Saskatchewan SGI Driving Practice Test

A double solid yellow line indicates that no passing is allowed in either direction. This marking serves as a clear visual cue to drivers that overtaking other vehicles is prohibited due to safety reasons, typically in areas where visibility is limited or where the road conditions are deemed hazardous. The purpose of this rule is to prevent accidents by discouraging dangerous maneuvers that could lead to head-on collisions, making it crucial for drivers to adhere strictly to the no-passing zone indicated by the double solid lines. In contrast, passing is permitted in scenarios marked by a single solid line or dashed lines, which would allow for more flexibility in lane usage. However, the presence of double solid lines unequivocally signals the need for caution and compliance with the no-passing rule, ensuring safety on the roads for all users.
