Which endorsement would you refer to for permissions related to renting a vehicle?

The endorsement you would refer to for permissions related to renting a vehicle is OPCF 5. This specific endorsement, known as the "Permission to Rent a Vehicle," provides coverage for drivers who rent vehicles. It is essential because personal automobile insurance, typically, may not automatically cover rented vehicles, especially under circumstances stipulated in a rental agreement.

OPCF 5 ensures that the rented vehicle is treated similarly to the insured's personal vehicle in terms of protection, thus providing liability coverage under the terms of the policy. Without this endorsement, there could be significant gaps in coverage, which could leave the policyholder vulnerable to financial loss should they be involved in an incident while using a rental vehicle.
