Which form extends liability to physical damage when renting for vacation?

The option that extends liability to physical damage when renting a vehicle for vacation is the OPCF 28A. This form, known as the "Ontario Rental Vehicle Agreement Coverage," provides coverage for the insured when renting a vehicle. It specifically addresses the liability implications and the physical damage coverage associated with renting a vehicle for personal use during vacations or travel.

This form is important because it ensures that the insured has coverage for potential damage to the rental vehicle, which might not be included under standard automobile insurance policies. It helps protect the individual renting the vehicle from financial liability arising from accidents or damages that may occur while using the rental vehicle.

The other options do not specifically address the rental of vehicles for vacation purposes or do not extend the same type of liability coverage related to physical damage. For instance, the OPCF 27 is focused on coverage for loss of use, while the OPCF 38 is more about the coverage of rented trailers. Therefore, in the context of vacation rentals, the OPCF 28A is the appropriate form that provides the necessary liability protection.
