When you’re injured in a trucking accident case, it is paramount to hire a law firm immediately to protect your interest. The investigation begins almost instantly with the retaining of skid marks, the photographing of same, the downloading of the computer of the truck before the data are overwritten, and also an evaluation of any medical condition that the driver may have. Federal law requires that tests begin, the toxicology test, of drivers in certain circumstances. Your lawyer should insure that these things are looked into and accomplished.
