Faulty products cause some car wrecks due to the negligence of the manufacturer, but negligent drivers are responsible for most accidents. Pennsylvania drivers must act reasonably toward other motorists, pedestrians, and bicyclists on the road with them. If a driver acts carelessly or recklessly, such as texting and driving or operating a vehicle while intoxicated, and an accident occurs, an injured party can file a lawsuit to help compensate for those injuries.
