Motorists across the UK could face driving bans and unlimited fines for taking prescribed medication that impairs their ability to drive. While it is well known that driving under the influence of alcohol or illegal drugs is illegal, many drivers may not realise that legal, prescribed medicines can also lead to penalties under certain circumstances.
Official guidelines state that legal drugs include those prescribed by a doctor or healthcare professional, as well as over-the-counter medicines. Some individuals rely on these drugs to manage health conditions or short-term infections. However, it is essential to check whether these medications impair driving ability.
If police suspect a driver is under the influence of drugs—whether legal or not—they can pull them over and conduct a field impairment assessment. This may include tests such as walking in a straight line. A conviction for drug driving can result in a minimum one-year driving ban, an unlimited fine, and in severe cases, a six-month prison sentence and a criminal record. The conviction remains on the driving licence for 11 years.
In the most serious cases, causing death by careless driving while under the influence of drugs can lead to life imprisonment. A drug driving conviction can also significantly increase car insurance premiums and create employment issues for those whose jobs involve driving, as employers can see the conviction on the licence.
Drivers prescribed medication should ask their doctor about potential impacts on driving. Most medications include an information leaflet or packaging that advises on driving risks. It is also recommended to discuss with a doctor if prescribed any of the nine specific medications listed in the full government regulations.
