One eagle-eyed driver spotted the truck on Stanningley Bypass on Tuesday heading from the White Rose Shopping Centre towards its next destination in Pudsey.
The truck will be parked at the Asda Supercentre car park, in Owlcotes shopping centre, today.
Visitors can enjoy a glittering winter wonderland outside the truck and grab a free can of 150ml Coca-Cola zero sugar from 12pm to 7pm.
There will also be the chance to buy a pack of 250ml glass bottles of Coca-Cola personalised with your name.
This year, Coca-Cola is raising funds and awareness for homelessness charity Crisis by donating 10p in exchange for every can placed in recycling bins by the truck.
