What does a solid double yellow line indicate about passing?

• A. Passing is allowed in both directions.
• B. Passing allowed for the driver on the left only.
• C. No passing for either direction.
• D. Passing is allowed during daylight hours.

Answer: (C)

Solid double yellow lines mean no passing in either direction. They show two-way traffic where crossing the lines to pass another vehicle isn’t allowed, so you stay in your lane and wait for a chance to pass only when there’s a dashed line or a designated passing zone ahead. The rule is about the road markings, not the time of day, so daylight or darkness doesn’t change the restriction. If you need to change lanes to turn left into a driveway or into another road, you may do so only when it’s safe and legal, but not to pass a slower vehicle.
