Complete Colorado Permit Practice Test 2026

Dashed white lines between lanes moving in the same direction show that lane changes and passing are allowed when it’s safe. That’s why the statement you can cross or pass is correct. These markings help you move around slower traffic, unlike solid lines which indicate you must not cross. They also aren’t used to mark sidewalks or barriers. When you decide to pass, signal, check mirrors and blind spots, and ensure there’s enough room and visibility to complete the maneuver safely.
