Can you turn or make a U-turn on double yellow dashed lines?

[VonChristopher]

Under safe conditions without obstructing traffic, left turns are permitted but U-turns are prohibited on double yellow lines on main roads. Here are the details: 1. Double yellow dashed lines: Left turns are allowed but U-turns are forbidden on main roads under safe conditions without hindering traffic. 2. Double solid yellow lines: U-turns, crossing, or high-speed turns are strictly prohibited. Violators will be fined and receive 3 penalty points. 3. One solid and one dashed yellow line: Vehicles on the dashed side can make U-turns or cross for turns when safe and without obstructing traffic, while vehicles on the solid side must not cross or linger on the double yellow lines.
