In 2017, Sales opposed legislation to require motorists to maintain a distance of 3 feet from bicyclists at 35 mph or less, and 5 feet at faster speeds. In debate, Sales harshly attacked cyclists, calling them "some of the most self-centered, rude people navigating on the highways and county roads I’ve seen" and saying that there were "too many of them" in Montana. Sales' remarks prompted Derek Bouchard-Hall, the president and CEO of USA Cycling, to write an open letter to Sales expressing disappointment.
