What causes traffic accidents?

Traffic accidents are a major cause of death in the world, but often deeply misunderstood.

Some stats pony to driver error, others point to drinking and driving, texting or new drivers as the cause of death.  How do driving accidents actually break down?

Causes of Crash

One reason it's hard to tell is that lack of consistent data.  Luckily, a few landmark studies can help.  NMVCCS investigated a total of 6,950 crashes during the 3-year period from January 2005 to December 2007 - creating one of the most comprehensive causation of studies of accidents ever.

93% of accidents studies were caused by driver error.

Among these driver-caused related accidents, most often a misjudgment of speed or danger leads to accidents

Drinking and Driving

The 2005-2007 study did not attribute accidents to drunk driving.  However, looking at other studies, 7% of all traffic accidents involve alcohol use.  Due to the high speeds that these accidents occur, 31% of all traffic-related deaths in the US are due to alcohol-impaired drivers


An estimated 5% of crashes involve texting, while 21% involve drivers talking on handheld or hands-free cell phones.  This is up from 2007, where 18% of accidents involved some sort of interior distraction, most frequently phone use.


Among other associated factors, fatigued drivers were twice as likely to make performance errors as compared to drivers who were not fatigued.  

While drunk driving and texting gets most of the attention - we strongly feel that an underserved problem is addressing the limited information & attention all drivers have.    With the use cases we already cover, we believe we can stop over 50% of the accidents today

A simple heads up can go a long way!
