Get medical attention first, even if symptoms seem manageable. Report the crash, take photos if safe, collect witness information, and avoid giving recorded statements to trucking insurers before speaking with an attorney. Truck accident evidence such as driver logs, black-box data, and maintenance records can be time-sensitive, so contacting a lawyer quickly helps preserve proof.
