1099 worker mileage

I am a 1099 painting contractor for two painting companies. I do not have a registered LLC, corporation, etc. but I know as self-employed, the IRS technically considers me a "business" even though I don't have a business EIN. 

 

I do not go to an office for my employer or  principal business location (they run their businesses out of their home), just take my personal vehicle from my home to the site where we are working for the day. I am confused as to if I can claim mileage when i drive to and from our job sites or not on my tax return as I am seeing different responses with different answers and exceptions. any help would be much appreciated!
