I will talk mainly about drug-driving because that has been the largest part of our debate, but I will pick up on the points that have been made in relation to other amendments.
On drug-driving, it is important that we consider carefully any extra burdens that we place on the police, the Crown prosecutors and the Courts Service when introducing a new offence. The Government published an impact assessment in May last year that considered those issues. It shows that removing the requirement to prove that a driver is impaired will make it easier to enforce the law against drug-drivers.
In 2010, about 40% of the proceedings in magistrates courts for driving while impaired through drugs were withdrawn or dismissed. The comparable figure for exceeding the drink-drive limit is just 3%. In addition, research for Sir Peter North’s review of drink and
drug-driving law found that in one police force, only 35% of positive preliminary impairment tests led to findings of guilt at court in 2008 and 2009. It is clear, therefore, that the existing law on drug-driving is unsatisfactory, resulting in costs being incurred unnecessarily by the police, the CPS and the courts.
The new offence will reduce the wasted time, expense and effort involved when prosecutions under the existing impairment offence fail. It is not surprising, therefore, that the new offence is supported by the Association of Chief Police Officers. ACPO has been fully involved in the development of the proposal and is fully aware of the resource implications for the police.
Depending on the level at which specified limits are set and on the drugs specified for the offence, it is possible that introducing the new offence, which does not require proof of impairment, will increase the number of proceedings against drug-drivers. However, based on the Government’s estimates, those costs will be more than offset by savings from fewer road deaths and serious injuries. Indeed, the impact assessment published in May 2012 records an overall net saving of some £86 million over a 10-year period.
I acknowledge that, as the hon. Member for Walthamstow (Stella Creasy) said, there is still work to be done and that getting the technical details right is difficult and important. Although she said that this work is being done at the last moment, we do not envisage the offence coming into effect until the later part of next year, so there is time to get the details right. The Department for Transport and, where relevant, the Home Office will be concerned to ensure that the details are in place.
The hon. Lady asked about police equipment and training to support the enforcement of the new offence. Equipment was also mentioned by the hon. Member for Clwyd South (Susan Elan Jones). We have already granted type approval for the first station-based drug screening device for use in enforcing the existing impairment offence. We are also committed to type approving roadside devices for use in enforcing the new offence. Work on that will be taken forward once we have determined the drugs to be covered by the new offence and the specified limit for each drug. Our aim is to have approved roadside devices available as soon as practicable after the commencement of the new offence. As hon. Members will know, training on the use of new equipment is an operational matter for chief officers in consultation with roadside drug-testing device manufacturers. I acknowledge the validity of the observation made by the hon. Member for Walthamstow that the Government do not have the answers to every question, but I hope that I can reassure the House that the work is ongoing.
