With some road trains almost 60 metres long, new rules in WA mean truckies will have to display signs alerting other drivers to their vehicles' length. But the haulage industry says the change will be costly and ineffective.

I like the idea at the end of the article more. Spend some time educating people on how to overtake roadtrains safely. Me, i have no ideaif the random bits i’ve been told would actually be useful or not.
