The laws on riding a motorbike trike in BG

Hi,
Any one know if the law is the same in BG as the uk, that you can ride a trike on your car licence without a helmet?
Has anyone also transported one from uk to BG?
Thanks

As the laws are E.U regarding bikes ect I do believe its the same as the Uk ..However even in the UK you cannot ride a Car based Trike on a motor cycle licence or a motorcycle based Trike on a car one..mental
Depends on the size of the trike maybe easier to fly back and ride it over in the summer..I know our bikes will be ridden over
