What is indicated by a double solid line?

A double solid line indicates that passing is not permitted at any time. This road marking serves as a clear visual warning to drivers that they must not cross the lines for the purpose of overtaking another vehicle. The use of double solid lines is particularly important in areas where visibility is limited, where there might be increased risks due to road conditions, or where traffic patterns warrant additional caution.

It emphasizes the need for safety and traffic regulation, reinforcing that remaining in your lane is crucial to prevent accidents. Drivers should respect these markings to ensure their safety and the safety of others on the road. The other choices suggest various allowances for lane changes and passing, which contradict the intended message of a double solid line.
