I find it hard to believe any department allows their members to exceed the speed limit. As a former career firefighter paramedic we were told that if we exceeded the speed limit in a department vehicle during an emergency run and were involved in a crash we could be held accountable by Illinois law. That said there are times you really run hot but we did that knowing the law might work against us in the event of a crash. As far as lights, Illinois volunteers run blue lights with no limit on how many or what kind. Each department sets their own requirements or lets the member do as they please. A loooooong time ago as a young volunteer we returned to our station after a fire and there in the parking lot was a police car from the next town. He promptly arrested our Chief for driving at a high rate of spped recklessly through his town in his personal vehicle. We knew he drove fast but that was a wakeup call for all of us.
