Adjust Your Headrest to the Top of Your Ears

Most people never adjust their headrest after buying a car, leaving it too low. In a rear-end collision, a poorly positioned headrest creates a gap that turns the impact into a severe whiplash injury — your head snaps backward with nothing to catch it. The center of the headrest should align with the middle of your head (roughly ear height), and sit no more than 2-3 cm from the back of your skull. It takes 10 seconds to adjust, and it's the difference between walking away from a fender-bender and months of neck pain, or worse.
