This is a series of 5-8 railroad rails spaced 3 to 6 inches apart so that cattle won't try to cross. In Montana, the bicycle is recognized as a legal vehicle on the roadways, so you as the cyclist are subject to all of the same traffic laws you would obey as a motorist. But, there are also rules of the road dictated by common courtesy. Show courtesy to motorists and pedestrians as well as fellow cyclists. If you'd like to take a look at specific cycling laws for the state , you'll find them at this link.
Time of day is often an important safety consideration.
Temperatures are usually best, and traffic is lightest, in the early morning hours. Avoid leaving or approaching major population centers during rush hours or at the noon hour. If you can, be off the road before 5 p.m. Low or glaring light conditions, heavy traffic, fatigue of both driver and bicyclists, and the appearance of the drinking driver make this the most dangerous time of day. Night riding is not recommended. When on the highway, leave the roadway when you hear a car approaching.
