If a mail truck driver caused your accident while on the job, you generally can’t file a claim with an insurance company the way you would after a typical car accident case. Federal law usually requires you to file a claim against the United States Postal Service itself, through a process called the Federal Tort Claims Act, and that process runs on its own rules and deadlines.
Missing one of those deadlines can end a valid claim before it starts. A San Luis Obispo truck accident attorney at Ernst Law Group can help you get the paperwork right the first time.
Who is responsible when a mail truck causes an accident?
It depends on whether the driver worked for USPS directly or worked for a company USPS hired, and that distinction changes how you recover. If a USPS employee, like a career letter carrier, ran a red light or rear-ended you while delivering mail, the government stands in the driver’s place, and your claim moves through the Federal Tort Claims Act.
A lot of mail trucks aren’t driven by USPS employees at all, though. USPS contracts out large portions of its delivery and trucking routes to private companies, and just this January, USPS announced it’s tightening background checks on those contracted drivers after safety concerns. When a contractor’s negligence causes the crash, the Supreme Court has held that the federal government generally isn’t liable for it, unless USPS controlled the day-to-day details of how the contractor did the job, not just the contract terms. In that situation, your claim usually looks like an ordinary truck accident case against that company and its insurance company, not against the federal government. USPS can still end up liable on its own account, separately, if its own negligence in vetting or supervising that contractor played a role in the crash.
What is the Federal Tort Claims Act?
A collision with a government vehicle, like a mail truck, doesn’t work like most car accidents involving a private driver. The Federal Tort Claims Act (FTCA) is the federal law that lets you sue the government for a federal employee’s negligence, and it’s why a mail truck accident doesn’t work like an ordinary motor vehicle accident claim. Without it, sovereign immunity would block a lawsuit against the United States entirely.
Instead, the FTCA, codified at 28 U.S.C. Chapter 171, lets the government be sued much like a private employer would be for an employee’s negligence, but only after you follow its specific claims process first.
How do you file an injury claim against the USPS?
You start by filing Standard Form 95 with USPS, the government agency responsible for mail delivery, not a lawsuit. That form asks for:
- The federal agency involved
- Your contact information
- The details of the accident, including any evidence you can provide
- The dollar amount of your losses
- Any witness information
You have two years from the date of the accident to file that form. That’s a federal deadline built into the FTCA itself, not California’s ordinary two-year injury deadline, and it applies the same way no matter what state you’re in.
What happens after you file your FTCA claim?
USPS has up to six months to respond, and what happens next depends on what they say. They may approve your claim and offer an amount. They may deny it, and a denial can be appealed administratively or taken straight to a truck accident lawsuit. Or they may not respond at all, in which case federal law treats that silence as a denial once six months have passed, and you can move forward with a lawsuit at that point.
If USPS sends you an actual written denial, don’t sit on it: you then have only six months from that notice to file a lawsuit in federal court, not two years. For a San Luis Obispo accident, that lawsuit would go to the U.S. District Court for the Central District of California, which covers San Luis Obispo County.
What compensation can you recover in a mail truck accident case?
You can generally recover the same categories of damages as any other car accident case: medical expenses, lost wages, property damage, and pain and suffering. Two things work differently here, though. Punitive damages aren’t available against the federal government no matter how careless the driver was, and if you hire a lawyer, federal law caps what they can charge you: 20% of an administrative settlement, or 25% if your case goes to a lawsuit, both lower than a typical contingency fee.
Suing the federal government is hard; Ernst Law Group knows how
