Minimum Auto Insurance Requirement – Leased Vehicles:
Most automobile leases will require you to have greater auto insurance coverage than your state's minimum liability requirements. You will probably have to purchase liability coverage with bodily injury maximums of $100,000 per person and $300,000 per accident, and $50,000 for property damage liability (also known as 100/300/50

Also, you'll probably be required (by the lease) to buy collision and comprehensive insurance to cover any losses due to fire, theft, vandalism, civil riot and collisions with animals. Both coverages require a deductible, which may be subject to a cap.
