Get medical attention first, even if symptoms seem manageable. Then preserve evidence: photos, witness names, police report details, delivery vehicle markings, and any information about the driver’s company. Avoid giving recorded statements to insurers before legal guidance. Marker Law can quickly request preservation of phone records, driver logs, black-box data, and maintenance records before key evidence is lost.
