PASS WITH CARE" sign or when the solid yellow center line changes to a dashed line on your side. It's important to understand that even where passing is allowed, it's only legal if you can clearly see far enough ahead to pass safely and return to your lane without interfering with oncoming traffic. The general rule is you need at least 10-12 seconds of clear visibility to pass safely.
Rules & What to Do
Do not cross the center line to pass another vehicle where this sign is posted. Wait for the restriction to end, indicated by a dashed yellow center line on your side. Only pass when it is both legal and safe to do so.
Penalties
Passing where prohibited is a serious moving violation with fines typically ranging from $150-$400 and 3-4 points. If the illegal pass causes an accident, penalties escalate significantly, including potential criminal charges for reckless driving.
For Commercial Drivers
CDL drivers should almost never pass on two-lane roads. The time and distance required for a commercial vehicle to pass is much greater than for a car, making it extremely dangerous. If you must pass, you need significantly more clear distance. An illegal passing violation counts as a serious traffic violation for CDL holders and can contribute to disqualification.
