(Mexico City) -- Mexican cargo trucks are expected to roll across the international border between Mexico and the U.S. in about four months.
That word comes from officials in Mexico City, who say an agreement between the two nations could be signed in May or June.
However, the document is expected to be the target of congressional scrutiny.
Last week, President Obama said both nations are on their way toward resolving the issue.
The 1994 North American Free Trade Agreement called for trucks from Mexico, the U.S. and Canada to travel freely through the three nations, but the Mexican trucks have been stalled over safety concerns and other issues.
