There are a lot of live webcams available for anyone wanting to see what some of the trucks are like in Canada.

I normally select the locations tab to get a list of cams and I find the Yellowhead Trail cams the most interesting.
Lots of road trains (double artics). Trucks mixing with the rest of the traffic with no lane or speed restrictions as per the UK.
