Introduction to No Passing Zones
Unlock Audio Lesson
Today, we are going to discuss no passing zones. Can anyone tell me what they think a no passing zone is?
Is it a area where you can't overtake another vehicle?
Exactly! No passing zones are areas marked on roads where overtaking is prohibited due to safety concerns. They usually occur where visibility is compromised.
What types of roads or situations have no passing zones?
Great question! They are commonly found on summit curves, horizontal curves, and two- or three-lane highways.
Marking of No Passing Zones

Now, how are these no passing zones marked?
Do they use yellow lines?
Correct! A solid yellow line indicates that passing is not allowed. If there are double yellow lines, the left side is usually solid and indicates strong restrictions.
What if there's a broken line on the other side?
If there’s a broken line on the right side of a solid line, it typically means the passing restriction applies only to the opposing traffic.
Importance of No Passing Zones
Unlock Audio Lesson
Why do we think no passing zones are important?
They help avoid accidents, especially in places where you can't see well.
Exactly! They are there to help ensure driver's safety by preventing overtaking in dangerous spots. Does anyone know why sight distance is important?
If you can't see ahead, you might not know if there's oncoming traffic!
Right! Marking no passing zones reduces the chances of head-on collisions.

Quick Overview
Standard
This section discusses no passing zones, which are marked areas on roads that prohibit overtaking due to low visibility conditions such as curves or summits. These zones are indicated by solid or double yellow lines, helping to ensure safety on highways.

No Passing Zones
No passing zones are critical traffic safety features established in areas where overtaking is prohibited. These zones are necessary due to adverse conditions like low sight distance, commonly found on summit curves and horizontal curves. The marking of no passing zones is typically done using solid yellow lines or double yellow lines. In the case of double yellow lines, the left side is usually a solid line (indicating stricter regulation), while the right side can either be a broken line or a solid line, depending on the specific traffic regulations in place. These solid lines are often referred to as barrier lines.
When a solid line is placed to the right of a broken line, overtaking is only restricted for the driver approaching the solid line from the opposing direction. The correct marking of no passing zones is essential for maintaining safe traffic flow and minimizing accidents.

No passing zones are established on summit curves, horizontal curves, and on two lane and three lane highways where overtaking maneuvers are prohibited because of low sight distance.
Detailed Explanation
No passing zones are specific areas on the road where drivers are not allowed to overtake other vehicles. These zones are typically marked in locations where visibility is poor, like at the top of a hill (summit curves) or on curves in the road (horizontal curves). The primary reason for establishing these zones is to enhance safety, ensuring that drivers do not attempt to pass other vehicles when they cannot see what is ahead.
Examples & Analogies
Imagine driving up a steep hill where you cannot see the road over the top. If there are cars coming down from the other side, trying to pass would be dangerous. This is why a no passing zone exists there; it helps prevent accidents by keeping everyone safe.
Visual Indications of No Passing Zones

It may be marked by a solid yellow line along the centre or a double yellow line. In the case of a double yellow line, the left hand element may be a solid barrier line, and the right hand may be a either a broken line or a solid line.
Detailed Explanation
No passing zones are visually indicated by road markings. A solid yellow line along the center means that passing is not allowed. In some cases, a double yellow line may be used, where one line may be solid (indicating no passing for that side) and the other may be broken (which could allow passing under certain conditions). This helps drivers understand the rules specific to that area of the road.
Examples & Analogies
Think of these lines like traffic signals. A solid line is like a red light: it means stop (or don't pass). The broken line on the other side is like a green light; it may allow passing but requires caution, just like checking for oncoming traffic before proceeding.
Barrier Lines

These solid lines are also called barrier lines. When a solid line is to the right of the broken line, the passing restriction shall apply only to the opposing traffic.
Detailed Explanation
Barrier lines are used to indicate which side of the road has restrictions on passing. When there is a solid line adjacent to a broken line on the left, it conveys that only the opposing traffic cannot pass. This distinction is crucial for maintaining order and safety on multi-directional roadways, especially in sections where visibility is limited.
Examples & Analogies
Picture a two-lane road with oncoming traffic. If the solid line is on your side, it’s like having a 'do not enter' sign for the other drivers. You can pass if you are in a broken line lane, but you must ensure there are no vehicles coming toward you, just like looking both ways before crossing a street.

Some typical examples are shown in figures 37:7 and 37:8.
Detailed Explanation
Figures referred to in the text illustrate specific examples of how no passing zones are marked on the roadway. These visual aids provide concrete examples of solid and double yellow lines, helping drivers understand how they should behave in these zones. Visual representations can clarify the rules more effectively than words alone by showing realistic scenarios.
Examples & Analogies
Think of these figures as safety manuals for drivers. Just like a map helps you find your way, these illustrations show you where it's safe to drive versus where you should exercise caution, making the ideas of no passing zones clearer and more digestible.
