Off topic, and not your fault, but that is an explanation that isn't
entirely free from ambiguity and illogic.

The unladen weight excludes passengers but includes items needed for
ordinary operation.  Is
the driver a passenger or an item needed for ordinary operation?  Or both?
Or neither?

It doesn't include the weight of batteries in an electric vehicle.  I can
understand excluding
fuel, since a petrol/diesel/hydrogen vehicle may be operated with a tank
that's nearly empty
but batteries are a dead weight as much as the chassis is.  What would be
far more sensible
and consistent with the exclusion of fuel would be to include the batteries
(items needed for
ordinary operation) but to exclude the almost infinitesimally-small extra
mass created by charging
the batteries (subtle point of physics: energy, of any kind, has mass).

The law is an ass.  A simplified explanation of the law is a bigger ass.
