When are you allowed to cross a solid double line?

Crossing a solid double line is permitted in specific situations, and one of those scenarios is making a left turn into a driveway. The primary purpose of solid double lines is to prevent unsafe lane changes and maintain traffic flow, particularly on busy roadways. However, when you are making a left turn into a driveway, crossing this line is justified as it allows for safe access to private properties.

For clarity, while it is essential to check that traffic is clear and that the maneuver is safe, the fundamental rule is that solid double lines restrict lane changes but allow for controlled turns into side streets or driveways. This helps manage traffic safety while also enabling drivers to access residences or businesses located along the road.
