US impaired driving study reveals worrying results

A study from the US focussing on driving impairment from alcohol reveals results of major concern. According to the results, even drivers who are minimally impaired are more often to blame for fatal car crashes than the sober drivers they collide with. The study analysed data from crashes in the US and was led by UC San Diego sociologist David Phillips. The results were published in the British Medical Journal group’s Injury Prevention.

A study from the US focussing on driving impairment from alcohol reveals results of major concern. According to the results, even drivers who are minimally impaired are more often to blame for fatal car crashes than the sober drivers they collide with. The study analysed data from crashes in the US and was led by UC San Diego sociologist David Phillips. The results were published in the British Medical Journal group’s Injury Prevention. In all the study examined 570,731 fatal collisions, from 1994 to 2011.These showed that drivers with BAC 0.01 – well below the most common legal limit of 0.05 – are 46% more likely to be officially and solely blamed by crash investigators than are the sober drivers they collide with. The authors also found no “threshold effect” – “no sudden transition from blameless to blamed” at the legal limit for drink driving. Instead, blame increases steadily and smoothly from BAC 0.01 to 0.24.

    A new report by the Institute of Advanced Motorists (IAM) in the UK suggests that older drivers are as safe as drivers from all other age groups, and perhaps more so. The study shows older drivers have better attitudes to safety, deal with hazards better than young drivers and use experience to increase their safety margins on the road. The report reveals that drivers over 75 react just as quickly as other age groups when a vehicle emerges from a side road or if the car in front brakes suddenly on a rural r

    Safety and autonomous vehicles exercised the minds of some of Europe’s senior police officers at the recent TISPOL European Traffic Police Network Conference in the UK. The European Union looks like missing its target of halving the number of people killed on its roads each year by 2020. Just when European police forces are trying to get back on target, along comes the autonomous vehicle with all its inherent safety issues.
