Answer: The correct sentence is;
'<em>'Before 8 a.m., traffic is light; however, at 5 p.m., Fred always wishes that he drove a bulldozer to push other cars out of his way.''</em>

There should be a semicolon after the word light because this joins the two contrasting clauses (one where traffic is light and the other inferring heavy traffic). 
The conjunctive adverb, <em>''however'' </em>is properly used in the sentence to link the two independent clauses.
