Millions of Southern Californians will be taking to the roads on Friday as the Memorial Day travel crunch gets into high gear, and the heavy traffic will likely test the patience of motorists.

The Automobile Club of Southern California estimates that the worst time to travel will be between 3:30 p.m. and 5:30 p.m. on Friday as a record 3.21 million people head out by road, rail and air,

Among Southern California residents, 2.68 million are expected to travel by car to their destination, while 326,000 people will be traveling by plane. Another 202,000 people will be traveling by recreational vehicle, cruise ship, bus, train or other means of transit.

According to the auto club, the most popular destinations for Southern California residents will be Las Vegas, San Diego, the Central Coast, San Francisco and Yosemite National Park.

Before you leave, check traffic conditions on the Caltrans website and flight status at the San Diego International Airport.
