Drug driving

The problem of drug-driving is growing fast.

The simple fact is that many drugs will affect a driver's ability to drive safely. And not just illegal drugs; some prescribed drugs can affect driving.

So far only small-scale surveys have been done. But these suggest that:

  • 18% of driver/rider fatalities had some form of illegal drug in their system
  • 6% of driver/rider fatalities had some form of prescribed drug in their system

This means that 24% of fatal crashes could involve drug-driving. Compared to 16% for drink-driving.

Testing for drug-drivers

The Police can now use Field Impairment Tests (FIT) if they think that a driver's ability is affected by a drug. The evidence they gain from FIT could be enough for a driver to be arrested.

FIT involves a range of specifically devised tests to check co-ordination, balance and understanding. Most tests ask the driver to perform simple tasks, like standing on one leg and walking a straight line.

Using FIT allows a police officer to accurately see what type of drug, if any, has been taken. The results could mean the driver is arrested and taken to a police station. A blood test would then be made to confirm what type of drug is in the driver's system.

Currently, the Police have no quick or reliable roadside test for the presence of drugs. Unlike the breathalyser test for alcohol, drug tests need a laboratory and can take days. Plus there isn't an agreed 'limit' for drug-driving, unlike the alcohol limit for driving.

Prescribed drugs

Any illegal drug will affect an individual's state of mind. It will reduce their ability to concentrate, make their reactions slower, and make them take risks they would not normally take. Just like alcohol.

But drivers also need to be aware that legally prescribed medications can affect driving ability. Even cough medicines and cold and flu remedies.

Some medication causes drowsiness, for example. And you may feel fine before you start driving, but once in a stuffy, warm car you could very easily feel tired and begin to lose concentration.

Always read the label and discuss the possible affects on driving with the prescribing doctor.

What does Kent County Council do to tackle this problem?

Kent County Council's Road Safety Officers discuss these issues on the young driver courses that we provide in secondary schools. We also promote and support national campaigns.
