Accused of drug driving? Get advice before court
Many people assume that a positive drug test means the case cannot be challenged. That is not always correct. Drug driving cases often depend on whether the police followed the correct procedure, whether the blood sample was handled properly and whether the laboratory result proves the allegation.
If you are unsure what happens after a failed roadside test, read our guide on what happens if caught drug driving. If you already have a court date, you should get advice before entering a plea.
A solicitor can review the paperwork and explain whether the case should be defended, whether further evidence is needed or whether the focus should be on mitigation.
What is drug driving?
Drug driving can include driving, attempting to drive or being in charge of a vehicle with a specified controlled drug above the legal limit. The law can apply to illegal drugs and some prescription medications.
A common charge is driving with a specified controlled drug above the legal limit. The offence is set out in section 5A of the Road Traffic Act 1988. In these cases, the prosecution usually focuses on the blood result rather than proving that your driving was visibly impaired.
There is also a separate offence of driving while unfit through drugs. That type of allegation may involve evidence about your driving, police observations, field impairment tests and medical or toxicology evidence.
Drug driving penalties
A conviction for drug driving can lead to a minimum 12-month driving ban, an unlimited fine, a criminal record and a DR80 endorsement. GOV.UK explains the main drug driving penalties, including a minimum one-year ban, an unlimited fine, up to six months in prison and a criminal record.
The exact outcome depends on the charge, the evidence, previous convictions, aggravating features and mitigation. If you want a fuller breakdown of bans, fines and criminal record impact, read our guide to drug driving penalties.
For a more detailed explanation of how courts approach sentence, see our guide to drug driving sentencing guidelines. The Sentencing Council guideline for driving with a specified drug above the specified limit explains how courts assess culpability, harm and sentence.
Roadside drug tests and blood samples
A roadside drug test is usually only the first stage. If the police suspect drug driving, they may arrest you and request an evidential blood sample at the police station.
The blood result is often central to the case. Important issues can include the timing of the sample, the chain of custody, laboratory analysis, continuity evidence and whether the result is above the legal limit for the drug alleged.
If there are problems with the sample, the paperwork or the way the evidence was handled, those issues may need to be raised before court.
Prescription medication and drug driving
Some drug driving cases involve prescribed medication such as diazepam, morphine, methadone, codeine or other controlled drugs. Having a prescription does not automatically prevent a prosecution, but it may be highly relevant.
A medical defence may be available where the medication was prescribed or supplied for medical or dental purposes and taken in accordance with medical advice. The CPS drink and drug driving guidance explains that the medical defence must be disproved by the prosecution if it is properly raised. The court will look closely at the prescription, dosage instructions, timing and your account of what happened.
If medication is involved, read our dedicated guide to drug driving and prescription medication before deciding how to plead.
Cannabis drug driving cases
Cannabis drug driving cases usually involve THC and a laboratory blood result. A driver may be charged even if they did not feel impaired at the time of driving.
The evidence may need to be reviewed carefully, especially where there are issues around timing, roadside testing, blood sample procedure or medical cannabis.
For more detail, read our page on cannabis drug driving solicitors.
Cocaine drug driving cases
Cocaine drug driving cases may involve cocaine or benzoylecgonine, also known as BZE. These cases can be complex because the blood result, timing, breakdown products and laboratory evidence may all matter.
The prosecution evidence should be reviewed before you decide whether to plead guilty or not guilty.
For more detail, read our page on cocaine drug driving solicitors.
Can a drug driving charge be defended?
Some drug driving cases can be defended. The right approach depends on the evidence.
Possible issues may include:
- Whether the police had a lawful basis for the stop and test
- Whether the roadside test was carried out properly
- Whether the blood sample was taken correctly
- Whether the sample was stored and analysed correctly
- Whether continuity can be proved
- Whether prescription medication is relevant
- Whether the laboratory result is reliable
- Whether the prosecution can prove you were driving
- Whether a medical defence may apply
A solicitor can review the evidence and advise whether the case can be challenged or whether mitigation is the better route.
What if you failed to provide a blood sample?
Failing to provide a specimen is a separate offence and can carry serious penalties. In some cases, there may be a reasonable excuse for not providing a sample, but this depends on the evidence.
If you are accused of refusing or failing to provide a specimen, read our page on failing to provide a specimen before your court hearing.
Should you plead guilty or not guilty?
You should not enter a plea until you understand the evidence against you. A guilty plea may be appropriate in some cases, but in others the evidence may need to be challenged.
Before deciding, you should know:
- What drug was alleged
- What the blood result says
- Whether the result is above the specified limit
- Whether prescription medication is involved
- Whether police procedure was followed
- Whether the sample continuity is clear
- Whether there is a defence or medical argument
- What sentence is likely if you plead guilty
Scarsdale Solicitors can review the evidence and advise on plea, mitigation and representation.
