1. Before beginning a long drive, always get enough sleep and eat a snack or meal. Highly caffeinated beverages are not necessarily the best way to stay awake while driving. While initially you will feel more alert, the effects can recede with time, and your attention may wander although you remain awake.
2. Pull over and take breaks every couple of hours, even if you don’t feel sleepy. Grab a snack, get some fresh air and stretch your legs by walking around. If you need to, take a quick nap.
3. If you can, share the driving responsibilities with someone else. This will allow you to keep an eye on each other while driving and also enable you to nap without losing time. If you’re driving alone, turn on the radio or put on some music, and keep your window cracked open. You may want to refrain from using your cruise control if you’re driving alone at night — having to concentrate on maintaining your speed can help you stay awake.
4. If you do have to pull over, move your vehicle off the road. Never park on the shoulder or in the breakdown lane for any reason except an emergency.
5. Know the laws along your route concerning cell phone use while driving. While it may be legal in one place, it may be illegal in another, and ignorance is not typically an acceptable excuse for a violation. Here’s a handy chart of cell phone laws by country and U.S. state (keep in mind that this information can change at any time). However, even if it’s legal to talk on a cell phone where you’re going, it’s usually safest to use a hands-free device.
6. If you don’t know this one, shame on you. Never drink any alcohol before your trip. While you may not become intoxicated from one beer, you will become sleepy.
7. Keep an eye on the skies, and if you can, plan a route around inclement weather. A minor detour could actually wind up saving you major time.
8. Use a smartphone app such as Waze or Google Maps to guide you around traffic jams.
9. Not even a GPS app is infallible, especially in remote areas, so we recommend bringing a detailed map or road atlas as a backup just in case.
10. If you are driving a rental vehicle, familiarize yourself with the car and all of its equipment (horn, brakes, hazard lights). For an amusing but true look at this issue, see The First 10 Minutes of Your Car Rental.
11. Lock all of your valuables (especially items that are clearly gifts) in the trunk or glove compartment and stow all luggage in the trunk. For more ideas, see Nine Ways to Keep Your Car Safe on the Road.
12. Familiarize yourself with local traffic laws, which vary from state to state and especially overseas. Is it legal to make a right turn at a red light? What are the rules on yielding to pedestrians? For more on driving abroad, see International Car Rental Tips.
13. Before setting off on a long car trip, be sure your vehicle is in prime condition — that tires are properly inflated, all fluids are at their proper levels and you have a full tank of gas. (For particularly long road trips, you may want to have your mechanic do a more thorough check.)
14. Consider becoming a member of AAA or CAA, or signing up for your car insurer’s roadside assistance program. You won’t regret it when your car breaks down on a lonely back road.
15. Keep costs down by conserving gas as you drive. Minimize sudden starts and stops, empty your car of all unnecessary weight, and slow down — in most cars it takes much less fuel to drive 55 miles an hour than it does to drive 70. For more ideas, see Save Gas and Money.
16. Don’t wait until your gas gauge is sitting on E to refuel. On an unfamiliar road, you never know when the next gas station will appear. As soon as you hit a quarter of a tank, start looking for a place to fill up. (Smartphone apps such as GasBuddy and Gas Guru can help.)
17. When traveling with kids, be sure to stop often — not just for snacks and potty breaks, but also for fun. See a cool playground along the way? Pull over and throw a Frisbee around. You’ll also want to pack toys, books and music for the car — not to mention your motion sickness remedy of choice. For more ideas, see the car travel section of our sister site, Family Vacation Critic.
18. Feeling munchy? Stock up on snacks and drinks at grocery stores rather than gas stations or convenience stores — you’ll get a wider and healthier selection, as well as better prices. For more advice, see Eating Well and Staying Active While Traveling.
19. On longer trips, keep napkins, plasticware and a small cooler handy for meals on the go. You’ll also want some spare change for tolls, as well as a first-aid kit, flashlight, pillow and blanket. Keep a set of jumper cables, a spare tireor donut, and extra fluids for the car (such as windshield wiper fluid) in your trunk.
20. This last tip should go without saying, but it’s important enough that we’ll say it anyway: Make sure everyone in the car buckles his or her seatbelt. Not only will it keep you safe, but in most places it’s also the law.
