Alongside the publication of 2023 drink-drive statistics in July 2025, we opened a survey for users to give us feedback on four areas:

• the proposed end to collecting data on blood alcohol levels in pedestrian, pedal cyclist and passenger fatalities
• the proposed end to publishing statistics on digital breath test results
• proposed changes to the methodology used to create drink-drive estimates
• renaming the publication to 鈥淩eported road casualties in Great Britain, drink-drive collisions鈥�

We received 4 responses from various users of the statistics, including policy colleagues in DfT and some users external to the Civil Service.

Pedestrian, pedal cyclist and passenger blood alcohol data

Regarding pedestrians, most responses were against the loss of blood alcohol data and users expressed an interest in understanding the full picture of how alcohol and drugs contribute to deaths on the road, especially as more people are encouraged to make non-motoring journeys. Therefore, we have decided to continue publishing statistics based on blood alcohol data for pedestrians.

Similar points were raised for pedal cyclists. It was also identified that that the statistics are relevant to policy work in DfT, so we have decided to continue publishing statistics based on blood alcohol data for pedal cyclists.

Opinions were split in regard to passengers, with half saying the loss of data wouldn鈥檛 affect them and half saying it would. Those in favour of keeping the data said that future analysis of collisions involving young drivers and alcohol could use these data. However, despite these responses, we believe that the burden of collecting these data from coroners outweighs the potential need for the data in the future. Therefore, we will stop publishing statistics based on blood alcohol data for passengers.

Digital breath test data

Most responses indicated that they were against losing data on digital breath test results. Users shared that these data have been useful to look into the different trends for drink-drivers by sex.

Despite this, the current coverage of the data is low due to low response rates from police forces. Also, a new data pipeline would need to be established if we were to continue publishing these statistics in order to clean and ingest the data, which would require significant resource from the Road Safety Statistics team. The team currently doesn鈥檛 have the capacity for this so we won鈥檛 be updating these statistics but we will review this decision in the future. If we do decide to update the statistics again, we will engage with police forces to try to increase response rates and therefore improve the value of the statistics.

Changes to methodology

All users who responded were in favour of the implementation of the proposed methodology changes. Therefore, we aim to introduce the changes in the publication of 2024 data. These changes will result in revisions to the data and these will be communicated clearly in the publication.

Renaming the publication

All users were also in favour of changing the name of the publications so we aim to publish 2024 data under the new name 鈥淩eported road casualties in Great Britain, drink-drive collisions: 2024鈥�.

Copy of the survey

Below is a copy of the survey we shared. If you did not get a chance to share your thoughts with us while the survey was open but the decisions above would greatly affect your work, answer the questions below and get in contact with us at roadacc.stats@dft.gov.uk.

Coroner data on passengers, pedestrians and pedal cyclists

We are proposing to make changes to the data collected from coroners which forms part of the annual drink-drive statistics, from 2024 data onwards. Coroner data provides information on blood alcohol levels of those killed in road collisions which is used in these statistics.

To reduce burdens on coroners who supply this information, we are proposing that in future data will only be collected for motor vehicle drivers in future.

Currently data is collected for all fatalities. However, only those that are motor vehicle drivers or riders are used in producing the estimates of drink-drive casualties as the drink-drive limits do not apply to pedestrians, vehicle passengers or non-motor vehicle drivers or riders.

As it stands, data on proportions of pedestrians, passengers and pedal cyclist fatalities with blood alcohol in excess of the drink drive limit is presented in table RAS2033. However, this shows that the sample sizes for these groups are typically small, and in many cases toxicology information is not available.聽It is likely that some coroners will test when alcohol is suspected to be present, which introduces the possibility of bias in these figures and potentially limits their usefulness.

Digital breath test results

We have not updated RAS2042, which contains data on the concentrations of alcohol detected in drivers鈥� breath in roadside breath tests, for 2023. This in part reflects a reduction in the volume of data provided by police forces in recent years.

We are also proposing the removal of this table in future. If these data are not being used, then we believe that the value to users that these statistics provide is outweighed by the work required to collect the data and produce the statistics.

Proposed methodology changes

We are proposing a change to the methodology used to produce the drink-drive estimates for fatalities. This will result in minor changes to the estimates but will make the statistics more robust. Technical details of the changes we are considering implementing are available, including a chart showing the potential impact on recent years figures.

Name of the publication

Currently, this publication is titled 鈥淩eported road casualties in Great Britain, involving illegal alcohol levels鈥� however, we don鈥檛 believe that this is clear or matches the language used when the statistics are discussed and reported. We are considering changing the name of this publication to 鈥淩eported road casualties in Great Britain, drink-drive collisions鈥�. We believe that this is clearer and aligns better with how users of the statistics would refer to them.

Any other feedback

We also welcome any other feedback on these statistics. For example:

• does the timeliness and frequency of the current publications meet your needs?
• are there additional topics or analyses you would like to see included in the annual publication?
• are there any additional breakdowns which could be included in the published data tables?
