"Nguyen is one of several residents of the NewHolly neighborhood in Southeast Seattle who tried forcing the issue of traffic safety by taking matters into their own hands.
About six weeks ago, they installed eight rubberized yellow speed humps - purchased online for $900 - on two of NewHolly's busiest streets.
They said they acted because the city would not. A city Department of Transportation crew on Wednesday removed the illegally installed devices.
'The individuals who installed these speed humps may have been trying to make a point, but they were creating a hazard and causing potential problems for other users,' such as emergency vehicles and bicyclists, said Rick Sheridan, department spokesman."
