google sheets – Determining type of hours worked past certain time of day

Link to sheet:

Our business pays a different rate for drive time vs. site time. We also pay overtime (over 8 hours), and double overtime (over 12 hours). Sometimes we also have a crew going to several different job sites in a day (no more than 7). Therefore I can have several different pay categories:

  • Drive
  • Site
  • Drive (Overtime)
  • Site (Overtime)
  • Drive (Double Overtime)
  • Site (Double Overtime)

Using IF and AND in combination I can determine Site (DOT) and Drive (DOT). My issue is properly determining Drive (OT) and Site (OT). I have somewhat of a solution in mind using IFS and AND in combination but it seems cumbersome and clunky. Any advice is greatly appreciated.

I have formulas in cells on the sheet listing total hours, hours after break, total overtime, etc.

Here is what a selection of the times looks like
