Not a speed trap but a Stop sign advisory. Livermore PD may sit on Epson street (between Holmes & Arroyo) and watch for cars going either direction on Concannon Blvd to make sure they come to a complete stop. Eastbound on Concannon toward Tesla Road is more targeted; if you are westbound heading toward Holmes, you should see the police car/motorcyle and no excuse to get stopped. Pause for at least 1 second after coming to a complete stop, otherwise the officer will cite. I was behind 1 driver slow then roll through and he was pulled over.
