Experts are warning drivers to not be tempted to get behind the wheel after consuming alcohol this Christmas as they reveal that car insurance premiums rise by an average of 85% after a driver has been convicted of driving while under the influence of alcohol. The research carried out by insurance price comparison website, Moneysupermarket.com, found that on average, the cost of an annual car insurance policy would rise from £424 to £784 as a result of the main driver being caught driving while over the legal drink drive limit which works out as an increase of 85%. While the drink drive limit in the UK is 80mg of alcohol per 100g of blood, Drink Aware recommend not consuming any alcohol whatsoever if you know you will have to drive in order to avoid being caught out. They also advise arranging travel plans in advance if you do intend to celebrate with a drink over the Christmas period to ensure you have a safe way of getting home which does not involve you getting in the driving seat after a drink. Police in Scotland have even gone one step further in their bid to encourage designated drivers to stay alcohol free as they’re offering a buy-one-get-one free on soft drinks in Scottish pubs as part of their “Christmas Coke on Us” campaign.
