If I Have Fully Comprehensive Car Insurance Can I Drive Any Car? UK Guide to DOC Cover, Exclusions, How to Check, Penalties & Safer Options
You’re not alone if you’ve googled If I have fully comprehensive car insurance can i drive any car, it sounds like comprehensive should mean any car, any time. In the UK, it usually doesn’t.
The real answer depends on whether your policy includes a specific permission called Driving Other Cars (DOC), what your certificate says, and a handful of common exclusions.
If I Have Fully Comprehensive Car Insurance Can I Drive Any Car in the UK?
No, fully comprehensive cover is primarily about the car you’ve insured and the drivers listed on that policy, not a universal pass to drive whatever you like. If you drive another car without the right cover in place, you can still be treated as uninsured.
Why comprehensive doesn’t automatically cover any car?
In UK insurance, there are two separate ideas:
- Cover on a specific vehicle (your insured car), and
- Permissions for you as the policyholder, like DOC, if included.
Car-based cover vs driver-based permissions: what insurers mean in practice?
Most of the time:
- Your main policy covers your car to the level you bought (comprehensive / TPFT / TPO).
- DOC (if you have it) is an extra permission with stricter rules and often lower cover.

What Driving Other Cars (DOC) cover is and why it matters?
DOC is a clause on some comprehensive policies that may let the policyholder drive a car they don’t own, with permission, without being named on the owner’s policy.
DOC is not guaranteed and is often removed or restricted
DOC used to be more common. Now, many insurers restrict it or don’t include it by default. So you can’t assume it’s there just because you’re fully comp.
DOC is usually third-party only what that covers and what it doesn’t
This is the big gotcha: When DOC exists, it’s commonly limited to third-party only.
That means it may cover:
-
Injury or damage you cause to other people and their property
But it may not cover:
- Repairs to the borrowed car.
- Theft of the borrowed car.
- Damage to the borrowed car if you scrape it, reverse into something, or have an at-fault accident.
So even if you’re insured to drive it under DOC, you might still end up personally paying for the damage to the vehicle you borrowed.
DOC is typically for occasional/emergency use
DOC is generally designed for occasional, short-term situations, not a workaround to drive multiple cars regularly without being added to the policy.

The most common DOC rules and exclusions UK drivers get caught out by
Policyholder-only vs named drivers (who DOC applies to)
DOC is often policyholder-only. If you’re a named driver on someone else’s policy (or someone is a named driver on yours), they may not get DOC at all.
Age limits and driver criteria
Many policies apply an age threshold (often 25+) and may restrict DOC based on driving history, convictions, or claims.
You must have permission
DOC usually requires the owner’s express permission. If you take a car without clear permission, you could be uninsured and risk additional legal trouble.
The other car may need its own insurance already
A common condition is that the other vehicle must already have its own insurance policy in place. If it doesn’t, your DOC may not apply.
Vans and non-standard vehicles
DOC commonly excludes:
- Vans / commercial vehicles
- Motor trade vehicles
- Sometimes motorbikes or unusual vehicle types
So if your plan is I’m fully comp, I can borrow a van for the tip, this is exactly where people get caught out.

How to check if you’re actually insured to drive another car?
Here’s what you can do next before you pick up the keys:
- Check your Certificate of Motor Insurance and/or policy schedule for wording about “Driving Other Cars” (DOC).
- Confirm whether it applies to you as the policyholder only or also to named drivers.
- Check whether it’s limited to third-party only.
- Look for exclusions like vans, hire/lease vehicles, cars you own, and whether the other car must already be insured.
- If it’s still not crystal-clear, call your insurer and ask them to confirm your cover.
If DOC isn’t clearly stated in your documents, don’t assume it exists.
What happens if you drive without the right cover?
UK legal penalties
Driving without valid insurance can lead to:
- A fixed penalty (commonly £300) and 6 penalty points.
- The chance of your case going to court (where penalties can be more severe).
- The vehicle being seized in some circumstances.
Even if you genuinely thought you were covered, that doesn’t automatically protect you if your policy doesn’t actually allow it.
Accident scenarios: who pays for what?
If you crash a borrowed car and you only have DOC (third-party only), the painful outcome is often:
- Third-party damages may be covered (depending on the terms).
- Damage to the borrowed car may not be covered.
- You could end up paying the borrowed car’s repair bill (or the owner’s insurer may pursue costs).
Risk to the owner: causing or permitting
If the owner knowingly lets someone drive their vehicle without proper insurance, the owner may also face consequences for allowing uninsured use. This is why some people will (rightly) ask you to prove cover before handing over keys.

Real-world scenarios
Can you drive your partner’s/parents’/friend’s car?
Sometimes, if DOC exists, and you meet the conditions. In practice, for anything beyond a one-off, being added as a named driver is often simpler and safer.
Courtesy car while yours is in the garage
Don’t assume DOC applies. Courtesy cars usually come with their own arrangement (via the garage or insurer). Always check the paperwork provided with the courtesy car.
Hire car on your own comprehensive policy
Often, hire cars are insured through the rental company and/or via add-ons. Many policies don’t treat hired cars the same way as privately owned vehicles for DOC purposes. If you’re hiring a car, treat it as its own insurance decision.
Test-driving a car privately
The safest route is either:
- The seller’s insurance explicitly allows your test drive, or
- You take out temporary insurance in your name for that car
If there’s any doubt, don’t risk it.
Moving house / borrowing a van
Assume DOC won’t cover a van unless your documents explicitly say it does. Temporary van insurance or being named on the van’s policy is usually the best option.
Safer alternatives to DOC: when you need proper protection?
| Option | When it’s best | Why it’s safer |
|---|---|---|
| DOC (if included) | Rare, one-off borrowing | Often legally valid for occasional use, but usually third-party only |
| Named driver | You’ll drive the car semi-regularly | More reliable cover that usually matches that vehicle’s policy |
| Temporary insurance | Short-term need (hours/days) | Clear, time-limited cover in your name for that specific car |
| Multi-car policy | Household shares multiple cars | Can be cost-effective and reduces confusion about who can drive what |
Here’s what you can do next:
- Need to borrow a car today? If DOC isn’t clearly written in your certificate, go with a temporary cover.
- Borrowing regularly? Become a named driver and avoid the grey areas.
Common DOC exclusions to check
| Exclusion to look for | Why it matters |
|---|---|
| Policyholder only | Named drivers may not be covered to drive other cars |
| Age limit (often 25+) | DOC may not apply at all if you’re under the threshold |
| Vans/commercial vehicles | DOC frequently excludes them |
| Hire/lease/finance | Borrowed cars under hire/finance arrangements may be excluded |
| Other car must be insured | DOC may only apply if the other car already has its own policy |

Conclusion
So, if i have fully comprehensive car insurance can i drive any car in the UK? Only if your policy explicitly includes DOC (or similar permission) and you meet all conditions.
And even then, it’s usually third-party only, with common exclusions like age limits, vans, hire cars, and requirements that the other car is already insured.
FAQs
Does fully comprehensive car insurance cover you to drive any car?
Not automatically. You can only do this if your policy documents explicitly include DOC (or another extension that allows it).
Is DOC cover always third-party only?
Very often, yes. That’s why borrowing a car under DOC can still leave you exposed to repair costs for the borrowed vehicle.
Do I need the other car to be insured already?
Often, yes. Many policies only allow DOC if the other car already has its own insurance policy.
How do I prove I’m insured to drive another car?
Your Certificate of Motor Insurance is the key document. If DOC isn’t stated there (or in your policy wording), don’t assume you’re covered.
Can I drive another car if I’m under 25?
Many policies restrict DOC to 25+. If you’re under 25, being added as a named driver or buying temporary insurance is usually the more realistic option.
