I got breath-tested the other day.
It was at about 10pm last Thursday when I was driving home along Havelock Rd. I had been working late and just before I left for home, I had one beer with colleagues (and yes it was really only one beer) in the office.
When I first saw the blue flashing lights I thought there must have been an accident near where they are building the new cycleway. As I got closer, it became clear it was a roadblock. For some reason I became extremely nervous. It was completely irrational because there was no way I was over the limit after just one beer. Also, I was fully in control of the vehicle and my senses were not in the slightest impaired. If I had felt I was not able to drive, I wouldn't have. But for some reason or another I still felt anxious.
I needn't have worried at all. The very polite police officer - who must have been cold in the 2C night - greeted me and asked me to count to five while breathing into a handheld device. I did so and he said thank you and told me I could go. Simple as that.
I drove off feeling very relieved, but also, in a weird way, glad I had been stopped. I would rather go through a moment of irrational angst than not have the police out there catching the people who drive while drunk.
