Tennessee Permit Practice Test

What does a solid yellow line indicate?

1. Passing is permitted

2. No passing allowed

3. Lane changes are allowed

4. Yield to oncoming traffic

The correct answer is: No passing allowed

A solid yellow line is a critical marking on the roadway that indicates no passing is allowed. This means that vehicles are not permitted to cross over the line to pass another vehicle in the same lane. The presence of a solid yellow line typically signifies that the road conditions or visibility are not favorable for safely executing a pass, which could lead to dangerous situations if attempted. Drivers are thus instructed to stay in their lane when a solid yellow line is present, ensuring safety for both themselves and other road users. In contrast, the other choices do not accurately reflect the meaning of a solid yellow line. For instance, passing would be permitted with a different marking, typically a broken yellow line, and lane changes are also not authorized when a solid line is present. Yielding to oncoming traffic pertains more to specific signage or situations rather than lane markings.
