A study from the AAA Foundation for Traffic Safety indicates that a few hours of sleep can greatly increase or decrease the risk of someone ending up in a car accident. Using data from the National Highway Traffic Safety Administration's National Motor Vehicle Crash Causation Survey, the foundation discovered that motorists should have at least seven hours of sleep to be able to safely operate a vehicle.
The National Motor Vehicle Crash Causation Survey contains information from police officers about crashes where emergency services had to be called or when a vehicle had to be towed away from the scene. Following accidents, police would ask individuals involved how much sleep they had gotten in the 24 hours leading up to the crash.
When compared to drivers who got seven hours of sleep, those who only got five or six hours of sleep in a 24-hour time frame were twice as likely to be involved in a car crash. Those who only got four or five hours of sleep were four times as likely to end up in a crash.
If someone is in a car crash, figuring out who was at fault may be very important. Such information may determine insurance company payouts and affect how much compensation the victim receives. To prove who caused a car crash, one may gather information from police reports and video from traffic cameras. A lawyer could assist an accident victim by helping to collect evidence and proving their case in court or to an insurance agency.
