So last week I had to change sleep schedules a few times because of the timing of the loads. I ended up having a 10hr break and was able to grab a full nights sleep but then a half hour into my drive I was told to take another 10hr break. Of course I couldn’t sleep again so soon so when that ended and my dispatcher sent me out with a new load I was dead tired a few hours into the route. I pulled into the next stop and called in to let them know I couldn’t make the window for the load.. He tried to get me to keep going but i felt unsafe driving being so tired so we were ended having a new driver take the load from me to make the window. It worked out but if the other driver hadn’t been so close it could’ve been different. Is this a common?
