Lake County Sheriff’s Police Det. Chris Covelli said speeding is a big factor in fatal accidents. So is distracted driving.

Covelli said drivers shouldn’t assume police won’t find out if you’ve been using your phone while at the wheel.

“Especially in very serious, critical, or fatal traffic crashes; what traffic investigators will often do is request subpoenas for cellular records to determine if cellular phones were in use during the time the crash occurred,” he said.

“Traditionally, Memorial Day through Labor Day is deemed the 100 deadliest days of driving, and essentially it’s the summer months. College students are home for the year, the kids are out of school, and there’s a lot more driving going on,” Covelli said.
