Tennessee Permit Practice Test

What does a double solid yellow line indicate?

1. No passing in either direction

2. Passing is allowed only during daylight

3. One lane can pass, but the other cannot

4. Only trucks are prohibited from passing

The correct answer is: No passing in either direction

A double solid yellow line indicates that no passing is allowed in either direction. This traffic marking is used to signify that the road is not safe for overtaking other vehicles due to potential hazards, such as curves, hills, or other situations where visibility is limited. The intent behind this marking is to enhance safety by preventing vehicles from attempting to pass one another, which could lead to dangerous situations or collisions. Other markings, like single solid lines or dashed lines, have different meanings regarding passing, suggesting that the rules may vary depending on road conditions and types. Understanding these distinctions is crucial for making safe driving decisions and adhering to traffic laws.
