Final answer:
The lines that separate the shoulder from the travel lane are typically white or yellow and indicate the boundary between driving areas and emergency use areas like shoulders.
Step-by-step explanation:
Lines that separate the shoulder from the travel lane are typically white or yellow and are found on roads and highways to distinguish between areas where vehicles are meant to drive and areas meant for emergency or breakdown use. Specifically, on a freeway, you will often find a solid white line that demarcates the shoulder from the travel lanes, ensuring that drivers recognize the boundary and do not inadvertently drive in the shoulder area unless necessary. For a rabbit attempting to cross the lanes of the freeway, whether or not it can do so safely depends on a variety of factors including traffic patterns, the presence of vehicles, and the rabbit's speed, but these lines serve to guide human drivers rather than wildlife.
