There is no way to tell other then verifying his coverage after an accident.
Yes.
P.S. The insured driver is found at-fault with witnesses. The uninsured driver is worried if his license will be suspended or facing any penalty for driving the his parent's INSURED car.
No direct answer, as this all depends of the level of cover of the insured driver.
Call 911 and let the police sort it out.
As far as states go I know in Utah it is the vehicle not the driver that is insured.
Only if the truck driver was at fault.
the owner of the car with insurance will be responsible
NO!
Insurance follows the car, not the driver. As long as the car is insured and you have permission from the owner to drive it, you are covered.
A non insured driver may be held liable for the accident. Insurance is a requirement in the majority of states.
If the uninsured driver had the permission of the insured driver to operate the vehicle then NOTHING will happen to the uninsured driver. In fact, in this case he or she is not an uninsured driver at all. The insurance follows the vehicle first, the driver second.
Proably not, except of course you need to get insurance, luckily this one wasn't your fault
