SEATTLE -- The only cure for Seattle traffic? Tacos, of course. A food truck reached hero status on Monday after opening for business in the middle of a major traffic jam.

Rachel McQuade and her husband were caught behind a tanker that overturned on I-5 Monday morning, blocking all southbound lanes. Then the couple noticed a bright green beacon of hope: the Tacos El Tajin food truck. The clever truck operators opened for business right there on I-5, even accepting debit cards for payment.

After more than three hours, southbound drivers were released will full tummies and a great story to share.
