No
Yes, it is illegal to drive without car insurance. You may be covered on your family's insurance plan, however, so I would discuss it with them.
You have to list the drivers covered to drive your car on the policy. If not he is not covered.
As long as you are sure they have insurance and if you are listed as a drive on such insurance policy. If these cases are both yes then you will be covered under their insurance as long as you have permission to drive the vehicle.
Anyone you give permission to is covered on your policy. Family members are certainly covered, even step children no living with you. Do not use this availability as primary insurance for them though. They should be listed on the residential parent's policy.
nope
Because they have found that you both are at the same address and your boyfriend has not scheduled you as a covered driver on his insurance policy. All auto insurance contracts require disclosure of other household members and that the insured declare these other household members as covered or not.
If you are a permissive driver (given permission to drive the vehicle by the named insured), your accident would be covered under the owner of the car's policy. The insurance follows the vehicle, not necessarily the driver. You might want to check the owner's policy. I've seen a clause that specifically excludes damage caused by another vehicle insured by the same person.
If you own a car and buy insurance to cover it, you are covered although the insurance is on the car. You can allow other people to drive the car and they will then be covered even if they don't have insurance.
It is not automatically covered. You must call your insurance company and add the car to your policy.
If you have insurance on a car anyone who you give permission to drive the vehicle is covered under your insurance. This is normally covered when insurance companies ask if there will be any other drivers for the vehicle.
passengers in my car should be covered since the california car insurance law requirement does not distinguish as to which person is covered by bodily injury liability insurance
