Who is Liable When a Commercial Semi-Truck Hydroplanes on Worn Tires During Heavy Rain?
Driving next to a massive commercial semi-truck during a severe rainstorm is always a terrifying experience. The massive tires kick up blinding walls of water, severely reducing visibility for everyone on the road. But the real danger isn't the spray—it's what happens when those 18 wheels lose their grip. When an 80,000-pound truck hits a patch of standing water at high speed and hydroplanes, it transforms into an unguided missile. The driver loses all steering and braking ability, resulting in catastrophic jackknifes, rollovers, and multi-lane pileups.
When police arrive at the scene of a wet-weather crash, trucking companies frequently blame the rain, trying to pass the crash off as an unavoidable "weather-related accident." However, heavy rain does not cause a truck to hydroplane—worn tires and excessive speed do. Determining who is liable when a commercial semi-truck hydroplanes on worn tires during heavy rain requires aggressively investigating the motor carrier's maintenance logs and the driver's decision-making in adverse conditions.
Hydroplaning occurs when water builds up in front of the tires faster than the weight of the vehicle can push it out of the way. The water pressure actually lifts the tire off the asphalt, causing the truck to ride on a thin layer of water. For a heavy semi-truck to hydroplane, two failures must occur: the tire tread must be too worn down to channel the water away, and the driver must be driving too fast for the grooves to do their job.
Proving Willful Negligence in a Hydroplaning Crash
A specialized plaintiff's attorney knows that a hydroplaning crash is almost never an "Act of God." It is the result of a trucking company trying to squeeze a few extra thousand miles out of a set of bald tires to save money. Liability is established through two major federal violations:
Federal law dictates extremely strict standards for commercial truck tires. The front "steer" tires must have a tread depth of at least 4/32 of an inch, while the rear drive and trailer tires must have at least 2/32 of an inch. When a truck crashes in the rain, an accident reconstructionist will immediately measure the remaining tread with a gauge. If the steer tires are completely bald, the motor carrier is strictly liable for negligent maintenance and putting an illegal, unroadworthy vehicle on the highway.
Even if the tires have legal tread, hydroplaning is a direct result of speeding. FMCSR Part 392.14 explicitly requires commercial drivers to significantly reduce their speed when hazardous conditions, such as heavy rain or standing water, exist. The CDL manual instructs drivers to reduce speed by at least one-third on wet roads. If the truck's Engine Control Module (ECM) data shows the driver was doing 65 mph in a torrential downpour right before losing control, they are guilty of reckless driving.
Drivers must inspect their tires daily. If the post-crash investigation reveals bald tires with exposed steel belts, but the driver's morning inspection report stated the tires were in "good condition," it proves the driver routinely lied on federal documents to keep moving freight.
Holding the Company Accountable for Greed
Commercial truck tires are expensive, costing up to $1,000 each. Unscrupulous companies will delay replacing them for as long as possible, hoping they can get away with it until the next DOT inspection. When this corporate greed results in a wet-weather catastrophe, victims are entitled to aggressive compensation.
