Which of the following is a requirement for collector multi-vehicle coverage?

Collector multi-vehicle coverage is specifically designed for enthusiasts who own multiple vehicles that are considered collector or antique cars. A key requirement for this type of insurance is that typically, only one of the vehicles can be driven on the road at any given time. This stipulation helps to ensure that the vehicles are maintained in excellent condition and are not used as daily drivers, which could increase the risk of wear and tear or accidents.

This requirement reflects the nature of collector vehicles, which are often not used for regular commuting. Conversely, covering multiple daily-driven vehicles would not align with the purpose of this specific insurance type, which is focused on preserving the value and condition of collector items. Thus, the stipulation that only one vehicle can be on the road at a time is an essential aspect of maintaining the integrity and protection offered by collector multi-vehicle insurance.
