Americans hitting the road this weekend stand to see the cheapest Labor Day prices at the pump in over a decade, leading to huge savings- $1.4 billion- over the four day weekend.

“August gasoline prices plummeted by 18 cents per gallon, the greatest decrease since 2008, and as a result we have a national average that’s 99 cents lower than a year ago ($2.44 versus $3.43). I’m sure motorists will have plenty of company on the nation’s thoroughfares this weekend,” said Patrick DeHaan, senior petroleum analyst for

While motorists enjoy the cheapest Labor Day prices in over a decade, GasBuddy currently identifies as many as 19 states where at least one retail outlet is already selling gas below $2, while South Carolina is the lone state to see an average under that level: $1.995/gal. Nationally, gas prices stand some 21 cents below where they were just a month ago.

This weekend, GasBuddy analysts predict nearly 70% of the nation’s gas stations to be priced at under $2.50/gallon compared to 0% last year (currently 65.9%). A fact that may shock motorists: over the last 14 Labor Day weekends, the holiday itself had the lowest average: $2.744/gallon, while it was $2.75 for Sunday and $2.751 for Saturday and Friday.

Motorists in the south will spend the least, with 68.4% of stations in South Carolina at $1.99 or less. Other states that saw plenty of sub $2/gal gasoline: Alabama: 44.4%, Mississippi: 40.1%, Tennessee: 21.4%, Louisiana: 19.5%, Virginia: 17.8%, Arkansas: 10.4%. Nationally, some 8,060 stations are currently offering gas at $1.99/gal or lower.
