: Anything drawn with a broken line is considered "environmental" or non-material.

On the pavement, broken lines translate into freedom and caution. They are the primary tool for regulating traffic flow without creating rigid physical barriers.

: Ironically, using more broken lines can make a patent stronger. By using broken lines for most of an object and solid lines only for a specific unique feature (like the horn of a saddle), the patent owner prevents competitors from copying that one part, regardless of what the rest of the product looks like.

: A combination of a solid and broken line creates a "one-way" permission; only the driver on the side of the broken line may legally cross to pass.
