quotes a report from Motherboard: In September 2014, Mats Jarlstrom, an electronics engineer living in Beaverton, Oregon, sent an email to the state's engineering board. The email claimed that yellow traffic lights don't last long enough, which "puts the public at risk." "I would like to present these facts for your review and comments," he wrote. This email resulted not with a meeting, but with a threat from The Oregon State Board of Examiners for Engineering and Land Surveying [stating]: "ORS 672.020(1) prohibits the practice of engineering in Oregon without registration -- at a minimum, your use of the title 'electronics engineer' and the statement 'I'm an engineer' create violations." In January of this year, Jarlstrom was officially fined $500 by the state for the crime of "practicing engineering without being registered."
Since the engineering board in Oregon said Jarlstrom should not be free to publish or present his ideas about the fast-turning yellow traffic lights, due to his "practice of engineering in Oregon without registration," he and the Institute for Justice sued them in federal court for violating his First Amendment rights. "I'm not practicing engineering, I'm just using basic mathematics and physics, Newtonian laws of motion, to make calculations and talk about what I found," he said. Sam Gedge, an attorney for the Institute for Justice, told Motherboard: "Mats has a clear First Amendment right to talk about anything from taxes to traffic lights. It's an instance of a licensing board trying to suppress speech."
