While allowing more traveling time is definitely important, there are a few other things that you will want to keep in mind whenever you are traveling in the rain.  One of them is the cruise control.  I know that I use the cruise control a heck of a lot and you want to make sure that you do not use it.  The reason for this is because you can lose control.

You can actually hydroplane on the road and that in turn, can cause a lot of accidents, as you could actually hydroplane right into another car, which is not a good thing.

You also want to make sure that you are braking really early as well, as your brakes are going to be slippery.
