The Worst Moment to Travel for Thanksgiving 2016 in Maryland

When are drivers most likely to fill Maryland highways and interstates as they travel for Thanksgiving 2016? The worst day of Thanksgiving travel in the region is fast approaching; it's the day before Thanksgiving. And if you want to hit the worst traffic imaginable, leave at 3 p.m. on Wednesday.

Google Trends released some holiday tips using historical Google Maps traffic data. The best time to leave has already passed: it was this Sunday at 6 a.m. The worst time to be on the roads is the day before Thanksgiving, Nov. 23, at 3 p.m.

When you're coming home, do it the day after Thanksgiving, Friday at 6 a.m. The worst time is Saturday at 4 p.m., according to Google.

Traffic app Waze tells ABC News the best and worst times to hit the road for the holiday weekend. The good news: If you're traveling on Thanksgiving, Black Friday or the next day, Saturday, Nov. 26, you should be in great shape.

But drivers who plan to leave on Wednesday and return home on Sunday should rethink their itinerary. Waze predicts that Wednesday morning will be OK, but the afternoon and evening will see a 20 percent increase in traffic jams.

That's not bad compared to Sunday, when traffic jams are expected to increase by 240 percent.

The five busiest airports for Thanksgiving travel will beDallas/Fort Worth International Airport, Los Angeles International Airport, Chicago O’Hare International Airport, John F. Kennedy International Airport in New York, and Hartsfield–Jackson Atlanta International Airport. So if you're waiting for a last-minute deal to open up, try to avoid those busy hubs if you can; they also have some of the highest cancelation rates for flights.
