To ask the Secretary of State for Transport, what evidence his Department holds on the effect of the number of roadside drug testing on the number of traffic accidents; and what assessment he has made of improvements in road safety since the introduction of roadside drug testing.
The Department has contracted a researcher to evaluate the effect and impact on road safety of the new section 5A offence, which will include the use of roadside testing. We expect to publish their final report in 2017. The effectiveness of the recent THINK! 2016 drug drive spring campaign which refers to the use of roadside drug testing will also be evaluated and a report will be published in the summer 2016.
