If youre renting a car on your next vacation, you might want to spend a little extra time before you take off to avoid facing unwanted charges later on down the line. Many renters have overpaid for unnecessary insurance or received hefty bills for damages they did not cause. To save money next time you rent a car, Auto Travel World has revealed these rental car hacks you should follow.

　　Take pics and video of your car Before you even think about driving off, whip out your phone and start recording. Take a full walk-around video of the car's exterior and interior, making sure to capture the license plate, odometer and fuel level. This is your best defense against getting blamed for pre-existing scratches, dents or stains. Snap some photos of any damage and email them to yourself or the rental company. When you return the car, repeat the process and compare videos. Spot any new damage? Report it immediately and show them your video evidence. Simple and effective.

　　Only buy insurance if you really need it Dont let rental car companies upsell you on insurance you dont need. Chances are, youre already covered by your own auto insurance or your credit card. Before you rent, check with your insurance provider and credit card company to see what coverage you have for rental cars. You might already be protected against collision damage, theft, liability and personal injury. If so, confidently decline the rental companys insurance and save yourself some cash. Just be mindful of specific country requirements and any exclusions from your credit card, i.e. always read the fine print.

　　Avoid unnecessary fees Rental car companies love to tack on extra fees for things like fuel, tolls, GPS, child seats or additional drivers. Heres how to avoid them:

　　Fill up the tank: dont get hit with a premium refueling charge. Find a nearby gas station and top off the tank before returning the car. Keep the receipt as proof.

　　Understand the toll situation: avoid daily fees for rental toll transponders by using your own or paying cash. If you do use their transponder, check your bill for accuracy and dispute any excessive charges.

　　Bring your own gear: Save on GPS and child seat fees by bringing your own equipment. Use your smartphones navigation and rent a child seat from a third-party provider. You can also save by limiting any extra drivers. If you must add a driver, ensure they meet all requirements and are covered by your insurance or credit card.

　　By following these tips, you can dodge rental car scams and save money. Always read the rental agreement carefully, inspect and document the cars condition, and keep receipts for everything. If you do that, youve got smooth sailing ahead.
