Stick simply to the basics. Tell the adjuster where the accident happened, when it happened and who was involved. Do not admit fault. Do not give a recorded statement. Do not discuss your health prior to the accident.
Do not falsely believe “your” insurance company is on your side. Insurance adjusters are skilled at getting injured people to say things that harm their claim. That is why it is so important to stick just to the basics. If you are hurt, you can always defer other questions to your attorney.
