RPU says it seems to follow similar trends in the UK
More arrests have been made for drug driving so far this TT than drink driving, according to police here.
Anyone caught under the influence of drugs can be banned from driving for two years.
In the UK, significantly more drug-driving swabs are returning positive results despite more roadside alcohol tests being carried out.
