如果当时警车是停着的，那么它就不是approaching emergency vehicle. 这个罚单是错误的。
即使按照41-6a-904(2) stationary authorized emergency vehicle，你也可以argue你已经减速并且当时换道不安全。
41-6a-904(2) The operator of a vehicle, upon approaching a stationary authorized emergency vehicle that is displaying alternately flashing red, red and white, or red and blue lights, shall:
(a) reduce the speed of the vehicle;
(b) provide as much space as practical to the stationary authorized emergency vehicle; and
(c) if traveling in a lane adjacent to the stationary authorized emergency vehicle and if practical, with due regard to safety and traffic conditions, make a lane change into a lane not adjacent to the authorized emergency vehicle.
fail to yield or stop upon approaching emergency vehicle
