Cases involving individuals who have been injured in crashes and collisions involving commercial airlines, railroads, oceangoing vessels, and government-operated municipal bus and rail systems. Some of the most common mass transit accidents are caused by sudden starts and stops, speeding, intoxication of operators and slippery floors. Buses are often involved in accidents with other motor vehicles, pedestrians, and bicyclists. Trains sometimes come derailed or have toxic spills that affect many people. People who are injured in mass transit accidents may be compensated for their injury, lost income, and pain and suffering.
