The only information you should give to the insurance adjuster is your name, phone number, address, and date of birth. Do not give any other information even if they ask you. Politely decline to answer.
When they start asking you questions about the crash, the only information you should provide is the date and time of the accident and the make and model of any vehicles involved in the accident. Do not answer any other questions about the accident. Let the adjuster know your attorney will be contacting them to discuss any details.
