While driving, you encounter various signs, markings, and other vehicles. Some, like standard road lines, are familiar from driver's tests, but others are less common. A prime example is the yellow plastic flaps sometimes seen on the roadway.
These flaps, resembling plastic notes, are typically found in construction areas. They serve as temporary lane markers where permanent painted lines are absent, often on roads undergoing seal coat projects. According to California's transportation engineering guidelines, they are for short-term use, while other markers like raised dots are for longer repairs.
The article contrasts road conditions across the U.S., noting cities like Orlando and states like Rhode Island and California struggle with poor infrastructure. Conversely, states like Kansas and Wyoming, with less traffic, often maintain better roads.
