Montana Permit Practice Test

The presence of thick broken white lines on your left typically indicates that you are in an exit lane. These lines serve as a guide for drivers, marking where an exit begins and helping to delineate the path that vehicles should take to safely exit the roadway. In this context, the thick broken lines are designed to alert you to the change in traffic patterns and to assist you in maneuvering out of through lanes onto an exit ramp. In contrast, bicycle lanes are often marked with solid and thin lines, and they are intended specifically for cyclists. High-occupancy vehicle (HOV) lanes are usually marked with symbols and signs indicating their specific use, and merging lanes typically have different line configurations that reflect the merging process rather than just exit guidance. Hence, the characteristics of the thick broken white lines support the identification of the lane as an exit lane.
