    • Obtained a jury verdict for the defense in a traumatic brain injury case with a settlement demand of $7.4 million at the time of trial. The twenty-one year-old plaintiff was the front seat passenger in his friend's car when they struck the rear of a tractor trailer owned and operated by the trucking company defendant. At the time of this accident, Pennsylvania still followed the doctrine of pure joint and several liability between joint tortfeasors. Accordingly, plaintiff could recover all of his damages from the defendant if its driver was found to be at least one percent responsible for causing the accident. Plaintiff's counsel retained trucking industry and human factors experts to testify in support of the negligence claims against the truck driver; however, the majority of plaintiff's witness at trial testified concerning plaintiff's alleged injuries and damages. The jury deliberated for under one hour before returning a verdict in favor of the defendant and finding the truck driver was not negligent. (Battestelli v. Werner Enterprises, Inc., et al.)
    • Obtained a jury verdict for the defense in a catastrophic personal injury case with a settlement demand of $4.5 million. The driver plaintiff alleged that a defect in the braking system of a John Deere 300C articulated dump truck owned and leased by Mr. Dumont's client reportedly caused the plaintiff to lose control of the vehicle and sustain a traumatic brain injury, comminuted tibia and fibula fractures requiring surgical intervention, rib fractures, herniated cervical and lumbar discs as well as other injuries and damages. (Simon v. Abele Tractor & Equipment, et al.)
    • Obtained a jury verdict for the defense in a fatal vehicular accident case. Plaintiff claimed a turning tractor trailer blocked the decedent’s lane of travel and caused decedent's vehicle to under-ride the trailer; blood tests showed the decedent had a blood alcohol level of 0.245%, or 3 times above the legal limit, at the time of the accident. (Estate of Warner v. J.B. Hunt transport Inc.)
    • Obtained a defense verdict in favor of an insurer at a bench trial. Following a motor vehicle accident involving the plaintiff corporation's vehicle, the plaintiff filed a declaratory judgment action to obtain an order declaring that it was entitled to a defense and indemnity under the insurer's commercial auto policy. The insurer denied coverage and contended that the policy had been cancelled prior to the accident due to non-payment of the  premium. (Mortuary Removal Services, Inc. v. Lancer Insurance Company, et al.)
    • Secured a jury verdict for the defense in a $250,000 personal injury case. Plaintiff had been involved in an intersectional collision and sustained a herniated lumbar disc and aggravation of pre-existing avascular necrosis requiring surgery on both hips. (Orlando v. A&R Transport, Inc.)
    • Obtained a jury verdict for the defense in an accident case with a settlement demand of $500,000. The case involved a left turn collision where 26 year-old driver plaintiff sustained brachial plexus traction injury and underwent two surgical procedures. (Wysocki v. Apache Transport)
    • Obtained a jury verdict for the defense in a case involving a plaintiff with multiple sclerosis, cervical laminectomy, and depressive disorder. (Vitaioli v. J. B. Hunt Transport)
    • Obtained a jury verdict for the defense in a case alleging that a turning tractor trailer blocked the plaintiff's lane of travel and caused a collision in which the plaintiff sustained a right ankle injury requiring open reduction and fixation surgeries, and ultimately fusion surgery. Blood test showed that the plaintiff's blood alcohol level was 0.15% as the time of the accident. (Archer v. Ward Trucking Company)
    • Obtained a jury verdict for the defense in a disputed lane change accident. The 18 year-old plaintiff sustained multiple fractures to the pelvis requiring a metal plate and eight screws, fractured ribs, a lacerated spleen, lacerated kidney, a right clavicle fracture, and a puncture wound to her left thigh resulting in a 10" scar. (Vargo v. Werner Enterprises, Inc.)
    • Secured a substantially lower settlement agreement on behalf of trucking client Swift Transportation Co. in a personal injury case. The plaintiff was a truck driver who stopped to assist a Swift driver and was allegedly injured when the truck moved while he was under the trailer helping to install a pin at the rear tandem. The defense was hampered by the fact that the court had to rely on the plaintiff's version of the accident because Swift's driver was no longer an employee and could not be located. The plaintiff's initial demand was $750,000, later lowered to $350,000 prior to trial. At trial, the jury found the plaintiff 25% negligent and awarded $75,000. (David v. Swift Transportation Co.)
