What is the leading cause of traffic fatalities in California?

The leading cause of traffic fatalities in California is attributed to alcohol and drug use, commonly referred to as driving under the influence (DUI). When drivers operate vehicles while impaired, their judgment, reaction time, and overall ability to drive safely are significantly compromised. This impairment can lead to dangerous decision-making, such as speeding or failing to yield, and increases the likelihood of accidents that result in severe injuries or fatalities.

Statistical data consistently shows that a substantial percentage of traffic-related deaths involve intoxicated drivers, making DUI a critical focus for law enforcement and public safety campaigns. Efforts to combat this issue include stricter laws, sobriety checkpoints, and educational initiatives about the dangers of impaired driving. Understanding this context emphasizes the importance of responsible behavior behind the wheel, particularly regarding substance use, to enhance road safety and protect lives.
