Are the cracks that you see in the roads cause by a lower release of energy like what causes earthquakes?

No, the cracks in the roads are caused by physical weathering. When it rains or snows the water seeps into the road and when it freezes the water expands and the pressure the water exerts from freezing causes the road to crack and split apart.

The cracks are called frost heaves you often see warning signs on the highways.

I think that the cracks in the road acure because the roads have alot of tar in them and in the winter the road freezes which makes it more brittle and then 10,000 pound snowplows run over them.
