The survivors of a woman killed in an ambulance crash on Nov. 30 have filed a wrongful death lawsuit, naming both the ambulance company and the driver.

The woman, 36, was being transported in the ambulance to the hospital on Interstate 40 at Charlotte Pike, Tennessee.

The West Tennessee evening was rainy, and the driver told police that the wet road caused the ambulance to hydroplane. It subsequently hit a rock wall, and the patient and a 36-year-old paramedic tending to her in the back of the ambulance were ejected.

Both patient and paramedic were taken to the hospital, where they died.

According to EMS1.com, a preliminary investigation showed that the weather and excessive speed led to the crash.

The lawsuit was filed by the father of one of the woman’s two children on behalf of both of them. A jury trial has been requested.

Additionally, police said the crash remains under investigation; criminal charges have not been filed.

According to the lawsuit, the “proximate cause of (the woman’s) injuries, damages, suffering, and death, was the negligence of (the driver), who was negligent by failing to maintain a proper lookout; by failing to maintain proper control of her vehicle; by driving too fast for the road conditions; by failing to make use of the proper visual and audible emergency signals; by disregarding her duty to use due care for the safety of all persons; and by recklessly disregarding the safety of others.”

The family of the paramedic who was killed in the accident also could seek legal representation and file a wrongful death lawsuit of their own. He is survived by his wife and two children, one of whom has special needs. He was an Army veteran and the recipient of a purple heart.
