Car accidents are among the leading causes of injury and death in California and throughout the United States. With Riverside being the most populous city of Southern California’s Inland Empire region, it is unfortunately home to hundreds of collisions every year.

However, of all drivers killed in motor vehicle collisions in 2019, 50% of those tested, tested positive for legal and/or illegal drugs. 

What Impacts Highway Safety? 

Several factors impact highway safety and lead to a rise in motor vehicle accidents, according to the National Highway Traffic Safety Administration (NHTSA): 

Population Growth

Riverside reached its highest population of 334,772 in 2021, with a population density of 4,120 people per square mile. More people mean more drivers and an increased chance of an accident. 

Older Drivers

Older Americans are involved in 13 percent of fatal accidents in the U.S. The traffic fatality rate of drivers 65 and older is 17 times higher than that of drivers 25 to 65 years old.

Young Drivers

Approximately 43 million drivers in the U.S. are between 16 and 24. Young drivers tend to be more aggressive than older drivers and are more likely to speed or drive while intoxicated. 


Denser urban populations lead many to seek affordable housing elsewhere. Longer commutes mean a greater risk of traffic accidents. 


Riverside is among the top cities with the worst traffic congestion in the nation. Some drivers respond to traffic by being aggressive, changing lanes frequently, speeding, becoming angry at other drivers. These and other unsafe driving behaviors are major factors in traffic accidents.
