I thought, probably mistakenly, that most big rig truckers used Qualcomm or the like which inherently is a tracking/locator device or is that just big logistics firms like Weiner, JB Hunt, etc?
Yes. I work for a hazmat company and we have Omni-trac. It gives the company all my info in real time. It is coupled with a dash cam. It constantly verbally tells me to slow down, watch my distance, etc. I constantly curse it out. It reads speed limit signs from side roads, etc, and has errors all the time.
