This is a very good question.
The answer depends on many things, and I'm not trying to give you lawyer talk.
Generally speaking if you were injured due to another's negligence or carelessness, you will have a valid claim.
Other factors are important, too, such as whether the responsible party—called the tortfeasor—carries liability insurance or has the financial ability to pay your damages.
It should not take a good lawyer very long to determine if you have a good case, and if it is worth pursuing or not. Surely every once in a while the circumstances can be complex and need to be investigated before a decision is made.
The bottom line is to call for a free consultation. I always appreciate getting a call from a potential client, even if a claim is ultimately not pursued. Knowledge is power. Make an intelligent decision. Don't leave your situation to chance. If the lawyer you call does not seem interested, see another.
