Drivers on I-80 Friday morning may have noticed a lot of emergency vehicles at the Iowa DOT’s Van Meter weigh station.
Emergency crews were called in after a plume of smoke came out of a semi-trailer during a standard check.
“They of course closed it and secured the scene and evacuated everyone,” says Cpt. Robert Johnson with the Iowa DOT and Motor Vehicle Enforcement.
Around 9:00 a.m. a semi truck pulled up to the weigh station, just a mile east of Van Meter.
Des Moines Hazmat was called in to check out why the smoke came out of the back of the trailer. They first thought it was a sulfuric and hydrochloric acid mix, and the station was shut down as a safety precaution.
After a couple of hours, crews didn’t find any hazardous materials, and said that the truck had been carrying empty containers.
The station is back open.
