When you're driving on the highway there is this part of the road on the very side that if you drive over it it makes a loud noise to tell the driver that they went over too far. My dad told me it was so that when truckers (or people who'd been driving for a long time) fell asleep It'd make them wake up and start driving again. I thought this until I was 11.
