A roll-over protection system is most likely to be found in which type of vehicle?

A roll-over protection system is specifically designed to enhance the safety of a vehicle in the event of a rollover accident. This system is particularly important in vehicles that have a higher risk of rollover due to their design or height. Convertibles, with their open-top design, are especially vulnerable during a rollover, as they do not have a solid roof that can provide structural support to protect the occupants.

The roll-over protection system in a convertible usually includes features like reinforced roll bars or other structural enhancements that can help prevent the roof from collapsing and provide additional safety for the occupants during such an event. This is a crucial safety measure, given that the absence of a roof can lead to serious injury in the event of a rollover.

In contrast, sports cars, high-end passenger cars, and passenger vans may have some safety features, but they do not typically require the same level of roll-over protection as convertibles due to their design, structure, and purpose. Therefore, the presence of a roll-over protection system is primarily a feature associated with convertibles.
