The number of drivers giving positive breath results in Lincolnshire has increased by almost 3% over the Christmas period, new figures show.
A total of 143 motorists were found to be over the limit on county roads, an increase of four cases from 2010 and the highest count since 2005.
But the Lincolnshire Road Safety Partnership said more drivers screened gave positive tests or refused to provide a sample, with fewer tests administered.
Lincolnshire Police also arrested five drivers over drink or drug driving between December 1, 2011 and January 1, 2012.
Comparing the full year figures of 2010 and 2011, there have been 11 less killed or seriously injured resulting from alcohol related collisions, but there have been 2 more fatalities, which did not occur in the campaign period.
“Whilst it is never good news to see what seems to be stagnation in the figures compared to a previous year, the trend in those still willing to drink and drive is falling,” said a statement from the Lincolnshire Road Safety Partnership.
“There will be a number of drivers who made a positive decision not to drink and drive but we cannot measure how many made that decision.
“What we will do for the future is, with high-profile campaigning and a robust strategy of enforcement, we ensure those drivers who drink and drive are placed before the courts and make the roads of Lincolnshire safer for all.”
