While driving in the far right lane of a four-lane freeway, what do thick broken white lines on the left side of your lane indicate?

Thick broken white lines on the left side of your lane indicate that you are driving in an exit lane. These lines are designed to provide a clear visual cue to drivers that they are approaching an area where they can exit the freeway. The thick broken lines signal that the roadway is transitioning, and drivers should be prepared to either change their direction or exit the freeway. This is particularly important for maintaining safe and efficient traffic flow, allowing drivers to maneuver safely without causing confusion or sudden stops. Understanding road markings is crucial for safe navigation, especially in multi-lane environments like freeways.
