Get medical attention right away, call law enforcement, and document the scene if you can safely do so. Take photos, gather witness information, and avoid giving recorded statements to insurers before speaking with an attorney. Truck accident evidence can disappear quickly, including driver logs, black-box data, and maintenance records, so early legal involvement is important.
