It depends on the charge.
Cars can not be leased without having an actual license. A learners permit is only to be used for practicing to drive to receive an driver's license.
No they won't. A learners permit is not a valid license. They shouldn't be driving without a licensed driver. The owner of the car can be held liable. They can be sued for allowing an unlicensed driver, drive their vehicle.
how do i get car insurance with just my learners permit?
No, you can not get insurance unless you have at least one licensed driver on a policy.
Not in every state. Check your driver's Ed. book to be sure.
You must either have a driver's license or be insured under a licensed driver's insurance. If you are a minor, your parents can add you to their car insurance.
Depending on the state, all states allow properly licensed young drivers with a learners permit to operate a vehicle. This is to assume that the young driver is listed on the policy as he should be as a driver on the policy.
can you buy a new car with learners permit?
By yourself it is illegal. Just like your permit when you started driving a car you have to have a properly licensed driver with you.
Depends upon local laws.
No you can't. It is still illegal, but people still do it.
