It happened in the parking lot of Iowa Auto Rebuilders in Waterloo around 6:15 am.
The business wasn't open yet, but a few people were already at work.
"I thought someone was driving by on the highway, didn't feel right, and called 911," said Rick Popelka, an employee at Iowa Auto Rebuilders.
He wasn't wrong...sort of.
When he came to work Thursday morning, all was normal for the first five minutes or so, then he saw flashing lights in the parking lot.
"Five minutes later, there was an ambulance and a fire truck right where I pulled in the morning," said Popelka, "there was a vehicle with it's flashers on, I thought possibly someone got hurt."
Popelka says he saw a man run out of the car with some belongings and jump into the ambulance.
He offered to help, but says there wasn't much he could do.
It was a strange morning for everyone involved.
Popelka and the rest of the employees say they're glad their parking lot could be of service, and hopes the new family is ok.
The woman was taken to an area hospital, there is no word on her condition.
Firefighters say "roadside births" happen more often than many think.
