signals-markings
A double solid yellow centerline divides a two-way road. May you pass a vehicle by crossing it?
- Yes, if the vehicle ahead is below the speed limit
- Yes, but only during daylight
- No, passing is prohibited in either direction
- Only motorcycles may cross it
Answer: No, passing is prohibited in either direction. Double solid yellow centerlines mark the middle of a two-way road where passing is not allowed in either direction. The speed of the vehicle ahead does not create an exception, and daylight does not change the marking. Motorcycles do not receive a special permission to cross it for a pass. Keep your vehicle on its side of the roadway and wait for a legal passing opportunity. A useful distinction is that a dashed yellow line can permit a safe pass, while the paired solid lines remove that option for traffic moving both ways.
