I asked this question a couple of months ago which in turn was based on a question asked by another user. I found the original question while looking for answers following a real-life brush with the Road Traffic Act though which I'm still thinking about. In Summer last year, I was working at my allotment when my parked car was hit. I was not in the car at the time and, although we actually heard the bang, we only found out the car had been hit when we were walked back from our plot and saw it. The other driver stopped and, because he was complaining of neck and back pain, an ambulance had been called. When an ambulance is called to a road accident in the UK the police are also despatched. The police arrived and decided on breath tests all round because there was a moving vehicle involved. I was a bit puzzled by this because neither my wife nor I had even been in the car at the time but, because we hadn't been drinking, I wasn't too bothered. In turns out while we were waiting for a breathalyser to be dropped off by another unit, their sergeant back at the station said it wasn't necessary to test us and we were free to go.
However, it's not unheard of for Mrs BWFC and I to drive to the allotment, grill a couple of steaks and share a bottle of wine then leave the car and walk home. If this had been the situation, and the officers had a breathalyser with them, there could have been a different outcome. If I had been asked to do a breath test and done it, I would very likely have over the limit which is an offence. If I'd politely but firmly said words to the effect of "on your bike, I wasn't even in the car", I'm then failing to provide a sample, which is also an offence.
My understanding is that there is no mitigation for drink-driving but there is a "reasonable excuse" defence for failing to provide and not driving is one of the possible excuses. However, there is no guarantee that the I would be cleared if I were to go down that road. How could I avoid committing an offence in this situation?
It seems that the only options are take the drink-driving charge which in my case would automatically result in loss of my job or roll the dice in the criminal justice system.
