Can You Sue USPS for a Car Accident? Yes — Here's How

If you've searched "can you sue the post office" after a collision with a mail truck, you've probably found conflicting answers — some flatly saying no, others hedging without explaining why. The honest, specific answer is: yes, you can sue the federal government over a USPS vehicle accident, and the confusion comes from a real legal rule that simply doesn't apply to your situation.

The Real Rule People Are Half-Remembering

Congress waived the federal government's sovereign immunity broadly through the Federal Tort Claims Act — but carved out specific exceptions where it didn't want federal courts second-guessing agency operations. One of those exceptions, 28 U.S.C. § 2680(b), bars "any claim arising out of the loss, miscarriage, or negligent transmission of letters or postal matter."

That exception exists so that the courts aren't flooded with lawsuits over every delayed letter, lost package, or misdelivered piece of mail. It says nothing about vehicles, driving, or traffic collisions — it's about the mail itself, not the truck carrying it.

A Truck Crash Isn't a Mail-Loss Claim

Courts have consistently read § 2680(b) as limited to claims about the handling of the mail — not general negligence by postal employees that happens to occur during mail operations. A USPS driver running a red light, following too closely, or making an unsafe turn is ordinary negligence, evaluated the same way any car accident is evaluated, just through the FTCA's administrative process instead of a direct lawsuit.

What Actually Can Block a USPS Accident Claim

The myth aside, a few things genuinely can bar or complicate a claim:

• Missing the two-year SF-95 deadline — see the full deadline rules →
• The vehicle was driven by an independent contractor, not a USPS employee — see how to tell the difference →
• The driver was acting outside the scope of their postal duties at the time (a fact-specific dispute, not a blanket rule)
• The claim genuinely is about lost or damaged mail, not a vehicle collision

None of these describe an ordinary "a mail truck hit my car" scenario. If that's your situation, you have a claim.
