US wants tougher drink driving rule, may lower blood-alcohol limit
WASHINGTON (AFP) - The US government wants states to crack down more on people driving under the influence of alcohol by lowering the permitted blood-alcohol limit.
It is now at 0.8 gram of alcohol per liter of blood.
The National Transportation Safety Board said Tuesday it should come down to 0.5. That would put the US in line with most other countries in the world.
The NTSB said research has found that with a level of 0.5 most drivers experience a decline in both cognitive and visual functions, significantly increasing the risk of a serious crash.
