Even if you sustain only minor injuries when your car is hit by a truck, you should take photographs of the vehicles involved in the accident, submit a report to your insurance company, and seek medical attention immediately. You need to document your physical injuries by getting an evaluation from a medical professional. If possible, submit a report to the DMV. Make sure police reports are filed. Do not talk to the claims adjuster of the trucking company. Seek legal advice if planning to claim compensation.
