When you find both a solid and a dashed yellow line, when are you allowed to pass?

Answer: B — When the dashed line is on your side

When you encounter both a solid and a dashed yellow line, the passing rules hinge on the side of the dashed line. If the dashed line is on your side, it indicates that you are permitted to pass when it is safe to do so. The dashed line signifies a passing zone, meaning drivers can overtake other vehicles if the roadway ahead is clear. In contrast, if the solid line is on your side, it signifies that passing is prohibited; this usually indicates a more dangerous situation, such as limited visibility or potential traffic hazards, which could make overtaking another vehicle unsafe. Additionally, while the presence of oncoming vehicles is always a consideration for safety, the key rule here is specifically tied to the position of the dashed line relative to your vehicle.
