Anyone tried double towing in BC Canada?

Really? Have you ever towed doubles? It's not that complicated. Some people might have a little trouble backing up but even that isn't difficult to learn. I think requiring a special license would be understandable.... there probably are some who shouldn't be towing anything, but most who are skilled at towing a single trailer certainly should have no trouble learning to tow doubles.

An awful lot of goods are safely shipped across BC in Super B's. What is the logic behind allowing 145,000 lb semi trucks on the road with two trailers yet forbidding people wanting to tow a 40ft 5th wheel with a boat on behind?
