Broker Swapped Your Carrier Without Telling You: Your Rights

You verified the carrier, checked their FMCSA record, confirmed the insurance — and then a different carrier shows up at pickup, or the broker calls to say your original carrier "fell through" and they've assigned someone new. Here's what your rights are and what to check before your car goes anywhere.

Why carriers get swapped

Carrier substitution happens for legitimate and illegitimate reasons. Legitimate reasons include mechanical breakdown, driver illness, route changes, or the original carrier losing their operating authority. Illegitimate reasons include the broker re-brokering your load to a cheaper carrier to increase their margin, or the broker never having a confirmed carrier in the first place.

Regardless of the reason, any carrier substitution must be handled correctly or it exposes you to significant risk — including receiving your vehicle from an uninsured carrier with no recourse.

What brokers are legally required to do

Under FMCSA regulations, licensed brokers must only dispatch shipments to licensed, insured carriers. This obligation applies equally to the original carrier and any substitute. When a broker swaps your carrier, they are required to:

• Use a carrier with valid FMCSA operating authority (active MC number)
• Ensure the substitute carrier carries adequate cargo insurance (minimum $75,000 for auto transport)
• Provide you with the substitute carrier's information before or at the time of pickup

Brokers who substitute a carrier and don't disclose it — or who use carriers without verifying their credentials — are violating FMCSA regulations.

The double-brokering risk

The worst-case scenario in carrier substitution is double-brokering — your broker re-assigns your load to another broker, who then assigns it to a carrier. This creates a chain where no one in the middle is the carrier of record, insurance coverage becomes unclear, and when damage occurs, everyone points at someone else.

Signs your load may have been double-brokered:

• The arriving carrier has a different name than anything your broker mentioned
• The driver can't tell you who their dispatcher is or references a company name you've never heard
• The paperwork the driver presents shows a different broker name than yours
• Your broker can't tell you the name of the carrier or their MC number on request

What to do when a carrier shows up that you didn't authorize

• Do not hand over your vehicle immediately. You have the right to verify the carrier before your car is loaded.
• Ask the driver for their MC number and company name. Look up the MC number on the FMCSA SAFER system (safer.fmcsa.dot.gov) from your phone. Confirm their authority is active and their insurance is current.
• Call your broker and demand confirmation that this is the carrier they authorized and that the substitute carrier meets their insurance requirements.
• Get the substitution in writing — a text or email from your broker confirming the new carrier name and MC number before the car is loaded.
• If you cannot verify the carrier's credentials, refuse the pickup. An unverified carrier taking your car is the highest-risk position you can be in.

Your right to refuse

You are not obligated to release your vehicle to a carrier you did not agree to use and cannot verify. If the broker substituted a carrier without your knowledge or consent and the substitute cannot provide valid credentials, refusing the pickup is a legitimate exercise of your contractual and consumer rights.

Document the refusal in writing to your broker immediately: "I refused pickup by [carrier name] on [date] because I was not notified of the substitution and was unable to verify their FMCSA credentials. Please confirm authorized carrier information before rescheduling."

After the fact: if the car was already picked up

If you only discovered the substitution after pickup, document everything you can: the actual carrier's truck number, DOT number (on the cab door), driver's name, and any paperwork they gave you. Run the DOT number through FMCSA SAFER. If the carrier doesn't have valid authority or insurance, contact your broker in writing immediately and file an FMCSA complaint documenting the unauthorized substitution.
