Slow Turn Puzzles

Find a loop that moves, horizontally, vertically, and diagonally that passes through all of the green squares, none of the red squares, and some of the white squares. Only shallow 135o turns are allowed. No square is visited twice, though the loop can cross itself. A sample puzzle is shown below. Each puzzle below has a unique solution.
