Which of the following is identified as a main cause of motor vehicle crashes among young drivers, even without alcohol involvement?

Inexperience and immaturity is a primary factor contributing to motor vehicle crashes among young drivers, even when alcohol is not involved. Young drivers often lack the necessary experience to make quick, sound decisions in various driving situations. This inexperience can lead to poor judgment and an inability to assess risks effectively, significantly increasing the likelihood of accidents.

Additionally, immaturity plays a crucial role, as younger individuals may underestimate dangers and be more prone to taking unnecessary risks on the road. This combination of limited driving experience and developmental immaturity often results in behaviors such as speeding, aggressive driving, or failing to adhere to traffic signals, which can lead to crashes.

While the other options, such as excessive distractions, high speed, and driving under pressure, can certainly contribute to accidents, they do not specifically encapsulate the inherent issues faced by young drivers in relation to their developmental stage and experience level. The emphasis on inexperience and immaturity highlights the need for targeted education and awareness programs aimed at addressing these specific challenges for younger road users.
