如果我是警方律師，我會強調前車有警笛，後車有警燈，遵照謙讓守則，不應該有插入中間的行為

這是司機手冊中對後麵緊急車謙讓的方式：You must yield the right-of-way to the emergency vehicle. Pull over to the right (all the way to the curb if practical) and stop parallel to the curb. Before pulling back into traffic, be particularly alert for additional emergency vehicles
