It might be an emergency or you may have permission from the car owner, but that doesn’t mean it’s legal. Unless you’re a ‘named driver’ on their car insurance, you almost certainly won’t be insured.
Can named drivers drive other cars?
If you drive someone else’s vehicle then you will not be covered by their (the main driver) motor insurance policy – you must become a named driver on their policy. As a named driver you will be given the same level of cover as the vehicle’s main driver.
Does the main driver have to be the policy holder?
The main driver (or vehicle policyholder) is the person who drives the vehicle most often and earns no claims discount. They do not need to be the principle policyholder but they must live at the same address as them.
Can you have 2 main drivers on car insurance?
You can’t take out a car insurance policy as joint policyholders with someone else – there’s no such thing as joint car insurance, even for married couples.
