A drug driving solicitor offers specialised assistance and legal advice to individuals who have been accused of driving under the influence of drugs in the UK. The Road Traffic Act expressly prohibits driving or being in charge of a vehicle whilst under the influence of alcohol or drugs.
In the UK, it is illegal to drive or attempt to drive if the individual is under the influence of illegal drugs and/or is under the influence of controlled drugs (over a prescribed limit). The role of a drug driving solicitor in London is to provide legal assistance in these situations.
Our driving solicitors in London include lawyers who specialize in the Road Traffic Act and offences that involve driving or attempting to drive while unfit through the consumption of alcohol or drugs.
Like our drink driving solicitors in the UK, our drug driving solicitors can intervene as soon as you have been accused of a drug-driving related offence.

How are prescription medicines treated in the UK in relation to driving?
Driving while under the influence of legal drugs is not permitted in the UK when the concentration of the said drug(s) influences one’s ability to drive.
Many types of medicines can alter the patient’s ability to operate a vehicle, including diazepam or lorazepam, or amphetamines. Although these are examples of drugs that can also be administered illicitly, they can be prescribed for certain types of conditions such as ADHD or depression (as per the doctor’s indications).
If you are taking drugs that can alter your ability to drive, you can talk to our drug drive solicitor to find more about the implications of driving while not following the medical advice you have received for their proper use.

Are there mitigating or aggravating factors for drug driving in the UK?
Like in the case of mitigation for drink driving, some factors can contribute to a lesser punishment in the case of individuals who are found guilty of driving under the influence of drugs.
A new section that is proposed for insertion into the Road Traffic Act refers specifically to factors that can reduce seriousness. Our driving offence solicitor lists some of the mitigating factors that can apply in this situation:
- No previous convictions or no relevant or recent ones. Understandably so, this cannot apply in the case of high risk offenders;
- Driving for a very short distance;
- Genuine emergency or a genuine misunderstanding when it comes to drug dosage and/or administration;
- The defendant is of good character or lacks maturity;
- The defendant has a learning disability or a proven, serious medical condition for which the drug was administered as a long-term or intensive treatment;
- The individual is the primary or the only caregiver for one or more family members.
As per the sentencing rules, when sentencing persons aged 18 to 25 years (typically referred to as young adults), emphasis should be placed on the mitigating factor relating to lack of maturity.
For a person who shows remorse, this can be counted as a mitigating factor, however, the court should never treat lack of remorse as an aggravating factor as this can present itself in many ways and in different manners from one individual to another. This could also apply in the case of drink driving, as our drink drive solicitor can explain upon request.
As part of the aggravating factors, it is worth noting that the following are taken into account:
- Previous convictions of the same nature or that are relevant to the conviction in course;
- The drug driving offence is committed while the individual is on bail;
- There was a high level of pedestrian traffic in the area in which the defendant drove while unfit through drugs;
- The person was not driving alone, instead, he or she was carrying passengers;
- The person was involved in an accident.
Please note that the list above is not an exhaustive one and other criteria or factors can play an important role when judging the seriousness of drug driving in the UK.
At the same time, we remind individuals that, in some cases, a drug rehabilitation course may be available in much the same way as a drink-drive rehabilitation course. Our team can give you more details upon request.
