Responding at night brings a whole host of challenges but equally can sometimes be a lot easier. A lot less traffic, easily seen from a long way off and more time for everyone to react; as shown here with some very good examples of awarenss from those I approach. This was late at night and so my use of sirens is minimal. I'd be curious to here from other responders about their night time use of the two tones and equally, for non-responders, do you think they should be used at night more? Stay safe all. C.
