A storm chaser filmed a trucker escaping through his overturned rig, after it was blown over by strong winds on Thursday evening.

The incident happened in New Cordell, Oklahoma, and was the third overturned truck witnessed by Jesse Post, a storm chaser for the National Weather Service.

Post says he pulled up to the overturned truck, expecting to conduct a search and possible rescue, when the trucker casually exited the vehicle through the shattered windshield. The driver then gave Post (and the camera) a thumbs up to indicate he was okay.

Post shared the video on Facebook and wrote the following description.
