Motorcycle Officers and Cars..along Railroad and Stanley between First Street and the 680 Freeway onramp at Sunol. Times of enforcement are during the morning and afternoon commute times. This road is used as a bypass for the 580 to 680 transition from Livermore to Sunol (680 freeway). Note, the speed limit is probably reasonable, however, most travel far in excess of it and the city of Pleasanton has decided that it is a lucritive way to enhance the city budget.
