Which of the following is NOT one of the four most common unsafe driving practices?

Neglecting vehicle maintenance is not typically classified among the four most common unsafe driving practices. The primary unsafe driving practices focus on behaviors that immediately affect driver control and safety on the road, such as distraction, drugs/alcohol use, and speeding.

Distraction refers to any activity that diverts attention from driving, which can include texting, talking on the phone, adjusting the radio, or even conversing with passengers. Driving under the influence of drugs or alcohol significantly impairs judgment, coordination, and reaction times, making it one of the leading causes of accidents. Speeding, or driving above the speed limit, increases the distance required to stop and reduces the driver's ability to steer safely around obstacles.

While neglecting vehicle maintenance is certainly important for safe driving and can lead to breakdowns or failure of vital systems (like brakes or tires), it is not a behavior directly related to the act of driving itself. Therefore, it does not fit into the same category of immediate, reckless actions that characterize the other options.
