8 days in 30 elogs

My take on it is if you go over 8 in any 30 you only need elog for that month. As you describe your operation you have to log the trip from your base to the job site then you can go 100 mile rule for each day you leave from and return to the job site in 12 or less hours (assuming you stay within 100 air mile radius). Then you would log the trip back home. These two trips have to be logged because you left from and returned to a different place on that particular tour of duty, even if the job was within the local radius.

Now, depending on what your industry is and if you cross state lines or not you may have more permissive intrastate hours of service rules and may not have to comply with the Federal rules. The elog rule only applies to interstate motor carriers (private and for-hire property or passenger) unless your state is one that adopts the Federal rules by reference, then your intrastate rules are the same.

 

8 days out of 30... next 30 you start fresh again

 

It's a rolling 30 days. Just like your 70 in 8.

 

If I worked 2 days per week OTR...then worked the rest of the week 100 mile radius( no log book needed) and amounted to 8 days needing to log per month..would that mean I wouldn't need ELog?

 

Correct, just watch how the calendar falls because it is a rotating 8 in any 30 day period. You could exceed that limit if you are not careful.
