The roads tend to get a little bit more crowded around the holidays, and this July Fourth will be no different, even though it falls in the middle of the week. In fact, the Wednesday holiday is part of the reason AAA expects a higher volume of travelers to take to the roads from Tuesday, July 3 through to Sunday, July 8. The automotive organization predicts an estimated 1.3 million New Jersey residents will travel at least 50 miles during the Independence Day holiday period, which is 4.1 percent higher than last year. Those planning to drive account for 84 percent of New Jerseyans who will travel for the holiday.

"The extra time, coupled with falling gas prices have helped encourage travelers to hit to roadway in force," said Cathleen Lewis, director of public affairs for AAA New Jersey Automobile Club. "While travelers continue to seek ways to economize, the longer holiday period allows for longer trips."

This estimate does not account for out-of-state travelers who will surely be contributing to the congestion on the roadways. With so many cars on the roads this week, it is especially important for drivers to put safety first. Checking tire pressure before hitting the road can help make the journey safer and improve fuel efficiency, as having too little air in the tires makes the car work harder and use more gas.

It is also a good idea to check fluid levels, from the oil and coolant to the windshield washer fluid, prior to a long journey. Low levels can be topped off, but you might want to consider taking the car to the Total Car Care Center at NJ State Auto Auction in Jersey City if you suspect a leak. The experts at the shop can inspect your vehicle and make necessary repairs so you'll be safer en route to your vacation destination this week.
