Pack your bags and hit the road!
That's what more than an estimated 38 million Americans are doing this weekend, making it the busiest Memorial Day weekend since 2005 and one of the busiest on record. The AAA estimates that 700,000 more people will be traveling this weekend compared to last year—and almost 90 percent of them will be driving.
So what's motivating these road trips? Low gas prices. While prices at the pump are at their highest level for the year (the current national average is $2.32 a gallon) it's at the lowest Memorial Day price level since 2005.
"The ten year Memorial Day average is $3.15 so we're significantly below that," Senior GasBuddy.com Analyst Vera Gibbons told CNBC's "On the Money" in an interview. Meanwhile the money's adding up in ways most economists say works like a giant tax cut.
"Americans have saved $18 billion dollars on gasoline so far this year compared to last," said Robert Sinclair Jr, AAA's NY media relations manager.
Other factors persuading Americans to drive rather than fly include avoiding long waits at the airport's security checkpoints, heightened fears over terrorism and the Zika virus raging overseas, which experts say is likely to surface in the mainland U.S. sometime this summer.
"Europe travel is down by 13 percent [and] you've got the Zika virus that has a lot of families saying 'We don't want to take a beachy vacation to the Caribbean or Mexico, it's too risky," said Gibbons.
