Yes. Mike Hawthorn was killed in a road crash shortly after he had won the 1958 World Championship . His Jaguar crashed on a road known as the 'Hogs Back' near Guildford in Surrey.
"A serious accident was caused by the driver's negligence."
If there is no other vehicle involved in the accident, then the only person who can be at fault is the underage driver.
No, but if involved in an accident, even when not at fault, the drunk driver would still be guilty of, and could be charged with, DUI.
They would be charged
Yes they can.
Some do. I work for an insurance company and many will take ownership of the accident.
causing a serious accident while driving
Insurance follows the car, not the driver. If you had permission to use it you should be fine. If you were cited for a traffic violation, you should just pay it ahead of time and then apologize profusely to your friend, since you just raised his rates for several years. If there was an accident and it involved any serious amount of money / injury, shell out the $70 and ask an attorney.
the driver's license would be suspended.
He or she will get arrested and put in jail.
It depends on the circumstances and the legislation of the country concerned
Not really sure actually. In the eye of the law the accident will most likely be considered your fault.
