Are Heavy-Duty Trucks the Key to Solving Air Pollution?

I wrote this blog post for Geotab, a telematics company that specializes in fleet management. Its impetus was a recent study that showed that heavy-duty truck emissions were far more dangerous than car emissions. I really enjoyed writing this one, because it forced me to examine my own opinions on this environmental issue and opened my mind to other data and therefore a different solution than what I thought was right.
