Let’s face it: Most of us hate driving on interstates. Between the traffic and weather — and sometimes both — these roads stress us out. And if you’re making a long drive, potentially across states, the whole experience may leave you exhausted.

Add on the risk of getting into an accident, and exhaustion is the least of your worries. You hold your breath, grip the steering wheel until your knuckles turn white, and don’t dare to take your eyes off the road. The tightness in your chest only goes away when you turn onto the exit ramp.

Unfortunately, not everyone makes it to that ramp. A recent study by Assurance IQ, an insurance policy shopping platform, reveals some unsettling statistics.
