I'm not sure Switzerland share the European laws about cars/trucks being not in the EC,but
they have a slightly different different approach I think...I'm 20 mins far from the border and have a good mate
who runs a Toy-ouch!-ta,so can ask details if needed.
About Italy (and UK if some mate from the old island appears to confirm) bullbars are actually banned,
foam filled ones have been introduced as a general (IMHO) view seem to be 4x4s are evil,they're too big,too heavy,too dangerous etc (see:pollution threads etc),so laws are getting more restrictive.
As I already wrote somewhere I'm not allowed to fit bigger tires (must stay within a +5% starting from the OE tires...205/80R16 I had...),have to pay 30 or more euros to get the permission,have to drive the truck for the local "MOT" test and on and on.
Same applies for everything else.
Bullbars were allowed until a certain MY but can't remember now.
My logbook says I'm allowed to fit one,but I should have it tested and registered and here we go again...
Mmmh,gone a bit OT,should someone need more infos about Swiss laws PM me or ask here,I'll give my friend a yell and report.
Hope it helps.
(BTW,dunno what's the weather like over there,but I was fitting my winch almost in T-shirt this afternoon...)
(obviously I'll have to pay soon in Jan for that and have it checked out)
