The driver tested positive for cocaine and cannabis.

Cavan-Monaghan Garda Division say substances, such as alcohol, could still be in people's system the next day.

Ten drivers were arrested on suspicion of drink driving and one arrest was made for drug driving.

One driver tested positive for cannabis, with another testing positive for cocaine, and a third having alcohol in their system.

A JPC meeting was told the sharp increase could be due to people feeling safer in coming forward.

One of the drivers was drink-driving and is currently disqualified from driving for eight years.

Further enquiries established that the motorist was an unaccompanied learner permit holder.

Gardaí have reminded the public to never drink and drive.
