Can I Drive Someone Else's Car? UK Insurance Rules Explained

It is one of the most common questions drivers ask, and one of the easiest to get wrong: can I drive someone else's car on my insurance? Plenty of people assume that holding fully comprehensive cover means they can jump into any vehicle and be insured. That belief has landed drivers with points, fines and an impounded car. The reality in the UK is far more limited, and it has tightened considerably in recent years.

This guide explains when you can drive another person's car, what your policy is likely to cover, the restrictions that catch people out, and the safer ways to borrow a car without risking your licence.

Can I drive someone else's car on my insurance? The short answer

In most cases, no, not automatically. Car insurance follows the car, not the driver. Your policy covers the specific vehicle named on it, which means it does not normally stretch to cars that belong to someone else. The only common exception is if your policy includes a feature called Driving Other Cars cover, usually shortened to DOC. Even then, the cover is far more limited than people expect, as we explain below.

What is driving other cars (DOC) cover?

Driving Other Cars cover is an optional extension found on some fully comprehensive policies. It gives you third party cover to drive a car that is not yours, with the owner's permission, usually for occasional or emergency use. Third party cover is the legal minimum needed to drive in the UK, so DOC lets you stay legal behind the wheel of a borrowed car, but it does no more than that.

It used to be a standard feature on most comprehensive policies. That is no longer the case. Insurers have steadily removed it, and only a small minority of comprehensive policies now include DOC as standard. For most drivers it has to be requested and added, often with an administration fee and a higher premium, and some insurers do not offer it at all.

Does comprehensive insurance cover driving other cars?

Not on its own. This is the single biggest misunderstanding around the topic. The word comprehensive describes the level of protection for your own car, covering damage to your vehicle as well as to others. It does not mean you are comprehensively covered to drive any car on the road. Without DOC listed on your policy, your comprehensive cover gives you nothing when you sit in someone else's car.

So the answer to "can I drive someone else's car with comprehensive insurance?" is only if your specific policy includes DOC, and only on a third party basis.

How to check whether you have DOC cover

Never assume. Check before you drive. The quickest way is to read your certificate of motor insurance and your policy booklet, where DOC will be spelled out if you have it. Look for a section often headed "driving other cars" or similar wording. If it is not mentioned, you almost certainly do not have it. If you are unsure, phone your insurer and ask them to confirm in writing. A two minute call is far cheaper than the consequences of getting it wrong.

The limits that catch people out

Even when you do have DOC cover, it comes wrapped in restrictions. These are the ones that most often trip drivers up:

• Third party only. DOC does not cover damage to the car you are borrowing. If you crash it, you pay for those repairs yourself, even if the accident was not your fault. It only pays for damage or injury you cause to other people and their property.
• The other car must already be insured. DOC does not insure an uninsured vehicle. The car you borrow needs its own valid policy in place.
• You need the owner's permission. Driving a car without the owner's consent is never covered, and can be a criminal matter in its own right.
• It usually only covers the policyholder. DOC normally applies to you as the main policyholder, not to other named drivers on your policy.
• Often restricted to emergencies or occasional use. Many policies limit DOC to social, domestic and pleasure use, not commuting or business, and expect it to be used now and then rather than as your everyday arrangement.
• Age limits apply. Most insurers require you to be at least 25 before they will offer DOC cover.

What if I only have third party insurance?

If your own policy is third party, or third party fire and theft rather than comprehensive, you almost certainly cannot drive other cars on it. DOC is a feature reserved for comprehensive policies, so lower levels of cover do not include it. In that situation you will need one of the alternatives below.

Safer ways to drive someone else's car

If you regularly need to drive a car that is not yours, DOC is rarely the right tool, since it only offers third party protection. Two options give you proper cover:

• Be added as a named driver. Ask the car's owner to add you to their policy as a named driver. You then share their level of cover, so if their policy is comprehensive, you are comprehensively covered on that car. Adding a driver can change the premium, sometimes up and occasionally down, but it is the cleanest way to be fully protected. If this leaves you on more than one policy, our guide on whether you can have two insurance policies on one car is worth a read.
• Take out temporary car insurance. Short term or temporary cover can be bought for as little as an hour and up to around a month. It suits one off trips, helping a friend move, or sharing the driving on a long journey, and it usually gives you comprehensive cover on the borrowed car for the period you choose.

Before you drive any car you do not own, it is also worth confirming it is taxed and insured in its own right. You can learn how in our guide on how to check if a car is insured.

What happens if you drive without the right cover?

The penalties for driving uninsured are serious and have got tougher. Get caught and you face six to eight penalty points and a fixed penalty fine of £300, or an unlimited fine and disqualification if the case goes to court. The police can also seize the vehicle on the spot and, in some cases, destroy it. Those points and the gap in your record then push up your insurance for years. The legal requirement to be insured is set out on GOV.UK.

Quick checklist before you borrow a car

• Check your own policy documents for DOC cover, or call your insurer to confirm.
• Remember DOC is third party only, so you would pay for any damage to the borrowed car yourself.
• Make sure the car has its own valid insurance.
• Get the owner's clear permission.
• If you need full protection, get added as a named driver or buy temporary cover instead.

Borrowing a car is rarely a problem as long as you check first. The trouble starts when drivers assume their comprehensive policy does more than it does. A quick look at your documents, or a short phone call, tells you exactly where you stand before you turn the key.
