This is just one of dozens of similarly terrifying and surreally hilarious sequences in The Road Movie, a feature comprised entirely Russian dashcam footage.

The Road Movie opens in limited release this Friday.
The unseen driver and his passenger react with shock and a few choice profanities, then decide to get out and help the truck driver.
