Quick checklist
Start with these
Start With The Charge And Specimen Request
The first documents should show what has been charged, when the case is listed, what specimen was required and where the requirement was made. Distinguish roadside preliminary tests from evidential specimens at a police station or hospital.
GOV.UK explains that refusing or failing to supply a sample without a reasonable excuse can lead to arrest. Do not rely on a general explanation without the police and medical records.
- Charge sheet, summons, requisition or single justice procedure notice.
- Court date, venue, hearing type and any bail conditions.
- Custody record, MG DD forms, breath-test printouts or hospital documents if available.
- Body-worn video, CCTV, interview or officer-statement references.
- Details of the warning given and the specimen requested.
Medical, Reasonable-Excuse And Mitigation Material
If the issue is physical inability, panic, needle phobia, breathing difficulty, medical treatment or misunderstanding, gather documents that show the condition, timing and effect on the ability to provide the requested specimen.
Mitigation is separate from whether the offence is proved. If sentence advice is needed, include driving history, work impact, caring responsibilities, treatment steps and any relevant previous convictions.
- GP, hospital, mental-health or medication records relied on.
- Witness notes from anyone present before, during or after arrest.
- Driving record, previous convictions and current licence position.
- Employment, caring, treatment or rehabilitation evidence where relevant.
- A short chronology from stop or incident to charge.
Scope The Motoring Barrister Request
A barrister may advise on plea, evidence, reasonable-excuse issues, sentencing, mitigation or representation at a suitable magistrates court hearing.
Some cases need solicitor support, especially where evidence must be requested urgently, expert medical evidence is needed, trial preparation is complex, or continuing litigation conduct is required.
Source note: source-checked against GOV.UK drink-driving penalties, GOV.UK police-stop breath-test guidance and the Sentencing Council guideline on 17 September 2026. Reasonable excuse, medical evidence, plea, sentencing, special reasons and disqualification issues need specialist motoring barrister or compliance review before publication.

Failure To Provide Specimen Barrister Evidence Guide FAQs
What evidence matters in a failure to provide specimen case?
Send the charge, court date, police paperwork, details of the specimen requested, warnings given, medical or mental-health evidence relied on and any video or custody-record references.
Can a medical issue be relevant?
It may be relevant where a reasonable-excuse issue is raised, but medical and causation evidence must be reviewed carefully on the facts.
Can a barrister guarantee no ban?
No. The court decides outcome and sentence. A barrister may advise or represent where arguments are properly available on the evidence.
