Determining liability in a bus accident case involves thoroughly investigating the specific circumstances surrounding the accident. In many cases, the bus company can be held liable for the injuries of the bus passengers, especially if negligence or a breach of duty on the part of the company or its employees contributed to the accident. However, liability can also be shared with other parties, such as negligent drivers, maintenance companies. It is advisable to consult with a bus accident lawyer who can evaluate the details of your case and provide accurate legal advice based on the specific circumstances.
