Can I drive someone else's car on my own insurance?

Only if your policy includes a Driving Other Cars extension and its conditions are met, including any condition about which cars are included. The extension usually applies to the policyholder rather than to named drivers on your policy. Check your policy wording, or ask your insurer to confirm.

Does a Driving Other Cars extension cover damage to the car I borrow?

It depends on the extension. Some provide third-party cover only, which does not cover damage to the borrowed car. Some provide comprehensive cover, subject to conditions. Having comprehensive insurance on your own car does not by itself confirm that the borrowed car is covered for damage.

What is the difference between open driving and being a named driver?

Both work through the policy covering the car being driven. Open driving allows other drivers who meet the insurer's conditions to drive the car with permission. A named driver is a specific person added to the policy and declared to the insurer. In both cases the cover is whatever that policy provides.

If I crash someone else's car, whose insurance is affected?

It depends which arrangement applied. Under your own Driving Other Cars extension it is your policy. Under open driving or as a named driver it is the policy covering that car. Whether a no-claims bonus is reduced depends on the policy, the circumstances and whether bonus protection was bought. Both the driver and the policyholder should follow their own insurer's reporting requirements.

Which cars can I not drive on a Driving Other Cars extension?

Conditions vary by policy. Depending on the policy, exclusions may apply to cars owned by you, your spouse or partner, or your employer, and to hired, leased or hire-purchase vehicles. Check the exact ownership, finance and vehicle-value conditions on your own policy.

Can I Drive Someone Else's Car in Ireland? Insurance Explained

30 March, 2021 Updated 29 September, 2026

The short answer is that you are only insured to drive someone else’s car if cover applies to you, driving that particular car. Their permission is not insurance. Three different arrangements can provide that cover, they work in different ways, and which one applies changes what happens if something goes wrong.

The three arrangements, and how they differ

People use these terms interchangeably. They are not the same thing.

	Driving Other Cars extension	Open driving	Named driver
Whose policy provides the cover	Your own policy – it travels with you	The policy covering the borrowed car	The policy covering the borrowed car
Who qualifies	Usually the policyholder only, not named drivers on your policy. Conditions apply to the driver and to which cars are included	Drivers who meet that insurer’s conditions, driving with permission	The specific people named on that policy, declared and accepted
Damage to the borrowed car	Only where the extension provides comprehensive cover. Some provide third-party cover only	Whatever that policy provides	Whatever that policy provides
Which policy a claim could affect	Yours	The one covering the borrowed car	The one covering the borrowed car

That last row matters more than people expect. If you borrow a car under open driving or as a named driver, it is the policy covering that car which responds, and the renewal on that policy which may be affected. Whether a no-claims bonus is reduced depends on the policy, the circumstances of the claim and whether bonus protection was bought. The CCPC notes that a bonus can be reduced on a step-back scale rather than lost outright, and that it may be restored if the insurer recovers its costs from another party.

Whichever arrangement applies, both the driver and the policyholder should follow their own insurer’s reporting requirements after an incident. Do not assume that only the person whose policy pays needs to report it.

Before you borrow someone’s car

Ask which arrangement applies. Are you covered by your own Driving Other Cars extension, by open driving on the policy covering that car, or as a named driver? The answer decides everything else.
Check the conditions, not just the heading. Insurers set their own. Look at the driver, licence, age and vehicle conditions on the policy in question.
Check whether that particular car is included. Depending on the policy, exclusions may apply to cars owned by you, your spouse or partner, or your employer, and to hired, leased or hire-purchase vehicles. Check the exact ownership, finance and vehicle-value conditions.
Check the car is taxed and displaying a current insurance disc. Citizens Information notes a current disc must be displayed whenever the vehicle is driven. Do not rely on the displayed insurance disc alone: confirm that the insurance remains in force and that you are covered to drive the car.
If you are unsure, get it confirmed. Ask your insurer or GMIB.ie to confirm whether you are covered to drive the particular car and what that cover includes. Request written confirmation and keep it with your policy documents.

Is damage to the borrowed car covered?

This is worth separating out, because the answer depends entirely on which arrangement applies.

Under your own Driving Other Cars extension. A Driving Other Cars extension may provide third-party cover only, which does not cover damage to the car you borrow. Some policies provide comprehensive Driving Other Cars cover, subject to conditions. Having comprehensive insurance on your own car does not, by itself, confirm that the borrowed car is covered for damage – the extension is a separate benefit with its own terms.

For example, if you reverse a borrowed car into someone else’s wall, third-party-only cover may cover your liability for damage to the wall, subject to the policy terms. It does not cover repairs to the borrowed car.

Under open driving, or as a named driver. The cover is whatever the policy on that car provides. If it is comprehensive, that generally extends to you; if it is third party only, there is nothing there to repair the car. The CCPC describes a named driver as someone added to a policy who is then covered under it.

Common situations

Borrowing a parent’s car. Explain to the insurer who will drive the car and how it will be used. Ask whether the existing cover allows your use or whether you need to be added to the policy. If you will be the main driver, make that clear – being listed as an additional named driver is not a substitute for correctly identifying the main driver.

Driving a partner’s car. Do not assume a Driving Other Cars extension covers it. Depending on the policy, exclusions may apply to cars owned by a spouse or partner, so this is a condition worth checking before you drive rather than after.

Borrowing a friend’s car for one journey. Check whether you hold the extension and whether that car’s policy includes open driving. Either can work. Neither is automatic, and your friend’s permission is not itself cover.

What to ask

Do I have a Driving Other Cars extension, and is it third party only or comprehensive?
Does it cover this particular car, given who owns it and how it is held?
Does the policy on that car include open driving, and what does it require of the driver?
If something happens, which policy responds, and what is the excess?
What does each of us need to report to our own insurer afterwards?

If the wording is not clear, ask before you drive rather than after. Call us on 0818 92 92 42, Monday to Friday, 9am to 5.30pm.
