Next to Dayton Library and Dayton Senior Center, which is across from Dayton Schools on Old Dayton Valley Rd.. Posted speed limit is 15 MPH. One or two Lyon county sheriffs vehicles will be monitoring all vehicles with radar, and pull over anyone going over 20 MPH. From 7AM to 4PM school days. I received a ticket for 20 MPH in 15 MPH zone at 10 AM, when there were no children, adults, pedestrians, cars or school buses visible on this stretch of road. 3 to more than 20 tickets are issued per hour. If you park at Dayton library and watch for an hour or so, you will see Lyon county sheriffs go after vehicles that their radar shows over limit that are more than 1/4 mile away and chase vehicle down in school parking lots. Sheriff’s vehicles facing East parked in front of Library issue tickets for failure to make a “wheels full stop” at stop sign East of library on Old Dayton Valley Rd. Your court date will be 2 months in the future because so many tickets have been issued and have taken up all the Dayton Court time available to handle your appearance before the court sooner. Please, Please 15 MPH, and full stop this area !!
