What happens when a leased vehicle is destroyed in an accident and there is no insurance?

Usually, the lease car is required to be insured ... and the lease is most likely dependent on continued auto insurance being in force. If the car was destroyed (totalled) and there is no insurance to cover the loss, the car is then gone, but NOT the lease payments ... You will still be required to pay the lease as agreed upon ... would have been far cheaper to have had insurance.
