LEAF Certification Practice Test 2025 – Comprehensive Exam Preparation

The Intelligent Driver Alertness (I-DA) system in the 2022 Nissan LEAF is specifically designed to monitor the driver's behavior and detect signs of inattentiveness, which are often associated with driver fatigue. The system analyzes various inputs, such as steering patterns and driver attentiveness, to evaluate whether the driver is adequately alert.

When the system identifies behaviors indicative of fatigue or inattention, it issues a warning to encourage the driver to take a break or regain focus. This feature aims to enhance safety by addressing one of the most critical factors in driving—driver alertness.

The other options relate to different safety systems or alerts within the vehicle that address issues like lane departure, speed limits, or seatbelt use, but those are not the focus of the I-DA system.
