In 2015, there were 5,770 drink driving related accidents, with 980 of them being classed as ‘serious’. Needless to say, those 5,770 incidents could have been avoided if those drink drivers had just said ‘no’. So, the penalties are harsh and you could face points on your licence, imprisonment, a fine and a possible ban for driving while above the legal limit - which is increased to three years if it's your second conviction of that offence in 10 years.
If you are disqualified from driving, a judge might offer you a reduction in the amount of time you’re off the road for if you go on a drink driving course.
It’s also worth noting that if you’re asked for a blood sample and fail to do so, then it can be treated just as severely as a failed test and you could face an unlimited fine, a 12 month driving ban, and even 6 months in prison.
If you cause death whilst driving under the influence of drink, depending on the circumstances you could face 14 years in prison, an unlimited fine, points on your licence and a two year ban – plus an extended driving test before you can your licence back.
