Which V55/5 boxes can I leave blank?
Reviewed 2026-07-10
Short answer
Only leave a box blank when it genuinely does not apply or the official V355/5 guidance tells you not to complete it for your vehicle type.
Official position
The V55/5 is a generic form covering many vehicle types. DVLA guidance explains box-by-box requirements, and some boxes only apply to certain vehicle categories, approval routes or motor-trade cases.
What to do
Start with vehicle type: car, motorcycle, light goods, HGV, trailer or rebuilt vehicle.
Use your CoC, IVA/MSVA certificate, foreign registration document and MOT to fill technical fields.
Use the V355/5 guidance for boxes that do not apply to your vehicle category.
Explain missing approval data in the type-approval exemption area when appropriate.
Common mistakes
- Leaving technical boxes blank because the information is hard to find, not because it is inapplicable.
- Completing motor-trade boxes B1 and B2 as a private applicant.
- Copying another vehicle example where the approval route or tax class is different.
