Final answer:
The question deals with the interpretation of road signs related to the transition from a one-way to a two-way highway and the role of signage in traffic safety. It also touches on tollbooth mechanisms for detecting approaching vehicles.
Step-by-step explanation:
The question pertains to road signs and traffic safety, focusing on the transition from a one-way highway to a two-way highway and the importance of signage in that context. Road signs are crucial for providing drivers with information and warnings about the road ahead. Proper interpretation ensures safety not only for the driver but also for pedestrians and other vehicles. A sign indicating the end of a one-way road and the beginning of a two-way road alerts drivers to adjust their driving accordingly.
Tollbooths often have a mechanism, such as a wire trigger, to detect vehicles approaching to facilitate the toll process. This is an example of how infrastructure is designed to manage traffic flow and safety. Understanding road signs and their importance can significantly decrease the frequency of accidents and enhance overall roadway safety.
