Even the best-planned road trips could be riddled with problems the moment you leave the house. While one hopes for seamless travels and happy memories in the making, sometimes, unfortunate circumstances arise.

Some of the most common road trip mistakes can put a real damper on your vacation plans. However, there are ways you can avoid such troubles and enjoy the ride.

Here are eight typical road trip mishaps and ways to prevent them.

1. Forgoing an Auto Tune-Up

If it's been some time since you've had your car inspected, schedule an appointment for a tune-up one or two weeks before you embark on your road trip. The last thing you want to worry about is your car breaking down on the side of the road.

Some auto tune-up checklist items include:

• Exhaust system for fuel efficiency
• Tire pressure, wear and alignment
• Steering and suspension
• Braking system
• Fluid levels, such as coolant and oil
• Battery charge

Just in case, be sure you know who to contact for roadside assistance.

2. Driving Long Stretches Without Breaks

It's crucial to factor in breaks as you drive. Especially on longer road trips, stopping at rest areas to stretch your legs will help you beat fatigue during your long journey. If you’re driving with other adults, take turns driving different legs of the trip.

For road trips taking more than 10 hours, consider booking a hotel room or staying with a friend nearby to get some rest and break up the drive into two easier stints. Never continue driving if you’re tired, or you risk an accident.

3. Leaving Your Toll Transponder at Home

Do you anticipate tolls on your journey? Make sure your toll transponder is in your car and has enough funds to pay the fees.

In some cases, you may pass through toll-by-plate areas, but it can still be beneficial to make sure your toll transponder is loaded up and good to go — certain tolls offer a discounted price for drivers with the correct transponders.

To cover all your bases, keep some cash and change in your car’s center console, just in case you need to pay tolls that way instead.

4. Failing to Download Maps and Entertainment

Always download music and movies over Wi-Fi before leaving to avoid unwanted data charges on your mobile phone. Having a few films to watch will keep younger children occupied during lengthy travels. You'll also want to download trip maps in advance.

Some of the best travel apps to have on your phone include Roadtrippers, Google Maps, Waze and GasBuddy.

5. Being Unprepared for Weather

Each year, 116,800 people are injured in vehicle crashes on snowy, icy roads — 1,300 are killed. If you're planning a trip to a colder region, it's best to prepare with the proper tires and warm essentials. Swap out your all-weather tires for snow tires and pack blankets in case your car breaks down.

Keep an eye on the weather before traveling. Download a free weather app to stay on top of future forecasts. For example, the Weather Channel app will show you forecasts 15 days out so you can plan accordingly.

6. Traveling Without a Cooler and Snacks

If you're on a long road trip, fast food and gas station snacks and sweets will get old quickly. You also risk an uncomfortable drive with an upset stomach.

Always pack a cooler with healthier snacks, homemade sandwiches and fresh produce. Grapes, nuts, pre-cut carrots, celery, cucumbers and hummus make a great snack to munch on. It's also essential to pack plenty of water for your journey.

7. Forgetting Essential Paperwork at Home

Depending on where you get pulled over, driving without a license, registration and insurance could result in hefty fines and other legal repercussions. Make sure you have your driver’s license in your wallet and keep your registration and insurance in the glove box for easy access.

Other essential documents you shouldn't leave at home include health insurance cards, a list of medications, passports if crossing the border and travel itineraries for hotel stays.

8. Traveling Without an Emergency Kit

The last thing you want to worry about is getting hurt during a road trip. However, accidents happen. For unforeseen circumstances, remember to pack a first aid kit with bandages, gauze pads, tweezers, a thermometer, ointment, aspirin and antiseptic wipe packets.

Likewise, you should put together an auto emergency kit. Spark plugs, tire pressure gauges, bungee cords, air inflators, flashlights and pocket knives are just some items to bring. Safety flares are also a good idea if you're going on a camping trip or somewhere remote.

Don't Allow Common Mistakes to Derail Your Road Trip

Road trips are the best way to see parts of the country you never thought you would. You just need to plan carefully to ensure a mishap-free journey. Knowing the most common travel mistakes will ensure a smoother drive.
