Mis-matched registration plates

[zetec]

Normally on European lorries, the cab unit having a different reg to the trailer. Last week on the M25 a Romanian registered cab was pulling a Latvian trailer for example. Is there different rules for Europeans as I see alot?

Trailers have their own registrations.
