I remember driving from Landeck up to Nauders in Austria in a nearly new 318i auto sport box beemer back in the nineties and being overtaken by an Italian artic on one of the straights before a series of hairpin bends. The speed with which he approached us was scary, it was like one of those movies where the truck is intimidating a motorist in the rear view mirror!! He sure wasn't doing 56!!
> according to him its only British only built riggs that are fitted with restrictors <
Nonsense. In most western European countries these days a restrictor is obligatory. In any case in the Netherlands and Germany, and as far as I know in France too.
Another thing is that in a number of cases drivers know how to disable them, willing to take the risk to be found out. Enforcement differs per country.
Actually the cruise control in combination with the restrictor is one of the main reason that arctics/trucks often are a nuisance to caravanners.
The restrictor usually falls in at 90 kms/hr, taking into account that the max speed differs a bit per country and allowing for incidental overtaking.
Arctics/trucks usually set their cruise control drive a set speed on their restrictor and calculate the tolerance in enforcement. Hence they are often set to drive 86 to 90 km/h. The just want to continue at this fixed speed and just let the truck go at that speed. If caravanners stick to the rules they often are just a bit too slow for arctics and trucks and get overtaken a lot. Normally they should drive at around the same speed. This differs a bit per country, but in countries like the Netherlands and Germany this is a problem as caravanners mostly have to stick to the 80 km/h, while the arctics drive 90km/h. They get fined less than caravanners do.
