Final answer:
The true statement is that collateral benefits are sources of entitlement outside of the automobile insurance policy. No-fault benefits indeed cover rehabilitation and therapy expenses, and the Family Protection Endorsement is not limited to single-vehicle accidents.
Step-by-step explanation:
The correct statement in the provided options is b) Collateral benefits are any sources of entitlement outside of the automobile insurance policy. Collateral benefits refer to entitlements that may come from other sources, such as health insurance, workers' compensation, or disability benefits, which exist separately from the benefits provided by an auto insurance policy. By contrast, limits on no-fault accident benefits are often regulated by provincial or state insurance laws rather than the Highway Traffic Act. Additionally, rehabilitation and physical therapy expenses are typically covered under no-fault benefits, making them payable when such an event occurs. Lastly, the Family Protection Endorsement is not just applicable to single-vehicle accidents; it extends to cover undersinsured or uninsured at-fault drivers in various types of accidents.
