The three leading causes of fatal collisions are__________________.

The three leading causes of fatal collisions typically include:

1. Distracted Driving: This encompasses any activity that diverts attention from driving, such as texting, talking on a phone, eating, or using in-car entertainment systems. Distractions can significantly impair a driver's concentration and reaction time.

2. Speeding: Driving at speeds higher than the posted limits or too fast for conditions dramatically increases the likelihood of accidents and reduces the time available to react to hazards, thus increasing the severity of collisions.

3. Driving Under the Influence: Operating a vehicle while impaired by alcohol or drugs (including prescription medications) greatly reduces a driver’s ability to operate the vehicle safely. This leads to poor decision-making, slower reaction times, and impaired motor skills.

These factors consistently contribute to the majority of traffic fatalities, highlighting the critical importance of safe driving practices.
