The Washington, D.C. area's best—as in shortest time to get to work—weekday commute is on Friday mornings, according to data compiled by Inrix for Governing magazine.

But Friday is tricky—the Friday afternoon commute in the D.C. area is the worst of the week, according to the report.

The reasoning behind the best/worst commute day? Mornings are likely light due to federal employees taking advantage of telecommuting policies, the report said. And Friday afternoon is probably the worst due to people traveling for the weekend throughout the area and through the area on I-95 and the Beltway.

The report showed that D.C. ranked 9th in the country for Friday commutes and its traffic on Fridays is 25 percent longer than without any congestion. That adds nearly 8 minutes to a typical 30-minute drive, the report noted.
