The holiday season inevitably means congested roads and back-to-back traffic as Americans go about their holiday shopping, party hopping and trips home to family. But with the rising cost of gasoline, this hustle-and-bustle can come at a significant cost.

Why not try carpooling? According to this infographic from Carinsurance.org, just one day of carpooling can have an impact not just on your wallet, but also on the environment. Here are some highlights:

• There are more than 250 million cars on the road in the United States, which is more than one per American adult.
• The United States uses one-fifth of the world's oil to fuel those cars.
• Just 10 percent of Americans choose to carpool, saving a collected 85 million gallons of gasoline, avoiding 56,000 miles of traffic and saving $1.1 billion on gas and car costs per year.
