Yes, All 50 U.S. states require that a driver carry the appropriate Financial Responsibility. There is No exception of law in any U.S. state for a learners permit.
A Drivers or Learners "Permit" is permission to drive and therefore a temporary license with certain restrictions.
You can obtain your own insurance or you can be covered under someone elses policy such as the vehicle owners or your parents or legal guardians insurance policy but you must have coverage.
If you are a minor then you can still obtain auto insurance, but due to contract law your parent or gaurdian will have to countersign the insurance application. It's almost always cheaper to be added to your parents policy. A Drivers Permit comes with all the responsibilities of anyone who operates a motor vehicle on public roads, including your financial responsibility.
Some Insurance companies have underwriting guidelines that do not require the insured to schedule a newly permitted child of the insured on the policy until after they have graduated from the learners permit to a full license. This has led many people to erroneously assume that this is a matter of law when it is not, It is simply the policy of that particular company not to charge you while your child is learning. So Make sure you check with the insurance company first.
In Texas a dealer is required by law to verify that you have Insurance before you can drive the car off the lot. The law does not require you be over 18, only that you have the proper insurance.
From a General Insurance Agent - Drive safe - Buckle up.
You would need insurance if you are the owner of the vehicle. Assuming that you are a teenager you cannot register a vehicle or purchase insurance in your name until you are 18.
The car would need to be registered to an adult and they would have to carry the insurance and list you as a driver.
You can lose everything you have if you have an accident and are not insured. The other party can obtain a judgment which can follow you for years.
However, some states make an exception of law for a learners permit. When our teenaged boys received learner's permits (the last in 2007) they told us that under Florida law, they were covered under our policy. We did not have to add them to our policy until they received drivers licenses at age 16. Other states may have different policies. Your insurance company or state Department of Motor Vehicles can provide definitive answers.
