In a recent meeting with Tom Mattson of Eureka Public Works, the speed trailer was recommended as a great multifaceted traffic calming device. Now, I thought this was an obvious choice as a quick and low-cost solution because the City just had to drag one out to a problem stretch of road and turn the thing on. Boy did I learn different. NOT ONLY does a speed trailer show people how much faster over the speed limit they're going, it will also sit there appearing 'off' to passing drivers for days when first set at a location and be taking important data on speed and time of day to be reported to California Highway Patrol.
