You didn't tell us which State you're talking about. It varies from State to State. In Illinois, the "Interstate" limit is 55mph. However, in inclement weather, one is expected to reduce speed to accommodate such.
In Illinois, for example, you would never get a ticket for reducing your speed, say, to 45mph to address severe weather.
Also, are we talking about "Interstates", "County roads", "City roads", etc ??
It varies. However, it is always safer to reduce speed if hazardous conditions call for it. You'll never be ticketed for it, if, in the opinion of any law enforcement agent, you are acting with due discretion. And they would always respect that.
Drive safely.

Slow down from your normal speed. Be prepared to stop safely in emergencies.
On a wet road with snow and slush, you should not be traveling more than 50 mph. It will work fine at that speed.
a wet road also see hydroplaning
Your vehicle will not grip the road as under normal conditions. You must reduce the speed, increase the safety distance from other vehicles and reduce the torque on your wheels by driving in the highest gear possible for your speed.
Quite a bit especially if your tires are worn down to or below the tread depth limit.
A wet road has less friction since the water acts as a lubricant.
Two reasons. The wet road has a lower coefficient of friction that the dry one. It is more slippery. The same goes for the brakes. If they are wet, they will be less effective because of the same reason. A higher amount of friction wastes more energy, in this case momentum, causing a loss of speed. http://en.wikipedia.org/wiki/Friction
When you slide on a wet road surface you are aquaplaning, also known as hydroplaning.
because the rough surface is wet and a road is not :)
Less traction on a wet road so the stopping distance increases.
Yes. There is less frictional force between the car tyres and a wet road surface than with a dry road surface.
