An insured driver is unknowingly driving an uninsured car and has an accident The owner of the uninsured car is injured Who pays for the uninsured owners injuries?

this is tricky, dependant on the state laws...you are driving an uninsured vehicle, you have insurance on another vehicle of your own, you get into an accident that is your fault...the owner of the vehicle is a passenger in the car and is injured...your policy should step in and cover this uninsured vehicle (assuming you have collision coverage on your policy) you chose to drive, (doesn't matter you didn't know it was uninsured) and if your neglience resulted in this passengers injuries your policy will likely pay for their injury subject to any exclusion in the policy.....sorry.....
