What does Roll Over Protection System (ROPS) aim to prevent?

The Roll Over Protection System (ROPS) is specifically designed to prevent injuries that occur during vehicle overturns or rollovers. ROPS provides a safety structure that protects occupants in the event of a rollover by maintaining a protective space around them, thereby minimizing the risk of serious injuries or fatalities. This system is commonly found in various vehicles, especially those used in construction, agriculture, and rescue operations, where the risk of rollover is significant.

The other options do not align with the primary purpose of ROPS. While high-speed accidents, mechanical malfunctions, and poor visibility can indeed pose risks in operational settings, ROPS is uniquely focused on the consequences of a vehicle's rollover, making option B the correct choice.
