Like almost all police officers I have had to deliver death messages. Some stand out, particularly the young and unexpected ones. I remember calling round a ladies house on a Saturday afternoon. She answered the door with two young children running around excitedly as a policeman was on the doorstep. Her and her children's lives fell apart after I told them their husband/father was in the mortuary having just been wiped out by a drunk driver. There are others I recall, such as the parents of the 16 year old boy knocked off his bike and smashed to bits by a drunk driver who could barely stand up.
I haven't become the virtuous non drinking driver and I will have a couple of drinks when I go out but I absolutely support the recent report recommending that the drink drive limit is reduced from 80 micrograms of alcohol in 100 millilitres of blood to 50.
A few years ago now I worked in custody and had the opportunity to test myself on the drink drive machine. I could drink four pints of beer in about an hour and a half before I reached the limit. There is no way that I am safe to drive after four pints and I would have been a severe risk on the road. You lose between 7 and 13 micrograms of alcohol every hour. This means I could actually drink five pints in two hours and possibly pass the test.
