Truck Wreck Cases

Speeding Truck Accident Lawyer in Louisville, Kentucky

Federal rules bar carriers from schedules that require speeding. Here is how speed is proven after a truck crash and who can be responsible.

Reviewed by Larry Forman, Attorney.

A loaded tractor-trailer can weigh up to 80,000 pounds. Speed makes it harder to stop, harder to steer around a slowdown, and far more destructive on impact. Speeding is one of the most common things investigators find in serious truck crashes, and it is one of the easiest to prove when the evidence is preserved in time.

Speed rules that apply to truck drivers

  • Posted limits: Kentucky’s default limit is 65 mph on interstates and parkways, and the Transportation Cabinet can raise some rural interstate segments to 70 (KRS 189.390).
  • Too fast for conditions: every driver must go no faster than is “reasonable and prudent” for traffic and road conditions (KRS 189.390(2)). A truck doing the limit in rain, fog, a work zone or stopped traffic can still be speeding.
  • Federal rule on schedules: a motor carrier can’t schedule a run, or allow a driver to operate, in a way that requires the truck to go faster than the speed limit to make the delivery (49 CFR 392.6).

No federal rule currently requires speed limiters on heavy trucks, but many carriers set them anyway. When a company’s own trucks are governed and this one wasn’t, or the setting was raised, that is evidence.

How we prove speed in a speeding truck accident

  • Engine control module (“black box”) data: speed, braking and throttle in the seconds before impact. See truck black box evidence.
  • Telematics and GPS: many fleets track speed in real time and flag speeding events.
  • Logs and dispatch records: a delivery window that could only be met by speeding points to the company, not just the driver.
  • Camera video: the truck’s own cameras, nearby businesses and TRIMARC traffic cameras. See TRIMARC camera footage.
  • Reconstruction: crush damage, skid marks and final positions. See accident reconstruction.
  • The driver’s history: prior speeding tickets and company warnings in the driver qualification file, and the carrier’s public safety record. See FMCSA safety records.

Who can be responsible

The driver, and in most cases the trucking company, which is responsible for its driver’s conduct on the job and for its own decisions about schedules, pay structure and supervision. A company that pays by the mile, sets impossible delivery windows or ignores speeding alerts can be liable for its own negligence. See trucking company liability. Extreme speed can support punitive damages in Kentucky when the conduct shows gross negligence (KRS 411.184).

Insurance, fault and deadlines

Interstate carriers hauling general freight must carry at least $750,000 in liability coverage (49 CFR 387.9). Kentucky’s pure comparative fault rule means your recovery is reduced only by your own share of fault, if any (KRS 411.182). Most motor vehicle injury lawsuits must be filed within two years after the injury or the last PIP payment, whichever is later (KRS 304.39-230(6)).

Speeding truck accident FAQs

How do you prove a semi-truck was speeding?

Usually with the truck’s engine control module data, fleet GPS and telematics, camera video and reconstruction. Records like these can be overwritten, so a preservation letter should go out quickly.

Can the trucking company be liable if the driver was speeding?

Yes. The company is generally responsible for its driver’s conduct on the job, and it can be liable for its own negligence, such as scheduling runs that require speeding, which federal rules prohibit (49 CFR 392.6).

Are trucks required to have speed limiters?

There is no federal speed limiter requirement in effect for heavy trucks. Many carriers set governors on their own; whether this truck had one, and how it was set, can be evidence.

Can a truck be speeding even below the speed limit?

Yes. Kentucky requires every driver to go no faster than is reasonable for traffic and road conditions (KRS 189.390(2)). A truck at the limit in heavy rain or stopped traffic can be going too fast.
