Both directions of Interstate 55 northwest of New Orleans are closed after a series of 25 multi-car pileups killed two people in zero visibility, according to the St. John the Baptist Parish Sheriff.
Wildfires in the drought-stricken state have been burning all summer. The combination of smoke and fog turned deadly.
The safest thing you can do is pull well off the road, turn off your lights, and wait for the fog to pass.
Also get out your phone because you can sell the footage of the subsequent accident to news channels.
