What Is a Brake Failure / Runaway Truck Accident?

Brake failure on a commercial truck can result in runaway truck incidents — most commonly on steep mountain grades where brake fade from overheating renders the vehicle uncontrollable. Runaway trucks frequently reach speeds above 80 mph before impact, resulting in some of the most catastrophic crashes in NHTSA databases.

Common Causes

→Brake fade from riding brakes down a long grade
→Brake drum overheating due to improper adjustment
→Brake system air pressure loss (air brake failure)
→Deferred maintenance on brake components (FMCSA violation)
→Brake fade in a heavily loaded vehicle over driver weight limits
→Brake chamber pushrod out-of-adjustment

Common Injuries

→Catastrophic multi-vehicle crash injuries
→Traumatic brain injury and spinal cord injury
→Multiple fractures and internal injuries
→Burns and crush injuries
→Wrongful death

Key Evidence & Liability Factors

▸Brake inspection and adjustment records
▸DVIR records showing known brake deficiencies
▸Roadside inspection results (CVSA out-of-service criteria)
▸Carrier's CSA BASIC score for Vehicle Maintenance
▸ECM data showing speed on the grade and brake application history

FMCSA note: FMCSA 49 CFR § 393.40–393.55 governs brake performance standards for commercial vehicles. Out-of-adjustment brakes are the single most common CVSA roadside violation. Evidence that the carrier had prior brake violation notices and failed to correct them is highly damaging.

Oklahoma Fault Laws and How They Affect Your Settlement

Oklahoma uses the 50% bar rule. This is governed by Oklahoma Statutes, Title 23, § 13 (modified comparative fault, 51% bar).

Oklahoma Fault Rule: Modified Comparative Fault (50% Bar)

Under Okla. Stat. tit. 23, § 13, if you are assigned 49% or less of the fault, your damages are reduced proportionally. If you are assigned 50% or more, you recover nothing.

Example: Your damages are $600,000 and you are 30% at fault. Recovery: $600,000 × 0.70 = $420,000.

Major Oklahoma freight corridors: I-40, I-35, I-44, US-69, US-75 — these interstates carry the highest commercial truck traffic volume in the state and account for a disproportionate share of large truck crashes.
