Holiday travelers can expect to run into heavy traffic during the Thanksgiving holiday weekend.
Millions of people are expected to hit the roads Wednesday in advance of what's traditionally the busiest travel period of the year.

There may be one way to avoid the worst congestion, says AAA Mid-Atlantic spokeswoman Jenny Robinson.

"We're noticing the travel really happens kind of all day but if you can leave especially early or late, if you're willing to travel late in the day, the volume usually drops," she said.

Before heading out, drivers should do more extensive vehicle checks of tire pressure, window wiper blades, and car battery, Robinson suggests.

AAA also advises against driving for long stretches of time. Instead, Robinson suggests planning to take short breaks to stay more alert on the road.

She says drivers' best bet is to leave for their Thanksgiving destination really early on Wednesday or really late.

But, Robinson adds, don't expect to be consoled with a peaceful return trip.

Sunday is expected to bring the biggest traffic rush as people head back home, but it can't be avoided simply by waiting a day.

Routes also tend to be clogged on Monday, the first day of rifle deer season in Pennsylvania. AAA advises traveling on Saturday when traffic may be minimal.
