A Texas man is trying to clear his name after he was arrested and cited for warning drivers about a speed trap.

Ron Martin, 33, defended himself in a court hearing Wednesday, claiming his warning was "the same thing as a speed limit sign," Dallas TV station WFAA reported.

"I just don't wear a uniform," he said.

Martin was arrested last October after police in Frisco saw him standing in the median of a six-lane highway holding up a homemade sign that read, "Police Ahead."

Officers had seen him holding the sign in the same median two other times that month.

There's no law in Texas banning people from warning drivers about speed traps. Police instead cited the city's ordinance that states that people holding or wearing signs for advertising must be on private property, according to WFAA.

Martin told Dallas TV station KDFW he's not opposed to speed traps, but is concerned about what he calls unsafe practices by the officers conducting the enforcement.
