Pennant signs warn you about no-passing zones

A pennant-shaped sign — narrow and pointed on the right side — tells you that you cannot pass other vehicles in that area. The sign is always yellow with black lettering or symbols, and it points in the direction of travel. You will see it on two-lane roads where passing is unsafe, usually because a curve or hill blocks your view of oncoming traffic.

The pennant appears on the left side of the road as you approach a no-passing zone. It marks the beginning of the zone, not the end. Once you see it, you must stay in your lane until you reach a solid white line or another sign that tells you passing is allowed again.

Unlike a stop sign or yield sign, the pennant does not require you to take an action — it straightforward restricts one. If you are already passing when you see it, you should complete the pass safely if possible, but you cannot start a new pass once you enter the zone.

Key Takeaways

  • Pennant signs are yellow with a pointed right edge and mark the start of a no-passing zone on two-lane roads.
  • The sign warns that oncoming traffic may be hidden by a curve, hill, or other obstruction, making passing dangerous.
  • You must not begin passing once you see a pennant sign, though completing a pass already in progress is usually permitted.
  • The no-passing zone ends when you see a solid white line change to a dashed line or another sign indicating passing is allowed.

Why pennant signs appear where they do

Road engineers place pennant signs in locations where the road geometry makes passing unsafe. A curve that tightens as you approach it, a hill that rises steeply, or a bridge with limited sight distance all trigger the need for a no-passing zone. The sign warns you before you reach the hazard, giving you time to adjust your speed and position.

The length of a no-passing zone varies. Some last only a few hundred feet; others extend for a mile or more. The zone is always long enough to cover the sight distance problem — if you cannot see far enough ahead to spot an oncoming vehicle and pass safely, you cannot pass.

How pennant signs differ from other warning signs

Most warning signs are diamond-shaped and alert you to hazards like curves, pedestrians, or slippery roads. A pennant sign is the only common warning sign with that narrow, pointed shape. The shape itself is a visual cue: the pointed end suggests a restriction or barrier, not just a warning.

Do not confuse a pennant sign with a no-passing line — the solid yellow line painted on the road itself. The sign appears first and warns you what is coming. The line reinforces the restriction and shows you exactly where it applies. Both work together to keep drivers from attempting unsafe passes.

What to do when you see a pennant sign

Slow down slightly and stay in your lane. Do not attempt to pass another vehicle. If a vehicle ahead of you is moving slowly, you will need to follow at a safe distance until the no-passing zone ends. Passing in a no-passing zone is illegal and puts you and oncoming drivers at serious risk.

If you are driving a truck, RV, or towing a trailer, the restriction applies to you the same way it applies to a car. Some states have additional rules for large vehicles, but the pennant sign means no passing for everyone.

When the no-passing zone ends

The zone ends when the solid yellow line on the road changes to a dashed yellow line, or when you see a sign indicating that passing is allowed again. At that point, you can pass if it is safe to do so. Do not assume the zone has ended just because the road straightens out — always look for the line change or a sign.

Some roads have multiple no-passing zones in a short distance. You may see another pennant sign shortly after the first zone ends. Stay alert and adjust your passing strategy accordingly.

Penalties for passing in a no-passing zone

Passing illegally in a no-passing zone is a traffic violation in all states. Fines range from around $100 to $500 or more, depending on your state and whether the violation caused an accident or endangered other drivers. The violation also typically adds points to your driving record, which can increase your insurance rates.

If your illegal pass causes a collision, you may face additional charges, including reckless driving or negligent driving. Insurance companies often deny coverage for accidents caused by traffic violations, leaving you responsible for all damages.

Frequently Asked Questions

Can I pass if I see a pennant sign but the road looks clear?

No. The pennant sign is placed because the road geometry — a curve or hill — will hide oncoming traffic from your view. What looks clear now may not be clear when you are halfway through the pass. The sign reflects engineering analysis of sight distance, not current conditions.

What if a slow driver is ahead of me in a no-passing zone?

You must follow at a safe distance until the zone ends. There is no exception for slow traffic. If the driver is going unusually slowly, you can flash your headlights or honk to encourage them to speed up, but you cannot pass.

Do pennant signs explore to motorcycles?

Yes. All vehicles, including motorcycles, must obey no-passing zones marked by pennant signs. Motorcycles are smaller and more maneuverable, but the restriction is the same.

Is it legal to pass if the oncoming lane appears empty?

No. Passing in a marked no-passing zone is illegal regardless of whether you see oncoming traffic. The zone exists because you cannot see far enough ahead to be certain the lane is clear. A vehicle can appear suddenly as you pass.

What if I am already passing when I see a pennant sign?

Most states allow you to complete a pass that is already underway when you enter a no-passing zone, as long as you do so safely and do not linger in the oncoming lane. However, you cannot start a new pass once you see the sign.
