We have received two speeding fine for offences committed on the same day. On the day in question, my husband, my daughter and myself were out on family trip and all three of us took turns driving. Problem is, we don’t know who was behind the wheel when we were caught speeding.

I wrote back to ask for clarification as to who was driving, but the photos they have sent only show the number plates – it’s impossible to tell who was behind the wheel. My husband is prepared to take the blame, but this doesn't somehow seem right as he has 40 years driving experience with no speeding convictions at all. What should we do?
