A parent or someone who already has a drivers license ONLY
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.
how do i get car insurance with just my learners permit?
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.
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.
