That's interesting. Things are indeed changing rapidly these days with new technologies in the trucks, new laws on the highways, and new tracking systems by the government like CSA 2010
http://www.bigrigdriving.com/comprehensive-safety-analysis-2010-csa2010. There's a lot of information available on the internet but it comes from a lot of different sources and can take a good amount of time to try to keep up with.
This might raise some alarms with drivers, but I wonder if some sort of mandatory schooling be put in place to help drivers track important changes in the industry. Maybe the government could come up with online computer-based training programs that need to be taken every so often (every two years maybe?) to show that drivers are aware of and understand the most current laws in the industry?
Things have never changed more quickly in the industry than they have in the past few years. It is indeed hard to keep up with.
