OK, I am going against the grain here: I have been around peripherally, (I prep the loads) heavy specialized loads for about 10 years now. We interface with the trucking industry. About two years ago when the talk really started in earnest, I asked a fellow how he felt about ELDs. He owns two trucks and hires 7-8 more trucks depending on the contract load needs and demands. He said that he got on board with ELDs as soon as they came out, he would not hire a truck without ELDs. They actually make better money for him and the contract drivers he uses. He gets more actual miles, no logbook infractions and DOT smiles benignly on him when they see him. Most of his work is in the midwest and west coast. Now, this may be an isolated case, but with all the double booking that goes on and gets caught, I would think honest drivers would prefer the level playing field.
It is the DOT cameras that get most people, they feed into a computer and within 2 minutes a scale can reel you in for a violation. I got reeled in driving a log truck part time, for out of date license tabs (by one day.) I got a finger wagging and while I was calling the boss to find out where the tabs were, the scale lady told me they had been bought, so get them on! DOT never caused me any fear, I tried to run right and when they did reel me in I had it coming, but I never had any real major violations, so it was always a finger wagging.
