Better check labor laws, an employer is responsible for employee hours, if you are controlling their time, and this includes to and from job sites, if I get hurt driving to a job site I can collect worker comp, and I did when I was hit head on by another car, this includes over time on 40, this is very confusing and gets abused all the time, I have had employers who didn't pay drive time to jobs miles away, but in the end when a co-worker went to the labor board the company had to pay us back pay on all the time we did driving, not sure how it all works but it is on the DOL web site somewhere. the last company I worked for did pay driving time, and mileage on your vehicle if it was for going to a job site over a certain miles from the shop and it was necessary you took your own vehicle, but for the most part we would meet at the shop and go from their, but lets say they had a reason they needed to take their own vehicle like having an appointment they needed to get to right after work, then there mileage wasn't covered. just the driving time. of course they could take the vehicle anytime they wanted but they would only get mileage if it was required for a reason, other wise if there was a seat available in a truck going that way then they were supposed to ride to the job site.but still on company time.
