I'm thinking of driving above the speed limit since my wife is at work.
You'll get a ticket and possible get into an accident.
I am also worried about that since my wife will get really mad
Stick to the speed limit. For the sake of your family that needs you there for them.
Yes, I'll keep that in mind.
Good. Driving the speed limit will ensure that you arrive at home each evening to your loved ones. Just remember to adhere to the speed limit signs.
