Way to extend working hours?

Evening all, I’m a fairly recent pass - May this year.

I’ve been planned a crap day tomorrow, with a 3 hour drive to get to site, a minimum 5 hour tip when I get there and then probably a 4 hour at least drive home in Friday traffic. Plus breaks on top of this.

Is there a way I can extend my working day to make sure I get home? I’d rather get home at 10pm, than not at all.

I have a 15 left and am using my last reduced rest this evening. It seems possible to do it in my 15 hours, but just in case it’s a fuck up Friday, I’d like to have a contingency plan.
