DVLA Form B1 Explained: A Complete 2026 Guide
If you've been told after a head injury, brain scan, or neurological diagnosis that you need to “tell the DVLA”, you're probably trying to work out whether DVLA Form B1 is the right form, what it does, and whether it affects your licence straight away. That confusion is common because B1 is a medical reporting form, not a vehicle paperwork form. 
If you were looking for a driving or vehicle document form rather than a medical one, this guide to UK driving licence forms helps point you in the right direction before you spend time on the wrong paperwork.

What Is the DVLA B1 Form and Why Is It Important
The DVLA B1 form is the confidential medical report used by car and motorbike drivers who need to notify the DVLA about certain neurological conditions. GOV.UK distinguishes this from B1V, which is for lorry, bus and coach drivers, in its official B1V guidance.
That distinction matters because B1 isn't general admin. It's part of the DVLA's medical fitness to drive process. The driver reports the condition, the DVLA reviews the medical information, and then decides whether the licence can continue, needs renewal, or must be refused or revoked.
Practical rule: If a clinician has told you to notify DVLA after a neurological event, don't assume they're filing it for you. B1 is the driver's route into the licensing decision.
What B1 is not
B1 is not a logbook form, keeper change form, or replacement V5C form. It doesn't deal with ownership, registration, or vehicle records. It deals with whether a person remains medically fit to drive.
That's why people sometimes end up searching for the right letters but the wrong category of form.
Who Needs to Submit a DVLA B1 Form
The B1 form applies to drivers reporting specific neurological conditions. GOV.UK lists conditions including acute subdural haematoma, aneurysm, blood clots, brain injury, cerebral palsy, hydrocephalus, hypoxic brain damage, Lewy body dementia, subarachnoid haemorrhage and transient global amnesia in the official B1 form guidance.
In day-to-day terms, B1 usually comes up after a serious head injury, a neurological diagnosis, or hospital treatment that raises a question about driving safety. If the condition is on the DVLA list for B1, this is the form the driver uses to report it.
The responsibility sits with the driver
This is the part many people miss. Hospitals and GPs may advise you, but the legal duty to notify the DVLA is yours. That's especially important after discharge, when paperwork, medication changes, and recovery can make it easy to put driving admin to one side.
For readers trying to separate Group 1 and vocational forms, this overview of the D2 and D4 process can help clarify where medical and licence categories split.
Hospitals often explain the medical issue clearly. They don't always explain the paperwork clearly. That's where motorists get caught out.
How to Get and Submit the B1 Form
The safest route is to use the official GOV.UK medical form page for the correct B1 document. Because this is a medical declaration, accuracy matters more than speed. Fill it in carefully, make sure the condition details are complete, and follow the submission method shown on the official form guidance.
What usually works best
In practice, the drivers who avoid delay tend to do three things well:
- Use the correct form: B1 for car and motorbike drivers with the relevant neurological conditions.
- Complete every section clearly: Missing details can slow the case once the DVLA starts reviewing it.
- Keep copies: Save or photograph what you submit so you can refer back to it if DVLA asks follow-up questions.
A lot of confusion starts when motorists search broadly for “DVLA medical form” and land on the wrong document. If you're comparing licence application paperwork at the same time, this guide to the D1 form PDF download process shows how different standard driver forms are from a medical declaration like B1.
Before you send it
Check that the form matches your licence category. If you hold a lorry, bus, or coach licence, B1 is not the equivalent form. The vocational route is different.
What Happens After You Submit the B1 Form
Once the DVLA receives a complete B1 submission, NHS patient guidance says it normally aims to make a decision and contact the driver within about six weeks in the NHS brain injury advice leaflet. The same guidance says the DVLA may request a medical examination, GP or hospital information, or a practical driving assessment, which can extend the timeline.
That means the form itself is only the starting point. If the condition is straightforward and the information is complete, the process is usually cleaner. If the DVLA needs more evidence, the case can take longer while it gathers medical input.
Possible outcomes
The decision can go a few different ways. The licence may continue, it may continue with a shorter renewal cycle, or it may be refused or revoked depending on the medical position.
NHS guidance for head injury patients also warns that some drivers may be banned from driving for 6 months or more, and failing to declare a notifiable condition can lead to a fine of up to £1,000 as noted in the same NHS-linked guidance above.
A complete form helps. It doesn't guarantee a quick answer if the DVLA still needs evidence from doctors or wants an assessment.

Medical Forms vs Vehicle Forms Understanding the Difference
The differing purposes of Form B1 and Form V62 often cause searches to go off track. Form B1 is about medical fitness to drive. Form V62 is about applying for a V5C logbook. They sit in completely different parts of the DVLA system.
DVLA Form B1 vs V62 at a Glance
| Attribute | Form B1 | Form V62 |
|---|---|---|
| Main purpose | Report certain neurological conditions | Apply for a V5C logbook |
| What it affects | Your driving licence and medical review | Your vehicle record |
| Who usually uses it | Drivers with a relevant medical condition | Keepers missing a logbook |
| Typical trigger | Head injury, brain condition, related DVLA notification | Lost, damaged, or missing V5C |
| Outcome sought | DVLA fitness-to-drive decision | Replacement or obtained logbook |
If you're dealing with B1, you're answering a medical question about whether you can legally keep driving. If you're dealing with V62, you're sorting out paperwork for the vehicle itself. One is about the person. The other is about the car's registration record.
Where motorists get mixed up
A driver buys a used car without a logbook, or loses their V5C, and starts searching “DVLA form”. Another driver leaves hospital after a brain injury and searches “B1 DVLA form”. Both are looking for official paperwork, but the forms solve different problems.
That same form confusion shows up across the wider DVLA paperwork domain, including forms such as DVLA Form H1, which again serve a different purpose from B1.
If the issue is your health, think B1. If the issue is your logbook, think V62.
Frequently Asked Questions
Can I drive while the DVLA is deciding?
That depends on your medical situation and what advice you've been given. After a head injury, NHS guidance says some people may be banned from driving for 6 months or more while the formal decision is worked through in the University Hospitals Sussex patient leaflet. Don't assume that sending the form means you can keep driving as normal.
Do I need to tell my insurer as well?
Yes, that's a separate issue from notifying the DVLA. Insurance and licensing are not the same process, so don't treat B1 as the only notification you need to make.
What if my condition improves later?
If your medical position changes, the next step depends on the DVLA's decision on your case and the medical standards that apply to your condition. In practice, drivers usually need to follow the DVLA route for review or re-application rather than relying on informal medical reassurance alone.
If your issue turns out not to be medical at all, and you need a V5C logbook or need to complete a V62 without printing forms or posting a cheque yourself, CarForms.co.uk handles that separate process for you online. It's an independent service for motorists who need help replacing or obtaining a logbook, including the DVLA fee, form preparation, printing, postage, tracking, and confirmation.
