The familiar "14-day rule" concerns the warning requirement for specified offences and is subject to statutory conditions and exceptions. It does not create a general right to ignore a driver-information requirement.
Direct answer
A NIP and a driver-information requirement do different jobs
A Notice of Intended Prosecution warns that prosecution for a specified allegation is being considered. A requirement under section 172 asks for driver information. A possible issue with the NIP does not normally permit the recipient to ignore the section 172 requirement.
| Document | Legal function | Immediate concern |
|---|---|---|
| Notice of Intended Prosecution | Warns of contemplated prosecution for an offence to which the statutory notice requirement applies. | Check the alleged offence, date, place, recipient and service history. |
| Section 172 requirement | Requires specified information about the identity of the driver. | Respond truthfully by the method and deadline stated on the notice. |
| Conditional offer or course invitation | Offers a possible disposal after the driver issue has been addressed. | Check eligibility, points, payment terms and the effect of acceptance. |
Where the driver is genuinely uncertain
Do not guess or nominate a person merely to complete the form. Preserve the notice and envelope, identify every possible driver, reconstruct the journey, and check diaries, messages, location records, payment records, fuel or parking transactions, work records and available camera material. Keep a dated record of the enquiries made. Whether the statutory defence is available is evidence-sensitive and cannot be assumed from an inability to remember.
| Document | Purpose | Immediate question |
|---|---|---|
| Notice of Intended Prosecution | Warns that prosecution for a specified allegation is being considered. | Was the statutory warning requirement met, or does an exception apply? |
| Section 172 requirement | Requires information identifying the driver or other information within the recipient's power to give. | Who received it, what information is requested and what deadline and method are stated? |
| Later offer or court document | Proposes disposal without trial or starts court proceedings. | What are the consequences of acceptance, plea or non-response? |
What to do first
- Record the allegation date, notice date and receipt date. Keep the envelope and any electronic transmission evidence.
- Identify the registered keeper at the relevant time. A later nominated driver may receive a notice after 14 days without that fact alone deciding the case.
- Answer the driver-information requirement honestly and by the stated method. Do not assume a potential NIP issue suspends that separate duty.
- If genuinely unable to identify the driver, investigate rather than guess. Check diaries, messages, location history, fuel or payment records, work records, photographs, telematics and possible drivers, and keep a dated record of the enquiries.
Frequently asked questions
Does a NIP received after 14 days end the case?
Not necessarily. The rule is offence-specific and subject to statutory conditions and exceptions. It may also be necessary to establish who the registered keeper was and when the first relevant notice was served.
Can I ignore the section 172 form while disputing the NIP?
No general rule permits that. Treat the information requirement as a separate obligation and obtain advice before its deadline if the position is disputed.
Should I name the most likely driver?
Do not make a nomination you do not honestly believe to be true. Where identity is genuinely uncertain, carry out and record reasonable, evidence-based enquiries.
