Police forces in Hampshire and Isle of Wight, and Thames Valley, UK, are trialling the world's first roadside breathalyser capable of detecting nitrous oxide, commonly known as 'laughing gas' or 'hippy crack.' This innovative device can identify if a driver has inhaled the substance up to two hours before the test, posing a significant risk to road safety. If found guilty of driving under the influence, motorists could face severe penalties, including a two-year prison sentence. Authorities have noted an alarming rise in the use of nitrous oxide among drivers, particularly younger individuals, leading to dangerous driving conditions. Acting Superintendent Emma Hart emphasized the need for such technology, stating that current methods lack the ability to prove nitrous oxide inhalation, complicating prosecutions. The trial aims to demonstrate the effectiveness of this device in preventing drug-related driving incidents and ultimately saving lives on the roads.
