If you have ever driven near a loaded log truck on I-10, you know the feeling. Your hands grip the wheel a little tighter. Here is the direct answer. Louisiana law caps the speed of the heaviest log trucks at 55 miles per hour, even on the interstate. A fully loaded log truck can weigh up to 92,000 pounds, more than six times an average car. A truck that heavy cannot stop the way your car can, no matter how skilled the driver is.
What Louisiana Law Says About Log Truck Speed
Louisiana gives log trucks a special rule most other trucks do not get. Under Louisiana Revised Statute 32:387, trucks hauling raw farm and forest products, like pulpwood, wood chips, and timber, can carry more weight than a normal truck, up to 86,600 pounds on state highways and 83,400 pounds on interstates like I-10.
Some log trucks buy a timber harvest season permit for $100 a year to carry even more weight, up to 92,000 pounds. That permit comes with a trade-off. It caps the truck’s speed at 55 miles per hour, no matter what the posted speed limit says.
This tells us something important. Louisiana lawmakers already know an extra heavy log truck moving fast is dangerous. The 55 mph cap is the state saying, in plain terms, that speed and weight do not mix on a log truck.
Two Baton Rouge Area Crashes That Show Why This Rule Matters
This is not just a rule sitting on a page. Two fatal log truck crashes near Baton Rouge, less than two weeks apart, showed exactly why it exists.
On April 16, 2026, a 22-year-old Rosedale man named Collin Smith was killed when his Buick Enclave crossed the center line on LA Highway 77 near Grosse Tete in Iberville Parish and struck a loaded log truck head-on. Both vehicles caught fire. The truck driver was hurt but survived.
Less than two weeks later, on April 28, 2026, a passenger van collided with an 18-wheeler hauling logs in Zachary. A 50-year-old man named Earnest Matthews died in that crash.
Two fatal log truck crashes in the greater Baton Rouge area within a month is not a coincidence. Grosse Tete and Zachary both sit along the timber corridor that feeds mills near I-10, and log trucks travel these roads every day.

Why a Loaded Log Truck Cannot Stop Like a Car
The Insurance Institute for Highway Safety reports that 5,340 people died in large truck crashes nationwide in 2024. Most of them, 62 percent, were riding in the other vehicle, not the truck. Newer NHTSA data, cited by the Truck Safety Coalition, shows this is not a one-year spike, with 5,000 to 6,000 deaths a year in recent years, up 58 percent since 2009, and more than 160,000 injuries every year. In fatal truck-car crashes, 96 percent of the deaths are car occupants, not truck occupants.
The reason is simple physics. A loaded truck takes much longer to stop than a car, and that gap grows worse on wet roads. Drivers behind the wheel more than eight hours are twice as likely to crash, and a truck with a serious brake problem is up to three times more likely to be in a deadly one. Speed only makes an already heavy, hard to stop truck more dangerous.
Do Log Trucks Get a Break on Driving Hours?
Some readers ask if log trucks get the same hours of service break as farm trucks. They do not. Federal law lets farm haulers skip standard driving hour limits close to where they picked up their load, but that exception is written narrowly for agricultural commodities and does not cover logs or timber. Log truck drivers on I-10 follow the same federal rules as most truckers, an 11 hour driving limit and a 14 hour on duty window, which matters because fatigue is one of the biggest risk factors in large truck crashes.
Louisiana’s Own Numbers Tell the Same Story
Louisiana is not immune. In 2024, 752 people died in motor vehicle crashes statewide, a rate higher than most of the country, and large truck occupants made up 22 of those deaths. TEAM Safe Trucking, a nonprofit that trains log truck drivers, lists speed management and space management as core skills alongside fatigue awareness, because the people who haul logs for a living know how much is at stake.

What I Have Learned Sitting With Families in My Office
I have sat across the desk in my office from many families after a truck crash changed their lives in one afternoon. Before I started Chris Corzo Injury Attorneys, I spent 13 years at GMIA, and I am proud to be recognized as a National Top 100 Trial Lawyer. I graduated from LSU Law and built my career right here in Baton Rouge, because this is my home.
A log truck crash is rarely simple. You have to look at the driver’s logbook, the weight of the load, the permit on file, and whether the truck was going faster than the law allows. That takes real investigation, and no family should have to do it alone while grieving or healing.
That is why Dignity Prevails is more than a saying at our firm. It means moving fast when a family needs answers, fighting for real recovery, and treating every person who walks through our door with the care they deserve.

Frequently Asked Questions
Is there really a lower speed limit for log trucks in Louisiana?
Yes. Log trucks carrying extra weight under a timber harvest season permit are capped at 55 mph under Louisiana Revised Statute 32:387, even on interstates like I-10.
Do log truck drivers get a farming exception for driving hours?
No. The federal agricultural commodity exception applies to farm haulers, not log or timber haulers. Log truck drivers follow the standard 11 hour driving limit and 14 hour on duty window.
What should I do if a log truck hits my car?
Get to safety, call 911, and get medical care even if you feel fine. Take photos if you are able, and try to get the trucking company’s name off the truck. Then talk to a lawyer before you speak with the trucking company’s insurance adjuster.
Who can be held responsible for a log truck accident?
It depends on the facts. Responsibility can fall on the truck driver, the hauling company, or a mill that set an unsafe delivery schedule. An investigation into speed, weight, and permits often points to the real cause.
