A traffic accident lawyer is a man or a woman licensed by the state bar to practice law who specializes in traffic accidents. This covers a wide array of collisions including crashes between two vehicles, and a car hitting (and perhaps killing) a pedestrian, or an object. A traffic accident lawyer must be proficient in traffic and accident laws in his/her state, county, and municipality. For clients who have just been through an accident where they were not at fault, a traffic accident lawyer can negotiate a settlement on their behalf. Such a settlement should take into account all of the accident victim's post-accident financial needs (i.e., medical, job-related, etc.). Most traffic accident lawyers work pro bono; that is, they do not bill their client until the case has officially been resolved, usually through a financial settlement.
