As previously mentioned on a sunny day I will watch the shadow but I don’t fully rely on that because it still looks too close when it first clears. I mainly judge by the distance in the mirror. A good mirror makes a big difference as well; IMHO. I also use a small round mirror for a quick side view in the blind spots. Once I feel that I have some distance between us I will move over, remaining very careful of other cars that may be darting out and around you. Some people just can’t stand to be behind any kind of a truck or trailer at all and will dart around them quickly, even on the right side. I also try and give a good warning with my signal light as well as to what my intention is. With more experience it becomes easier and you know more what to watch for.
