While this might be frowned upon in Austin, a Seattle 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 Interstate 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.

Rachel's husband got four tacos and a drink on the freeway - with a great story to share. After being stuck on I-5 more than three hours, southbound traffic was released in the northbound lanes to the West Seattle Bridge exit.

I-5 reopened to motorists after being closed for nearly eight hours Monday.
