The number of people killed in motor vehicle crashes in the United States increased in by 5.6 percent from 2015 to 2016. In 2016, 37,461 people were killed in crashes on U.S. roadways, compared to 35,485 the previous year. North Carolina’s fatality figures followed the national trend, with fatalities increasing from 1,379 in 2015 to 1,450 in 2016, a 5.1 percent increase. Many such fatalities result in criminal vehicular homicide charges, which number in the hundreds each year in North Carolina alone.
Investigators and prosecutors in such cases are increasingly relying upon the vehicle itself to tell the story of what happened during and just before the crash. Many vehicles driven today (and nearly all manufactured in the past five years) are equipped with an Event Data Recorder (EDR) installed by the manufacturer. An EDR, often referred to as a car’s black box, contains data related to various aspects of the car’s operation seconds before a crash, including its speed, whether the brakes were applied, and the position of its gas pedal. This kind of evidence can play a central role in the State’s attempt to show culpably negligent driving. But how may the State lawfully obtain EDR information? And, once obtained, how may it be introduced into evidence?
