A 2020 study conducted by INRIX, private company that analyzes traffic patters, behaviors and congestion, showed that as traffic levels returned to normal during the three-month period August to October 2020, growth in collisions (57%), outpaced the growth in miles traveled (22%) resulting in a higher than normal collision rate during this period.In France, the Ministry of Interior reported that traffic incidents, crash-related injuries, and fatalities dropped in 2020 compared with 2019. Fatalities dropped 21.4%, injuries dropped 20.9%, and incidents overall dropped 20%. In the same report, the ministry reported that the number of vehicles on the road dropped by 75%, which would indicate that the rate (incidents per vehicle-mile) in fact increased. Other
Other possibly hazardous factors that may alter a drivers soundness on the road include:

Irritability
Following specifically distinct rules too bureaucratically, inflexibly or rigidly when unique circumstances might suggest otherwise
Sudden swerving into somebodys blind spot without first clearly making oneself visible through the wing mirror
Unfamiliarity with ones dashboard features, center console or other interior handling devices after a recent car purchase
Lack of visibility due to windshield design, dense fog or sun glare
People-watching. Traffic safety culture, a variety of aspects of safety culture could impact on the number of crashes. Prevention
A large body of knowledge has been amassed on how to prevent car crashes, and reduce the severity of those that do occur.
Types of collision include head-on, road departure, rear-end, side collisions, and rollovers. Many different terms are commonly used to describe vehicle collisions. The World Health Organization uses the term road traffic injury, while the U.S. Census Bureau uses the term motor vehicle accidents (MVA), and Transport Canada uses the term "motor vehicle traffic collision" (MVTC). Other common terms include auto accident, car accident, car crash, car smash, car wreck, motor vehicle collision (MVC), personal injury collision (PIC), road accident, road traffic accident (RTA), road traffic collision (RTC), and road traffic incident (RTI) as well as more unofficial terms including smash-up, pile-up, and fender bender. Some organizations have begun to avoid the term accident, instead preferring terms such as collision, crash or incident. This is because the term accident implies that there is no one to blame, whereas most traffic collisions are the result of driving under the influence, excessive speed, distractions such as mobile phones or other risky behavior.Historically, in the United States, the use of terms other than accident had been criticized for holding back safety improvements, based on the idea that a culture of blame may discourage the involved parties from fully disclosing the facts, and thus frustrate attempts to address the real root causes. Health effects
Physical
A number of physical injuries can commonly result from the blunt force trauma caused by a collision, ranging from bruising and contusions to catastrophic physical injury (e.g., paralysis), traumatic or non-traumatic cardiac arrest and death. Psychological
Following collisions, long-lasting psychological trauma may occur.
