Updated September 21, 2026About these guides
Who writes these guides?
The Profirm compliance team. We have prepared carriers for FMCSA audits and filed their registrations since 1988. Each guide shows the date it was last reviewed, and we cite the regulation section so you can check the source.
Are the prices in the guides current?
Guides mention prices "at the time of writing". The current price list is on the pricing page, which is the source of truth; government fees are always shown separately.
Can I ask a question that is not covered?
Yes. Call us or use the contact page. If enough carriers ask the same question, it becomes the next guide.
