When it comes to driving with alcohol in your system there is simply no safe limit, the only safe amount is none at all. No two people react the same way with alcohol in their systems and everybody reacts to it differently, the factors that it depends on are size, weight, state of health and how long ago you ate anything.
Over 3,000 every year people on average are killed or injured in accidents involving alcohol, a large proportion being young drivers, aged between 17 and 29 one in six of which are driving over the legal limit. 12% are on their second conviction, the highest percentage are men aged 20-24. Drink drivers are on average twice as likely to have a criminal record for another or several offences. The police carry out over half a million breath tests every year and about 100,000 are positive for being over the limit. In a recent survey it was discovered that 44% of all drivers admitted to having driven with some amount of alcohol in their system and one in eight of those believed that they had been over the limit.
People often believe that they are safe to drive when they were actually over the limit, unfortunately, as alcohol gives you an exaggerated sense of self confidence, a driver under the influence is more likely to take risks while driving, increasing the likelihood of an accident. Also with most drinking going on at night when it's dark, the kind of driving conditions the average over the limit driver has to deal with are probably the most hazardous and demanding - the one time they most need top be sober to get home safely. There simply is no safe limit of alcohol intake when you are going to be driving. The only safe and sensible choice is to not drink if you are driving, if you are going to be drinking, then a designated driver who will not be drinking is needed or else use public transport.
The maximum penalty for drink driving is six months imprisonment, a fine of up to £5,000 and a ban for up to 12 months. -the average penalty for being over the limit while running a vehicle is up to 3 months imprisonment and a £2,500 fine plus a ban. An endorsement for drink driving stays on your license for 11 years, far longer than normal traffic offences. With such harsh penalties you would think that people would go to any lengths to avoid this but the attitudes to drink driving are somewhat skewed in the respect that most people agree that the penalties should be severe except when it is them or a friend or a relative that has been caught drink driving then they plead for leniency.
It seems that this is a social problem that will never go away until cars are made to drive themselves and are incapable of colliding, this may be the future for transport as these systems are being successfully tested in this country and in other countries, the most well known example being the google driverless car which has been accepted as legal and safe in several states as it has run for many hundreds of thousands of miles without a single collision. This would mean that drink driving accidents and road traffic accidents in general would become a thing of the past.
