| Figures obtained by the Tele under Freedom of Information legislation also showed 49 drivers were charged with such offences in 2008 and 50 in 2007.
Sergeant Rachael Francis of the road policing unit said that, in some cases, around half of arrests in connection with driving while unfit through both alcohol and drugs come after tip-offs from the public.
She said it was vital people continued to inform officers if they saw anyone on the roads whom they felt might be a danger to themselves or other road users.
She said, “I would always encourage members of the public to phone us if they encounter any driver who they suspect is driving under the influence of drugs.
“Every year, we run campaigns urging them to do so.
“I would reiterate that message and commend those members of the public who have phoned us in the past to report a driver.”
Currently, specially-trained officers must carry out preliminary tests on drivers who they believe to be unfit to drive due to drugs.
A series of examinations are used to determine whether the officer believes the driver is impaired.
If the driver is believed to be guilty, they will be requested to report to a police station for a medical examination and a blood sample may then be tested.
However, Sergeant Francis said many people were unaware of exactly which substances could render them unfit to drive.
She said, “Different drugs affect you differently. It’s not only illegal drugs that can affect your ability to drive but also many prescription drugs, so it’s very important drivers read any guidance that comes with medication.
“If you are found guilty of driving under the influence of these drugs, you will still be held responsible for your actions. The effects of many drugs are also exacerbated by alcohol.
“I’ve heard some people say they feel they are better drivers when they are under the influence of alcohol or drugs but they actually make you less likely to react to situations.”
A spokesperson from the Royal Society for the Prevention of Accidents also expressed concern at the figures.
He said that in 2008 at least 56 fatal crashes in the UK involved a driver under the influence of drugs.
He said, “There is a perception that while drink-driving is unacceptable, drug-driving is not so much of an issue but that’s not the case. It can still cause injury and loss of life on our roads.
“Something as simple as a hay fever tablet can slow your reaction times. I would encourage anyone who is taking medication to refrain from driving if they feel they may be affected in this way.” |
