Normally cars have to be really careful around horses, but if they spot Cracker coming, they better get out of the way.
The 16-year-old shire is the tallest horse in Britain, and from the floor to the top of his ears is as big as a bus.
Measured in hands from the ground to the horse's shoulder, which is the proper way to work out how tall a horse is, Cracker is 19.5 hands high.
He weighs a whopping 190 stone and gulps down 35 gallons of water every single day to keep him refreshed.
His owner, Keith Sanders, told The Sun newspaper: "He's a lovely, gentle animal."
