spur of the moment
Tell the truth. Bring in pay stubs to show you actually have a job and maybe something from your boss. Apologize. Say you did something stupid on the spur of the moment and you regret deciding to drive rather than missing work or going in late if you were lucky enough to find someone to drive you there. Explain why you couldn't have called a cab, walked, or ridden a bike. Say you won't ever be that foolish again and you are willing to do whatever the judge wants you to do in order to prove it.
Then find out exactly what you have to do when the time for the restriction runs out. Surely there is something more than getting into your car and driving it.
It might also be smart to address why you had your license suspended and what you are doing to make sure those actions never happen again. Join AA for drinking, paying your parking tickets, whatever. Play that by ear.
