Don't drive like a fanny, listen to your Granny.

Research showed that young guys are better drivers when they have a female relative in their car. So who better than Gran to tell them to slow down, stop texting and stay off the 'toot' when behind the wheel.

A series of humour videos, posters, social posts and even a real life granny in a pub were enlisted to get through to young men when they're driving.
