What does a solid double yellow line indicate?

• A. No passing in either direction.
• B. Passing allowed in one direction.
• C. Passing allowed with caution.
• D. Always pass on the left.

Answer: (A)

Two solid yellow lines side by side mark a two-way road and show that passing is not allowed in either direction. They’re placed where visibility or conditions make overtaking unsafe, so you should stay in your lane and wait for a dashed line ahead (a designated passing zone) before you consider passing. You may cross the lines to make a left turn into a driveway or private road when it’s safe and legal, but you should not use them to pass another vehicle.
