Reduced daily rest, is this legal?

Gembo:
start drive at 0600,
total drive time, 10 hrs (4.5+4.5+1 hr) plus 2 hrs other work.
Finish shift at 1800 hrs.
Take Reduced rest of 3 hrs.
Drive again for 1 hr.
Take 12 hours rest.

Confused !!
Start at 0600
Finish at 1800
So that is a 12 hour shift
That shift according to you was 10 hours of driving + 2 hours of other work = 12 hours
WHERE ARE THE DRIVING TIME BREAKS of at least a total of 1.5 hours :question:
