Drivers could be caught out on their car insurance premiums over what they post on social media sites, it has been claimed.

Insurance heavyweight Admiral is set to analyse words used on Facebook accounts of first-time car buyers to see whether their personalities suggest they will be safe drivers.

The service is called firstcarquote and will look at a variety of traits, such as how well organised someone is by looking at whether they use times and locations when arranging to meet others.

It will also analyse sentence length and structure and use of words, but will not be able to look at photos.
