Event organizers say that they're worried about highway safety -- and their jobs.

A group of truckers gathered at the state capitol in Missouri yesterday in support of legislation that they say is necessary to save their jobs from being lost to autonomous driving technology.

On Tuesday, August 20, a group of truck drivers rallied at the state capitol building in Jefferson City, Missouri, as part of the “Jefferson City Parked Protest” meant to raise awareness about the dangers of driverless trucks. About 20 industry stakeholders and nine trucks were present for the protest, organizers say.

Part of the purpose of the event was to show support for an upcoming bill being created by Rep. Mike Moon that could ban driverless truck technology from Missouri entirely. The bill is expected to debut sometime in October.

The event was organized by veteran owner-operator Bill Bogar.

Bogar told KRCTV that he is worried about the impact that driverless truck technology could have on the job prospects of the men and women of the industry: “This is my job. I mean, once these things come in, I’m done; I’m out. Most of these people coming in today are literally a week out of being out of business.”

The drivers also raised concerns about the impact of driverless truck technology on highway safety.

Another trucker protest organized under the name “10-4” is being planned for October 4 at the National Mall in Washington, D.C.
