Today, 9 October 2017, marks the fiftieth anniversary of the breathalyser. In recognition of this, the Parliamentary Advisory Council for Transport Safety (PACTS) has called on the UK Government to renew the fight against drink driving. After a long period of decline in drink drive death and injury, progress seems to have stalled since 2010. Worryingly, breath testing by police has fallen to a fifteen year low. A more ambitious and comprehensive approach is needed that takes account of resourcing realities and uses intelligence and technology better.
