Four Things to Know for a Safer Fourth

Just because the country's another year older doesn't mean you have to be. Wearing your seat belt on any day makes you nearly a year younger. But that's especially true during the Fourth of July holiday weekend, one of the most dangerous driving times to be in a car. While you can't control others (we know you're not drinking and driving), here are four simple ways to help you, your passengers, and everyone else on the road get there and back safe and sound, so the only flashing lights will be in the sky:

1. Don't skimp on sleep. Some research suggests that driving while drowsy is like having two drinks and then getting behind the wheel. Coffee helps wake up your road skills briefly, but sleep is really what you need. Long weekends (the YOU Docs' favorite weekends are long ones) are great for snoozing.

2. Don't obsess about when you'll get there. Constantly refiguring how much longer the trip will take can backfire: In one study, mental calculations slowed the reaction times of all drivers -- especially older ones. Enjoy the journey.

3. Don't grab for something you've dropped. A roll of mints, toll money, a coffee cup -- forget it until you can stop. The chance of a crash or near crash goes up nine times while reaching for a moving object. Also, there's a reason Indy drivers don't eat and drink in the car. Sure, you're not traveling at 223 miles per hour, but it's still smart not to dilute your focus with food.

4. Don't primp until you pull in. Touching up your face on the road increases your risk of a crash or close call by three times. And you look fine! Honest.
