Frequently asked questions
About trucking companies in Phoenix, AZ
Which trucking company in Phoenix has the biggest fleet?

How many motor carriers operate out of Phoenix?
1,747 active carriers list a Phoenix, AZ headquarters address in the FMCSA census (after filtering for realistic fleet data). The top 100 by fleet size are ranked on this page; the rest are searchable by USDOT or MC number.
What does the ranking on this page measure?
Position reflects self-reported power units — tractors, straight trucks, and buses, excluding trailers — from each carrier's MCS-150. A plausibility filter (driver-to-truck ratio between 0.3 and 5.0) removes registrations with obviously bad data before ranking.
What shows up on each carrier's linked profile?
Every row links to that carrier's public record page: red and caution risk flags with point deductions, a category-by-category score breakdown, the month-over-month FMCSA record timeline, insurance filing history, and any shared-contact links to other carriers — all from federal data, refreshed on a rolling ~48-hour cycle.
Do I need an account to vet a Phoenix carrier?
No — the public record pages are open. A free account adds the deeper workup: BASIC percentile detail, crash-by-crash records, live insurance verification against federal minimums, and watchlist monitoring with change alerts.
