What's the biggest thing I'm legally allowed to drive?

[Phate]

Morning all,

As title, what's the biggest thing I'm allowed to drive? For example, theres a single car transporter here (standard 5 speed gearbox) - Would I be legally allowed to drive that on a Standard UK License?

Can provide pictures of said car transporter if required.

Thanks
