Road Traffic Collisions

  • Reference Number: 1619
  • Date released: 30 January 2009

Request

  1. The number of road traffic collisions that resulted in death or serious injury and involved one or more drivers with a recorded blood alcohol level between 50 and 80 mg per 100ml of blood for each of the last 10 years, broken down by Police Authority. If you are unable to provide the information for each of the last 10 years, then your most up-to-date figures would be appreciated.

Response

In accordance with section 1 (1) (b) of the Act our response is provided below;

Number of qualifying Road Traffic Collisions (RTC)

Please find below the number of Fatal and Serious RTCs where alcohol was recorded as being a causation factor (not necessarily between 50 and 80 mg per 100ml of blood - see notes below).

Unfortunately, information relating to alcohol usage was only available for the past 5 years. The stats are as follows:

Fatal and Serious RTCs

Year Fatal Serious
2004 16 0
2005 11 64
2006 9 59
2007 3 48
2008 5 38

Details of the blood alcohol level of the individuals involved

The ability to provide data relating to blood alcohol level of an individual is hampered by several issues.

  1. This data is recorded manually in a file in the breath test room at each custody suite.
  2. The Mg of alcohol is also supposed to be present in the custody log in a person's custody record . This is a free text field that is not searchable in a reliable way. In order to locate the information reliably we would need to search under each occurrence, find the arrest record and then look within the custody log. This is a process that would exceed the limit. Also, we can not guarantee that in every case the Mg of alcohol will in fact be recorded in the custody log and so carrying out the search may not even provide us with answers for each case.
  3. If one of the drivers involved in the RTC is the fatality, the alcohol level would only be tested in the post-mortem. Therefore, the coroners would hold information on this.

Other factors to consider

A driver may be arrested for an offence at the scene and then whilst in custody placed on an approved device which would give a reading of ugs, which is alcohol in breath, so not exactly what was requested in any case.

The majority of drivers would have a screening breath test at the roadside, where breath screening devices before 2009 did not provide the police officer or the force with the actual breath test result in figures, only pass, warn, fail. It is not possible therefore to give anyone any figures for how many were between 50-80mg per 100ml as we will not hold this information.

All drivers in this range and below with a slight reading would show as negative or warn.

Therefore all the information requested is not held. To retrieve what little information we may hold is likely to exceed the appropriate limit, as it would require a search of all fatal post mortem results and all custody records following an arrest at an accident scene. The appropriate limit is defined in the Data Protection and Freedom of Information (Fees and Appropriate Limit) Regulations 2004, which is covered by statutory Instrument Number 3244 of 2004. Furthermore, section 12 of the Freedom of Information Act 2000 allows a public authority to refuse to respond to a request for information where the cost of compliance would exceed the appropriate limit as defined by the above mentioned regulations.

Some of this information may be held by Coroners if a sample of blood is taken from a deceased person as part of the post mortem investigation, however the HM Coroner's Office are not subject to Freedom of Information legislation.

For your information and in order to assist you, the Transport Research Laboratory (TRL Ltd) Crawthorne House, Nine Mile Ride, Wokingham RG40 3GA act on behalf of the Department for Transport by collating available blood/alcohol data for fatal road accidents only, after obtaining the information from Coroners in England and Wales, and the Procurator Fiscal in Scotland. TRL publish data prior to 2007 which can be obtained from leaflet LF 2104 held in the Reports and Publications Section at the following link:TRL
