21 car rental tips to know before you travel

1. Shop around

Shopping around online is the best way to find cheap deals and save money. Comparison sites like Booking.com and Rentalcars.com are a convenient way to explore the entire car rental market.

Remember to look beyond simple pricing. Choose a car rental company that's reliable, reputable and meets your needs.

2. Look for discounts

Any good online shopper knows to check for all available discounts before completing a purchase. Look for any discounts or promotional codes you can find.

You should also look for any discounts that apply to memberships you hold.

3. Choose the right vehicle

Choosing the right vehicle ensures you have a more affordable and safe trip. Here are some pointers to keep in mind:

  • Keep it simple: It might be tempting to hire a shiny new BMW or Mercedes convertible, but these cars can add headaches to your trip. You'll have higher costs to cover if things go wrong on your trip, and these cars can carry greater risks of theft. It's best to stick with a more sensible ride.
  • Choose the right size: If you're travelling with your whole family, you probably need a larger vehicle. However, smaller cars can be more suitable for areas with tight, narrow roads. They're also generally cheaper to rent.
  • Consider your engine: While a compact or economy car can present a better deal, smaller engines can struggle on sharp inclines. Keep this in mind if you're visiting steep or mountainous areas.

4. Book in advance

As soon as you’ve confirmed flights, it’s worth arranging a rental car. The earlier you book, the cheaper the deals. If there are plenty of rental cars available for a certain date, the price will be lower, in line with demand.

5. Choose the right location

Exactly where you pick your car up from can affect the price you pay. Airport pick-ups are typically more expensive, so it's worth considering a city depot instead.

However, you also need to factor in the costs of actually getting to the pick-up location. Look at public transportation options and calculate the best option for you.

6. Consider your rental car insurance options

When booking in your rental vehicle, you might choose a level of insurance cover from your rental company and never think twice about it. This approach won't help you get the best value.

Instead, look at external providers such as RentalCover. We offer protection that's more comprehensive than the rental companies while also being 50% cheaper.† Plus, there's nothing for you to pay in the event of a claim.

The most important thing is to do your research and find a provider that's right for you. Set some time aside for this well before you set off on your travels. You should also consider any cover your personal auto insurance may provide.

7. Avoid upsells at the rental desk

If you don't have your rental car insurance organised before you get to the rental desk, you may face significant pressure when picking up your vehicle. Rental companies may pressure you into buying insurance that offers poor value or that you simply don't need.

If you have a policy offering damage and theft protection from RentalCover, you can confidently decline any overlapping insurance offered to you at the rental desk. Make sure you have a digital copy of your RentalCover policy to demonstrate your cover to your rental company.

8. Watch out for the car insurance excess

You might think your car rental insurance has you covered for surprise costs when things go wrong on your holiday. However, you can still face a significant expense when you make a claim: Your excess.

This is the amount you must contribute when you make a claim, on top of the payment made by your car rental company or insurer. Insurance offered by car rental companies often has very significant excess you'll need to pay in the event of a claim.

If you have a policy with RentalCover, there's nothing for you to pay in the event of a claim. You can travel with true peace of mind, knowing you're protected against the unexpected.

9. Understand minimum age requirements

Your age can impact the car rental process in a number of ways. You might not be able to rent a vehicle in a certain jurisdiction due to your age.

If you're within a few years of the minimum rental age, you'll often face specific fees for renting a vehicle as a younger driver. Keep this in mind as you shop around for your vehicle.

10. Check the cancellation policy

Travel can be unpredictable, so make sure you understand how things will play out if you have to cancel your rental. Can you get a full refund? How much notice do you need to provide?

Make sure to read the fine print so you aren't caught unawares.

11. Mind the fuel policy

Refuelling policies are a common pitfall for many renters. Review your rental agreement and confirm the policy at the front desk if you're unsure.

Many rental companies have "full-to-full" policies. This means the car will have a full tank when you pick up, and you must also return it with a full tank.

You might also be able to pay a fee for pre-paid fuel, meaning you don't need to worry about refuelling before returning the vehicle. Consider your options and weigh up cost vs convenience to make your decision.

12. Avoid multiple drivers

Many hire companies charge you per day for additional drivers. Unless you’re planning on taking a long road trip where you’ll need to take turns, it’s best to stick to one driver.

13. Research the fees

Rental agreements are often packed with hidden fees. When added up, they can make a significant dent in your wallet. Here are some more common fees to look out for:

  • Additional mileage: Some rental car companies set a cap on how many kilometres you can travel per day, charging you more if you exceed it.
  • Credit card surcharges: Check your credit card statement a few days after you make the payment. Make sure no extra surcharges have come out and all excess charges, including fuel, have been returned to you.
  • Late pick-up: Always enter your flight details when you rent a car. This means staff know if your flight is delayed and shouldn’t rent your car to another customer. If you're not collecting from an airport, make sure you give yourself plenty of time to get to the depot and always inform them of any delays.
  • Late return: When returning the car, many companies give you a “grace period”. However, many companies start charging an hourly rate after 29 minutes. Figure out how your rental company operates and plan accordingly.
  • One-way/relocation fees: Some rental car companies waive these fees for certain one-way trips that align with fleet needs.

14. Prepare for international driving

 Driving in another country can be a stressful prospect. Here are some steps you can take to ensure you're fully prepared:

  • International Driving Permit (IDP): If your licence is in a language that is not a primary language in your destination, you'll generally need an IDP. Ask your rental company if you're not sure. Make sure that you secure an IDP with plenty of time to spare before your trip.
  • Road rules: Your destination may have very different road rules and customs to your home country. Do plenty of research to ensure you're prepared before you hit the road.
  • Rental insurance coverage: Rules around rental insurance are also very different around the globe. For example, outside the United States, there's typically much more cover built into the price of your vehicle. For more information, check out our complete guide to worldwide car rentals.

15. Consider paying upfront

Some car rental companies offer discounts if you pay for your entire rental upfront. Consider if this is an appropriate option for you.

16. Keep privacy in mind

Think twice before connecting your smartphone to your vehicle. While this can be a convenient way to navigate unfamiliar territory while listening to your favorite music, infotainment systems like Apple CarPlay can retain your information long after you return your vehicle.

If you do want to integrate your smartphone, speak with your rental company about the correct ways to disconnect it after you return your car.

17. Prepare your debit or credit card

When picking up your rental vehicle, you'll usually have to put down a security deposit. Make sure you have enough money accessible on your credit card or debit card to cover the cost.

Ensure that your bank will allow a large payment to go through without causing headaches. This could be particularly difficult to navigate when you're overseas.

18. Bring your own accessories

Accessories like GPS and child car seats can be surprisingly costly when hired from your rental company. If possible, consider supplying your own accessories. Just remember to ask your car rental company what their policies allow.

19. Record all damage

Before taking off in your rental vehicle, make sure you comprehensively record all of the damage that exists on the vehicle. Take photos and a full 360° video of the car so you're protected when it comes time to return it.

20. Ask about tolls

In many places around the world, toll roads are a necessity of convenient travel. Speak with your car rental company about how you can pay for tolls.

Many rental companies offer toll passes for a set fee at the beginning of your journey. Alternatively, you can offer to take care of toll payment yourself.

Consider how convenient a toll pass will be for you and what value you'll get out of pre-paying with your rental company. If you'll only take a toll road once or twice on your trip, it may not be worth it for you.

21. Return the car on time

Rental companies typically don't offer much leeway when it comes to returning your vehicle. Even returning your vehicle one or two hours late can mean facing expensive late return fees and/or being charged for a whole additional day of usage.

Plan carefully to ensure you can return your car on time. If you expect any delays, inform your rental company as soon as possible.

When is renting a car a good idea?

Renting a car can add a lot to your travels. Here are some situations where it's worth considering hiring a rental car:

  • You are travelling to a destination with limited or low-quality public transport.
  • You want to travel to specific attractions not accessible by public transport.
  • You want to enjoy a more spontaneous holiday, where you won't be locked into a public transport schedule.

What do I do if I get into an accident in a rental car?

Here's the process to follow when you get into an accident in a rental vehicle:

  1. Check for injuries among all affected parties. If anyone is hurt, contact emergency services immediately. Move to a safe location if possible.
  2. Report accidents involving death, injury or significant property damage to the police. For non-emergencies, contact a local police station rather than the emergency number.
  3. Take comprehensive photos and/or videos of all vehicles, damage, road conditions and the accident location. You should also collect the names and contact details of any witnesses.
  4. Exchange driver details, vehicle registration, insurance information and contact details with the other party. Make sure not to admit fault while doing this.
  5. Notify your rental company of the incident as soon as possible. They will guide you through their process and may arrange a replacement vehicle.
  6. Settle your charges with your rental company, making any appropriate payments. Once this is complete, you can submit a claim through your online account if you have a RentalCover policy. Typically, we process claims within 5-7 business days.

What are common car hire mistakes to avoid?

  • Failing to properly consider your options for insurance, and purchasing rental company cover that's less comprehensive and more expensive than alternatives.
  • Purchasing overlapping insurance at the rental desk that invalidates insurance from a third party provider like RentalCover.
  • Failing to properly record damage on your rental vehicle.
  • Picking up your vehicle from the airport when you could have more affordably picked up a vehicle from a city depot.
  • Returning your vehicle late, failing to understand the significant financial penalties this can expose you to.
