Carriers shown are active for-hire carriers with their registered address in Iowa, at least 5 power units in both months, and no passenger carriers. Counts come from each company's FMCSA (MCS-150) filings, so they are only as current as its last filing, and a large change can be a correction or a merger rather than growth. They do not show hiring or layoffs. See the methodology. More views: fastest by percent growth, fastest driver growth, and the national ranking.
