The number of drink-drive convictions on the Island has been dropping steadily for five years, according to figures revealed in the House of Keys today.

Home affairs minister Juan Watterson faced a question for written answer from Onchan MHK Zac Hall about the issue.

In particular, he wanted to know how many roadside and blood tests had been carried out and how many people had been guilty of drink-related motoring offences.

Mr Watterson revealed drink-driving and driving while unfit through drink or drugs convictions had been falling since 2007.

The data shows four offences – driving over the limit, driving whilst unfit, failing to provide a specimen and being in charge of a vehicle while unfit.

In 2007, almost 150 people were convicted of one of the four – but last year that figure had dropped to just 91.

But Mr Watterson said it wasn’t possible to give figures for the number of breath tests carried out by police because the equipment doesn’t indicate how many times it’s been used.

However, he added it was gratifying to see the number of convictions had been falling.
