Should you take a stranger to their driving test? The risk, the money, and the real answer
Here is a number that might surprise you: 83.4% of UK driving instructors receive requests from pupils they have never trained asking to be taken to a driving test. Not occasionally. Weekly.
That figure comes from the DVSA's own Working as a Driving Instructor Survey, October 2025, based on 3,448 ADI responses. It is the most widely reported challenge in the industry after the test backlog itself — and yet it barely gets discussed in terms of what the decision actually involves.
63.1% of ADIs say they never accept these requests. 26% rarely accept them. 9.9% sometimes. The small remainder accept them regularly or always.
The question is whether the majority is right, why the minority thinks it's worth it, and — most importantly — what the actual exposure is if you say yes and something goes wrong.
Why this is happening
The test backlog is the proximate cause. As of late 2025, the average learner wait for a practical test was 22 weeks, with 70% of test centres at the 24-week cap. DVSA itself acknowledges the backlog will not normalise until late 2027 at the earliest.
When pupils finally get a test date after months of waiting, the slot is often at a time or location that doesn't work for their usual instructor. Their ADI might be on holiday, ill, semi-retired, or simply unavailable on that particular morning. The pupil is not going to give up a test date they waited five months for. So they go looking for someone — anyone — with a dual-control car and an ADI badge.
The DVSA booking rule changes of May 2026 have added another layer. Instructors can no longer book or manage test slots directly through OBS. Pupils must book in their own name. One side effect is that some pupils booked tests during a period when they had an instructor, then lost that instructor (moved, retired, changed schools), and are now test-ready with no ADI to accompany them.
On paper, it looks like a gap in the market. In practice, the question is who bears the cost when the gap closes badly.
What "a stranger" actually means
Before the risk analysis, it's worth being precise about what we're actually talking about. When an instructor receives a stranger-to-test request, the pupil is almost always presenting themselves as ready. They'll say they've had 40 hours of lessons. They'll say their previous instructor said they were good to go. They'll say they just need someone with a dual-control car.
What you don't know:
- Whether any of that is true
- What standard they actually drive to
- Whether their previous instructor assessed them as ready for test, or ready for more practice
- Whether they have specific weaknesses their previous instructor was working on
- Whether they passed their theory test recently (it's valid for 2 years, but knowledge fades)
- Whether they've driven at all in the weeks since their last lesson
In short: you don't know what you're putting forward. And as the accompanying ADI, the car, the assessment, and the professional association are yours.
The money argument examined
The appeal is obvious. A pre-test hour plus test centre waiting time is typically 2.5 to 3 hours of your day. At £38-40 per hour, some ADIs charge £80-100 for the pre-test lesson and a flat waiting fee of £40-60. Call it £120-160 for the morning.
That is real money. For a half-day of work, it is not far off what a regular morning's teaching would bring. And if the pupil passes, they leave happy, there's nothing for anyone to complain about, and you've filled a slot that might have otherwise sat empty.
The problem is the comparison is false. When you teach your own pupil, you know what they can and cannot do. You know when to ask the examiner for more time. You know whether they parallel park consistently or whether it's their Achilles heel. You know their nerves, their bad days, and what they need to hear before a test to perform at their best.
With a stranger, you have none of this. You're accompanying someone you met an hour ago into a formal DVSA assessment. And if that assessment goes badly, the consequences for you are not symmetric with the £120-160 you were paid.
What you are actually risking
Your car and insurance
If the pupil is involved in a collision during the test — whether their fault or not — it's your vehicle. Your ADI insurance covers you for driving tuition. The question is whether "driving tuition" covers a formal test accompanying trip for a pupil you've spent one hour with.
Most ADI insurance policies cover test accompaniment. But read the wording carefully. Some policies require the pupil to be "your pupil" — meaning someone you've been training over a period of time, not a one-off test accompaniment. A collision with a stranger-pupil could result in your insurer arguing that the trip doesn't fall within your cover, leaving you personally liable for vehicle damage, third-party claims, and legal costs.
Before you accept a stranger-to-test request, call your insurer or read your policy. This is not a hypothetical concern — it is a live coverage question that the wording of your specific policy will answer.
Your ADI registration
DVSA's standards check system is trigger-based, and pass rate anomalies are among the factors that can trigger a check. If you start taking strangers to tests in volume and a pattern of failures emerges, the question DVSA's system asks is: why does this instructor have an unusual failure pattern?
That question leads to a standards check. A standards check where the examiner observes you teaching someone you have a very thin relationship with is unlikely to reflect well on the quality of your client-centred instruction, lesson planning, or use of the DVSA's competency-based assessment framework.
Beyond the pass rate question, DVSA has the power to investigate ADI conduct generally. The ADI Code of Conduct (part of the ADI register framework) includes professional conduct and not acting in ways that bring the profession into disrepute. An instructor who routinely takes under-prepared strangers to tests may find that DVSA considers this inconsistent with holding an ADI licence.
The declaration problem
DVSA's test booking system requires the accompanying ADI to confirm their details as the instructor. If you sign that declaration as a stranger-pupil's "instructor" having spent one hour with them, you are making a representation to DVSA about your relationship that may not be accurate in the way the system intends.
This is a greyish area. There is no specific law saying you cannot accompany someone to a test as a one-off. But falsely representing the nature of your relationship with a pupil to DVSA is not a position you want to be in if anything goes wrong and DVSA are reviewing your conduct.
The complaint risk
A pupil who fails their test after you accompanied them has someone to blame. If they paid you, they may believe you were implicitly guaranteeing their readiness or at minimum taking some responsibility for their outcome. A bad review, a DVSA complaint, or a Trading Standards report for misrepresentation are all realistic outcomes from a pupil who paid good money, waited five months for a test date, failed, and is looking for someone to be angry at.
Your own regular pupils don't typically complain when they fail, because the relationship is ongoing and they know the process. A stranger-pupil has none of that context. They met you an hour ago. They paid you. They failed. In their mind, you failed them.
The ethical argument
This one matters more than some ADIs acknowledge.
The driving test exists to assess whether a pupil is safe to drive unsupervised on UK roads. The examiner's decision is based on what they see during a 38-40 minute drive. The ADI's professional role — in theory and in the DVSA's own framework — is to present a pupil when the ADI, as the trained professional, believes the pupil is ready.
When you take a stranger to a test, you are short-circuiting that system. You don't know whether the pupil is ready. You're essentially providing transport and a dual-control car for someone else's assessment, without the professional judgement that is supposed to accompany it.
94.1% of ADIs cite high waiting times as the reason pupils take extended breaks. 30% of ADIs report that managing pupil expectations and readiness — convincing pupils not to push for premature tests — is one of their top challenges. The stranger-to-test phenomenon is the same pressure applied externally: a pupil who doesn't have an instructor to push back saying yes to someone who is willing to provide a vehicle without asking the harder question.
You don't have to carry the entire profession on your shoulders. But it's worth being honest that the widespread version of this practice — lots of ADIs taking strangers to tests at scale — would meaningfully undermine the system that your professional licence exists within.
When the answer might legitimately be different
The analysis above applies to the general case. There are narrower scenarios where taking a stranger to a test is defensible:
You do a proper assessment first. Some ADIs will take a stranger to a test, but only if they do a full mock test or assessment lesson beforehand (in addition to the pre-test) to form their own professional view of readiness. If after two hours with the pupil you genuinely believe they are test-ready, your judgement is closer to how you would assess your own pupil. This takes 3-4 hours of your time and should be priced accordingly — and you should still be clear with the pupil that you're forming your own independent view, not endorsing a previous instructor's.
You know the pupil's previous instructor and trust their judgement. If a colleague ADI calls you, explains they have a pupil who is genuinely ready, and asks if you can cover because they're ill, you have the basis for a professional judgement about the pupil's standard — mediated through a trusted professional peer. This is different from a stranger's self-reported "I've done 40 hours."
You have capacity and a transparent process. Some ADIs who do accept stranger-to-test requests are transparent about exactly what they are providing: test accompaniment, not endorsement of readiness. They are clear with the pupil that they are accompanying them to a test, not vouching for their standard. Whether this resolves the declaration concern is a matter of interpretation, but it's a cleaner position than implicitly presenting yourself as the pupil's instructor.
What to say when you decline
The default answer for most ADIs should be no. Here is a way to say it that is polite, complete, and closes the conversation:
"Thanks for getting in touch. My policy is only to accompany pupils I've personally trained to readiness — I'm not comfortable taking someone to test without knowing their standard. If your original instructor isn't available, it's worth contacting local ADIs directly or checking the DVSA's Find an instructor service to find someone who might have a pre-test slot. Good luck with the test."
This is not dismissive. It explains your reasoning briefly, and it offers a redirect. It does not invite negotiation or leave ambiguous space for "but what if I just explained my situation." It's a professional no, and it's the right default.
If you do accept — the minimum requirements
For the ADIs who decide that some stranger-to-test work fits within their practice — perhaps using the assessment approach described above — here is the minimum that should be in place before you proceed:
Check your insurance policy explicitly. Call your insurer and ask directly: "If I accompany a learner driver to their test and I have only spent X hours with them, am I covered for third-party liability and vehicle damage?" Get the answer in writing.
Conduct your own assessment. One pre-test hour is not enough. If you're putting your name to a test accompaniment, do enough teaching to form your own view of their standard. This means at least a mock test — ideally more.
Charge appropriately. Your time, your risk, your assessment. The "one hour pre-test + waiting" rate does not price in the additional exposure you're carrying. Price for the actual hours and the actual risk.
Be honest with the pupil about what you can and cannot know. "I've spent two hours with you and I believe you're driving at a standard that gives you a reasonable chance of passing. I cannot guarantee an outcome, and I'm accompanying you as a professional assessment, not as a guarantee." This sets expectations and reduces the complaint risk if they fail.
Keep records. Note the hours you spent with the pupil, your assessment of their standard, and the date. If DVSA ever asks, you want documentation showing you exercised professional judgement.
The year-end view
The pattern emerging from the DVSA data is that stranger-to-test requests are not going away. As long as the test backlog persists — and DVSA's own projections say it runs into late 2027 — there will be test-ready pupils who cannot locate their original ADI for test day. The requests will keep coming at a rate of two to three per week for most full-time instructors.
The sustainable professional response is a default no, with clear reasoning, applied consistently. The small percentage of ADIs who accept some of these requests carry higher risk and should price and structure their involvement accordingly. The ADIs who accept them casually — one pre-test hour, no insurance check, no meaningful assessment — are carrying exposure they may not have priced.
The £120 for a test morning looks attractive. It looks less attractive once you price in the tail risk on your insurance, your registration, and your reputation. The 63.1% who always say no are not leaving money on the table. They're pricing correctly.
The short version
83.4% of ADIs get stranger-to-test requests. 63.1% always say no, and they're right in the general case. The money is real but insufficient when measured against: potential insurance coverage gaps, the DVSA conduct framework, the declaration you're signing, and the complaint exposure from a test-day failure. The legitimate exceptions are narrower than they seem — they require your own assessment, a clear understanding of what your insurance actually covers, and honest communication with the pupil about what you can professionally vouch for. For everyone else: a polite no, a redirect to the DVSA find-an-instructor service, and a policy applied consistently.
