Hundreds of people -- passengers, pedestrians and motorists -- are injured each year in mass transit accidents in the Baltimore area. Some people forfeit their right to compensation by waiting too long to bring a claim. Other victims never pursue legal action, believing that government entities are immune.
A public transit agency can be held liable -- the same as an individual or corporate entity -- but there are special rules and restrictions. Your best recourse is to work with a lawyer who has actually filed and won such claims.
