Hi All,we are going to Spain via France in November and have some questions.1,is it ok to have reg plates with the GB sign on them instead of a stick on GB sticker,and does the car need to have the GB sign on both front and rear.2,is there a toll charge at the Dartford crossing if so any idea how much?we are only driving an vectra not towing.3 We will be enterring Spain from the Perpignan side so when we get to the spanish border will we be required to stop and show any documents etc?.4,is it acceptable to drive with clear light lenses or would it be better to change them to yellow?.I already know to change the beam angle for driving on the right.Many thanks,Kev & Christina.
