FAIRFAX, Va. (WUSA) -- AAA emergency road side assistance call volume is up 21% Wednesday over its normal volume.

It attributes the rise in calls because of the cold snap this week.

Meteorologist Howard Bernstein's says Monday we reached a high of 49 degrees in the Metro and by Wednesday we were in the teens and in some parts, the single digits.

The cold snap can really wreak havoc on our transit system and our cars.

Your car may have run perfectly the night before. Your battery may be fine. Your tire pressure is right. But overnight, and in the morning, it could be a whole different situation.

Aaron Dennis is a AAA mechanic and ironically both of his batteries in his diesel truck died.

"I had to start my own car. Both batteries were dead and they're only two years old. I've been working on everyone else's cars, that's my excuse, that's all I've got."
