AAA Driver's Ed Permit Practice Test

Solid double yellow lines indicate no passing in either direction. They mark a restriction where overtaking is not allowed, often because visibility is poor or the road conditions make passing dangerous. You may cross these lines only to enter or leave a driveway or private road, or to complete a left turn across the lines when it’s legal and safe. Otherwise, stay in your lane and do not attempt to pass. Unlike lines with a broken mark that may allow passing when safe, a solid double line prohibits it.
