There’s really no valid excuse: if you drive a car, you need to have a dash cam. These affordable camera sit on or above your dashboard and record your surroundings as you drive. Why is that important? Should anything go wrong that cases you to get into an accident, you’ll have the entire incident recorded on video. That means if you’re not at fault and another driver lies to the police and says you were, you’ll be able to prove your innocence and potentially save thousands of dollars on tickets and on hiked insurance premiums. Right now, Amazon has a big sale going that knocks as much as $40 off four different top-rated dash camera models. Check them all out below.
