> Far be it from me to say a driver can't listen to music while they are at work.

If they're listening at a volume where it isn't noticed by / bothering other people, then there's no problem. Otherwise, it's noise pollution. Trucks are too loud as it is, we don't need even more noise thrown into the mix. Whether it's people playing music through their phone speakers on a city bus, or a guy reving his unmuffled motorcycle at 4:30 in the morning every day, or somebody blasting heavy bass music through their car or truck speakers when they slowly cruise through through your neighborhood, it's all assholish behavior.
