The first 90 days
Most of what affects a claim happens before anyone speaks to a lawyer.
Do
See a doctor even if you feel able to carry on; concussion and soft-tissue symptoms routinely appear days later. Report the collision to your own insurer within 30 days. Keep every receipt: prescriptions, parking, mileage to appointments, equipment. Attend treatment consistently, and tell your practitioner what you can't do, not just where it hurts. Write down what changed: sleep, concentration, lifting, driving, work you've had to hand off.
Be careful with
Recorded statements to the other driver's insurer: you are under no obligation to give one, though your own insurer is different because you have a contractual duty to cooperate with them. Early settlement offers, frequently made before treatment is finished, when nobody yet knows the extent of recovery. Social media: photos and posts are routinely used to argue an injury is less limiting than described. Stopping treatment early because you're improving but not recovered.
