Normally in my line of work, i am not in need for squeezing out every minute from my allowed drive time. but you never know, so for many years now i learned how to take advantage of the 15 minutes increments of the paper log.
for example, if all possible, then i will start my line 3 or 4 about 6 minutes before a quarter of an hour.
that's allow me to "legally cheat" the paper log.
since i stop my truck at least once every 3 hours for a load check, by the end of the day i can add some valuable time to the allowed 11 hours.
