In furtherance of its clean air campaign, California passed a law that required all non-electric commercial vehicles driving on its roads to purchase and display an annual pass. The pass cost $200 and the proceeds from the sale of the passes went to a fund used to research and implement technology to reduce carbon emissions known to pollute the air. Toys R Us, a large commercial shipping company incorporated in Pennsylvania, whose trucks would sometimes drive through California and therefore be required to purchase a pass, filed a lawsuit challenging California's law as being unconstitutional in that it violated both the Due Process Clause and the Commerce Clause.

Does California's law satisfy the Due Process Clause? Why or why not?

Does California's law satisfy the Commerce Clause? Why or why not?
