Q422: I am going to buy a car at an auction, can I drive it home and then take out insurance?
No, before you drive any motor vehicle on a public road you must have valid insurance. Many providers offer temporary or short-term car insurance which would cover you for circumstances such as this.
You must not drive a motor vehicle until you have insurance.
If you drive an uninsured vehicle on the road you could be prosecuted and your vehicle could be seized.
