When you find both a solid and a dashed yellow line between opposing lanes of traffic, you must not pass:

When you encounter a solid and a dashed yellow line between opposing lanes of traffic, the rules regarding passing become quite clear. A solid yellow line indicates that passing is not allowed for the lane adjacent to that line. Therefore, if the solid line is on your side, you are prohibited from changing lanes or attempting to pass another vehicle. This rule is in place to ensure safety, as passing when you're not permitted can lead to head-on collisions or dangerous situations, especially if there is oncoming traffic.

The dashed line, on the other hand, allows vehicles on the side of the line where it appears to pass safely. However, you must adhere to the regulations regarding the solid line, which takes precedence. This is why recognizing which type of line is adjacent to your lane is crucial for safe driving and following traffic laws.
