No, normally tickets written to your friend while borrowing your car do not affect your rates. If instead the tickets were written against the vehicle then depending upon the violation it could affect your insurance premiums.

It is usually a good idea not to let those without a valid license drive your vehicle. If your friend was in an accident and your insurance policy has an exclusion for driver without a valid license then your insurance coverage would not have covered the accident. Or if they were covered your insurance could have been affected since you allowed an unlicensed driver to drive your car.
