(CBS News) — Getting enough sleep before you get behind the wheel could save your life.

Researchers at the Virginia Tech Transportation Institute found fatigue is a cause in 20 percent of accidents. That’s more than previous studies have shown.

They equipped 100 cars with cameras to monitor drivers. Data collected showed that people who drive while tired are four times more likely to get in a crash or near crash.
