Welsh police forces have shown widely differing detection rates for new drug-driving offences.
Gwent Police failed to make any arrests at all for this offence in the first two months of its existence.
Dyfed Powy made five arrests in two months, South Wales 8 in the same period but North Wales caught 34 in two months.
The Institute of Advanced Motorists has revealed for the first time the true scale of drug-driving in the UK since new laws came into force – and showed that over 400 people a month have already been arrested for this offence.
The IAM made a Freedom of Information request asking every police force area in England and Wales for the number of arrests made for the new offence (of driving with a specified controlled drug in the body above the specified limit for that drug), since it was introduced on 2 March 2015.
The IAM’s findings show 902 drug-drive arrests in total were made by forces in England and Wales. On average police arrested almost one person every three days for this crime.
In addition the results that have come through have shown there is little consistency in testing and arrests across England and Wales, with figures ranging from 200-plus in one police force down to zero in others.
The Metropolitan Police recorded the highest number of arrests, with 214 in just over two months which equates to three drivers every day since the law was changed. Next up was Northumbria Police with 97, then Cheshire Constabulary with 70, Sussex Police with 58 and South Yorkshire Police with 55.
