We recently installed a driveway and they ran the concrete up to the cinder block foundation the entire length of the house. Should I run a bead of caulk where the driveway and foundation meet to prevent water penetration and possible freezing this winter? The drive way is about 5” thick.

I would suggest using (can't think of the name) It comes in gray, is available at Home Depot in the concrete section, comes in a caulk gun sized tube and is a self-levelling compound.
It is NOT a concrete patch. Just looked and couldn't find it on their website.

It remains flexible after curing and weathers very well. Apply it slowly as it will flow and overflow the joint. Try to not touch it after a couple of minutes as it gets tacky and will mar the otherwise smooth finish.

If HD doesn't have it, you may have to try a concrete supply company.

Mike's advice is good. Be aware that the chances of the caulk maintaining a seal between the foundation and the driveway isn't really very good for long periods of time. Plan to redo the work every couple of years. Even the best eurethane caulk won't be lifetime stuff.

This was bugging me so I called HD. They still carry it. It is made by Sika and is a self-levelling sealant. It forms a rubbery surface when it cures. Ours has been down almost 3 years and is still in perfect shape. It's not cheap; about 3 times the cost of caulk, but it's worth it.

Again, it will flow. I had expansion joint material underneath it so there was a bottom. I do recall in a couple of places it just disappeared into a small hole which I had to plug with slices of wood before proceeding.

Once again the world has moved on without me. I'll have to try this pourable sealant. I know that the DOT uses it in paving joints in highway.

If you have a ready mix supplier in your area, they often have and sell great products for this too. I have found their pro type, self leveling and thicker crack compound superior to any that I've purchased at home stores. They also sell all diameters of backing rod cheaply, by the foot (the flexible closed foam roping)that you can shove down into an open crack, so the caulk does not disappear on it's way to China.
