http://7sage.com/lsat_explanations/lsat-20-section-4-question-03/Hi! Please find below the way I solved the question:
Opponents Conclusion: triple trailer trucks (ttt) are more dangerous than other commercial vehicles
Premise: Where ttt are permitted, for these vehicles the rate of road accident fatalities per mile is lower than the national rate for other commercial vehicles
Conclusion: ttt are safer than other commerical vehicles
A) Irrelevant
Provides an alternate explanation for why the rate of accident fatalities is lower, thus, weakens
C) So what if they oppose everything
D) In some way supports our argument as it says they require a special license thus even safer drivers drive ttt
E) Irrelevant fact
Is my trail of thought correct?
Thanks for your help!

The only thing I would say is that having a special license doesn't necessarily mean that the drivers are safer. The special license could just be the product of paying yearly dues or something else totally unrelated to driving competency.
