second permittee doctrine
second-permittee doctrine. Insurance. The principle that, when a third person is allowed to use an insured’s car by permission granted by someone else to whom the insured gave permission to use the car, the third person’s use of the car will be a permissive use, under the insured’s automobile-liability-insurance policy, as long as that use falls within the scope of the permission originally given by the insured. [Cases: Insurance 2666. C.J.S. Insurance §§ 1051–1052.]
