Wide turn accidents occur when a semi-truck makes a right turn from a non-rightmost lane or swings wide left to complete a right turn, crushing other vehicles in the turn radius. These accidents frequently involve cyclists, motorcyclists, and small passenger vehicles that are invisible to the truck driver in the left mirror blind spot. FMCSA regulations require drivers to check mirrors before turns, and California Vehicle Code Section 21717 governs lane use for turns.
Commercial freight accidents in California involve a federal regulatory framework that creates liability theories unavailable in ordinary vehicle accident cases. FMCSA violations establish negligence per se. ELD and EDR data provide objective evidence of driver conduct. Commercial insurance minimums of $750,000 to $5,000,000 provide substantially higher coverage than personal auto policies. And multi-defendant litigation against the carrier, shipper, truck owner, and maintenance company is the norm rather than the exception.
In a wide turn / squeeze accident case, the motor carrier bears primary vicarious liability under respondeat superior and direct liability for FMCSA compliance failures. The truck driver bears personal liability for negligent driving. The truck owner (if different from the carrier) may be liable for the vehicle's mechanical condition. The cargo shipper may be liable if loading or securement contributed to the accident. The maintenance company may be liable if defective brake work or tire service contributed. Equipment manufacturers may be liable under Greenman v. Yuba Power Products strict products liability if a vehicle defect caused or contributed to the accident.
California's pure comparative fault system from Li v. Yellow Cab Co. (1975) allocates fault among all liable parties. Proposition 51 (Civil Code Section 1431.2) makes defendants jointly and severally liable for economic damages but liable only for their proportionate share of non-economic damages in multi-defendant cases.
The following FMCSA regulatory areas are most commonly implicated in wide turn / squeeze accident cases. A violation of any applicable standard that causally contributed to the accident establishes negligence per se — the violation satisfies the negligence element without further proof of unreasonable conduct.
General freight carriers: $750,000 minimum liability. Hazardous materials (listed substances): $5,000,000 minimum. Oil: $1,000,000 minimum. These minimums set the floor; most major carriers maintain policies substantially above these amounts plus umbrella coverage.
FMCSA-regulated carriers must maintain minimum liability insurance of $750,000 for general freight or $5,000,000 for hazardous materials. In serious wide turn / squeeze accident cases, the full insurance stack includes the carrier's primary commercial auto policy, umbrella or excess coverage, the truck owner's policy (if the truck is owned separately), and potentially the shipper's liability policy. All applicable policies must be identified and disclosed through the discovery process.
California freight accident civil claims recover: all past and future medical expenses (no cap); lost wages and lost earning capacity; property damage; non-economic damages (pain, suffering, emotional distress, disfigurement, loss of enjoyment of life) — uncapped; and punitive damages under Civil Code Section 3294 when the carrier acted with malice or conscious disregard of known safety violations. In catastrophic injury cases involving spinal cord injury, traumatic brain injury, or wrongful death, lifetime economic damages may reach several million dollars.
Two years from the date of the accident under CCP Section 335.1. Claims against government entities (Caltrans for highway defects, port authorities for port area defects) require a written administrative claim within six months under Government Code Section 945.4. Missing either deadline permanently bars that claim. Because ELD, EDR, and carrier communications are subject to automated deletion, a written preservation demand should be sent to the carrier and all other defendants as soon as possible after the accident.
The truck driver and motor carrier bear primary liability when a wide turn accident results from the driver's failure to check mirrors, improper lane positioning, or inadequate warning to other drivers. California Vehicle Code Section 21717 requires a driver to be in the right lane before turning right from that lane. Wide-turn accidents that result from improper lane entry violate CVC 21717 and establish negligence per se.
Yes. FMCSA 49 CFR Section 393.80 requires commercial motor vehicles to be equipped with rear-vision mirrors providing a full view of the highway for 200 feet behind the vehicle. In addition, drivers are required by FMCSA to check all mirrors before making turns or lane changes. Failure to check mirrors before a wide turn is a direct regulatory violation.
A semi-truck's right side has a significant blind spot extending from the front-right corner of the cab alongside the trailer. A vehicle positioned alongside the trailer — particularly motorcycles and cyclists — may be completely invisible to the driver in the right mirror. The length of the blind spot depends on the tractor-trailer configuration and mirror adjustment. An expert in commercial vehicle operations can testify to the specific blind spot dimensions for the truck involved in the accident.
Yes. A cyclist who was lawfully occupying the bike lane or right lane has the right of way and is not at fault for being in the position they occupied. The truck driver's failure to check the right mirror before initiating a right turn from a non-right lane is negligence per se under CVC Section 21717 and FMCSA mirror requirements. Cyclist injuries from wide-turn accidents are frequently catastrophic.
Key evidence includes: surveillance camera footage showing the truck's approach and turn; the truck's EDR data (speed and steering inputs); dashcam footage from the truck or other vehicles; the physical evidence of contact points on both vehicles; and witness testimony about whether the truck used a turn signal before initiating the turn.
Two years from the date of the accident under CCP Section 335.1. For government entity claims (e.g., if the road design contributed to the accident), six months under Government Code Section 945.4.
