Flatbed Truck Insurance

Flatbed underwriting starts with the commodity list. Steel coils, structural steel, pipe, lumber, drywall, machinery and building materials each fail in their own way, so markets ask for each commodity's share of your loads and the highest value you carry on one trailer. A carrier hauling mostly lumber and roofing material is rated differently from one hauling coils and heavy machinery.

Equipment type comes next: flat, step deck, double drop, RGN or conestoga. Lowboys and RGNs suggest oversize and overweight permits, which means routing, escorts and bridge heights become part of the risk. Underwriters also ask how long each driver has run open deck specifically, because years in a dry van do not teach securement, tarping or how a load of pipe behaves in a hard stop.

Federal rules require cargo to be contained, immobilized or secured so it does not shift enough to affect the truck's stability or handling. For general cargo, the combined working load limit of the tiedowns must be at least one-half the weight of the article or group of articles. Chains, straps and binders all carry a rating, and the math is checked at roadside inspections.

Heavy machinery has its own rule. Wheeled or tracked equipment weighing 10,000 pounds or more must be restrained with at least four tiedowns, and accessory equipment such as a hydraulic shovel must be fully lowered and secured. Articulated machines must be blocked from articulating in transit. Drivers who haul equipment should know these by heart. Machines lighter than 10,000 pounds may be secured under this rule, the vehicle rule or the general cargo rules.

These rules matter to your insurance because a securement violation written up at the scene of a dropped load tells the adjuster and the other side's lawyer what happened. Keep a written securement procedure, train every new driver on it, and have drivers photograph the load before departure. Those photos settle cargo disputes that would otherwise turn on memory. They cost nothing to take.

Load shift under hard braking, loads that fall on a curve, and damage during crane or forklift unloading are frequent flatbed cargo losses. Lumber and drywall soaked through a torn tarp, and copper or steel stolen from a trailer parked at a truck stop, follow close behind. On the liability side, a dropped load or an oversize strike on an overpass can involve several vehicles at once.

Check how your cargo form treats loading and unloading. Some forms stop coverage when the freight leaves the deck, so a coil dropped by the receiver's forklift may be argued between policies. Also check for commodity exclusions; some forms exclude steel coils, glass or machinery unless they are listed. Your tarps, chains and binders are your property, not cargo, so they need their own equipment coverage.

List every commodity with a rough percentage and the highest value per load. Say how often you run oversize or overweight and in which states. Add driver open-deck experience, trailer types, three to five years of loss runs, and any securement training you require. Send pictures of a typical secured load; underwriters notice clean chains, edge protectors and squared tarps.

Match your cargo limit to your real loads, not to the lowest number a broker accepts. If one load of machinery is worth more than your cargo limit, the gap is yours. Ask for a written list of cargo exclusions before you bind, and compare it with what you actually haul. If you add a new customer with higher-value freight mid-term, call before the first load, not after.
