Yes, Louisiana has a following distance rule made just for trucks. On the open highway, one truck has to stay at least 400 feet behind another truck it is following. Most drivers in Baton Rouge have never heard of this rule, and it does not work quite the way most people assume.
What the 400-Foot Rule Actually Says
Louisiana Revised Statute 32:81 holds this rule. Outside a business or residential area, a truck cannot follow another truck within 400 feet. That is more than the length of a football field. The rule does not apply when one truck is passing another, and it does not apply once trucks are back in town, near businesses or homes. Lawmakers built in this extra room because trucks take longer to stop, block sight lines, and turn a small mistake into a much bigger crash.
Does the 400-Foot Rule Protect Cars From Trucks Too?
This is where many drivers get it wrong. The 400-foot number is specific to one truck following another truck. It does not set a special distance for a truck following your car, or your car following a truck. Instead, every driver, in every kind of vehicle, still has to follow the same general rule found in the same statute. Louisiana law says no one can follow another vehicle more closely than is reasonable and prudent, based on speed, traffic, and road conditions. So while there is no separate 400-foot number protecting your car, the law still requires the truck behind you to leave a safe gap. It simply measures that gap in judgment rather than in feet.
Why Louisiana Lawmakers Singled Out Trucks
Following too closely is already one of the most common things drivers do wrong. The AAA Foundation for Traffic Safety found that 50.8 percent of drivers admit to tailgating another vehicle on purpose within the past year, more than admit to honking in anger or yelling at another driver. The Governors Highway Safety Association lists following too closely among the core forms of aggressive driving, right alongside speeding. Add a loaded truck to that picture and the stakes rise fast. A truck weighs many times more than a car and needs much more room to stop. That is exactly why Louisiana gave trucks their own numeric rule instead of leaving it to judgment alone.
What This Looks Like on Baton Rouge and Ascension Parish Roads
Anyone who drives I-10 through the industrial corridor, Airline Highway, or Highway 30 toward Gonzales knows how much truck traffic moves through our area every day. Plants, ports, and warehouses across East Baton Rouge Parish, St. George Parish, and Ascension Parish keep a steady stream of trucks on these roads, often bunched together in traffic. The Insurance Institute for Highway Safety reported 752 crash deaths in Louisiana in 2024, a rate of 16.4 per 100,000 people, with 41 percent involving more than one vehicle. Technology is starting to help. IIHS research shows vehicles with forward collision warning and automatic braking are involved in about half as many rear-end crashes, and forward collision warning alone cuts them by about 27 percent. Still, no dashboard warning replaces a driver, truck or car, giving the vehicle ahead enough room.
What To Do If You Are Hit While Near a Truck
If you are ever rear-ended by a truck, or caught in a chain reaction crash involving one, your safety comes first. Move somewhere safe if you can, check on everyone with you, and call 911. Get a copy of the police report, take pictures of every vehicle involved, and get checked by a doctor even if you feel fine, since some injuries from a heavy vehicle crash do not show up right away. I have sat with families in my office after crashes like this, and the ones who gathered this information early always had an easier path toward the care and compensation they needed. Louisiana’s fault rules can get complicated fast when a commercial truck is involved, since a trucking company, its insurer, and sometimes a cargo company may all share responsibility.
Quick Answers About Louisiana’s Truck Following Law
Does the 400-foot rule apply to a truck following my car?
No. The specific 400-foot distance only applies to one truck following another truck outside a business or residential area. A truck following your car still has to follow the same reasonable and prudent standard every driver must follow.
Is a truck automatically at fault if it rear-ends me?
Often, yes, since the law expects a following driver to leave enough room to stop. But truck crashes can involve more than one responsible party, so it helps to talk with an attorney before accepting an early settlement offer.
What should I do if a truck is riding too close behind me?
If you can do it safely, move over and let the truck pass rather than speeding up or braking hard. Keep an eye on your mirrors and give yourself an exit if traffic allows.
