Renting a car seems straightforward, but a few small oversights can lead to unexpected costs and complications. If you want your trip to go off without a hitch, it helps to be prepared. These are the common mistakes to avoid when booking a car rental. With this information, you’ll be set to rent a vehicle without any surprises.
Not Reading Reviews
Before you commit to a rental company, take a moment to see what other customers have to say. Reviews offer genuine insight into the company’s reliability, customer service, and vehicle quality. Look for patterns in feedback. Do multiple reviews mention hidden fees or poor vehicle conditions? Consistent comments can be a red flag.
Pay attention to reviews that detail the entire rental experience. This gives you a complete picture of what to expect.
Choosing the Wrong Vehicle Size

It can be tempting to choose the smallest, cheapest car available. Or maybe you think a larger vehicle will provide more comfort. Selecting the right size is about balance. Think about your actual needs for the trip.
Account for Usable Space
Consider your passenger count and the amount of luggage you’ll bring. While a smaller car might be budget-friendly, it’s no good if your bags don’t fit in the trunk. Always check the vehicle’s luggage space before making your reservation.
Think About Fuel Economy
A larger vehicle will likely use more fuel. If you have a lot of driving planned, the extra cost at the pump could add up. Find the right balance between space and fuel efficiency.
Overlooking Insurance Options
Rental car insurance can be confusing. You’re often presented with several options at the rental counter, and it’s easy to feel pressured into a decision. Understanding your coverage beforehand is a great way to avoid unnecessary expenses.
Check Your Personal Policy
Your personal auto insurance might already cover rental cars. Call your insurance agent to confirm the details of your policy. Ask specifically about liability, collision, and comprehensive coverage for rentals.
Review Your Credit Card Benefits
Many credit cards offer rental car insurance as a perk. This coverage is usually secondary, which means it kicks in after your primary insurance. Read your card’s benefits guide or call the customer service line to understand what’s included and any restrictions that apply.
Not Reading the Fine Print
The rental agreement is a legal document with all the terms and conditions of your rental. It might be long, but skipping it can lead to costly surprises. Pay close attention to sections on fuel policies, mileage limits, and additional driver fees.
For instance, some companies require you to return the car with a full tank of gas, while others offer a prepaid fuel option. Knowing these details will help you avoid extra charges. If you’re looking for a car and truck rental in Birmingham, Alabama, reviewing the agreement helps you understand the local rules and company policies specific to that area.
Forgetting To Inspect the Vehicle
Before you drive off the lot, do a thorough inspection of the car. Don’t rush this step. Any undocumented damage could be blamed on you when you return the vehicle.
Walk Around the Exterior
Look for scratches, dents, and any other cosmetic damage on the outside of the car. Check the tires for wear and proper inflation. Make sure all lights, including headlights, taillights, and turn signals, are working.
Check the Interior
Inside the car, look for tears in the upholstery, stains, or any broken components. Check the mileage and confirm it matches the number in your rental agreement. Photograph or record the entire vehicle as proof of its condition before you leave.
Disregarding Additional Driver Fees
If you plan to share the driving with someone else, you need to add them to the rental agreement. Most rental companies charge a daily fee for each driver. This fee can vary, so it’s a good idea to ask about it when you book.
If you don’t register everyone who’ll be driving, it can have serious consequences. Your rental insurance could be voided if an unauthorized driver leads to an accident. This would leave you financially responsible for any damage.
Underestimating Tolls and Fees

When you plan your travel budget, don’t forget to account for tolls. Many highways, bridges, and tunnels require payment. Rental companies often offer electronic toll devices for convenience, but they come with a daily service fee plus the cost of the tolls.
You can preview your route ahead of time to see if there’ll be tolls along the way. Apps like Google Maps can show you toll-free routes. If you can’t avoid them, consider paying with cash where possible to prevent the rental company’s service charges.
Missing Prepayment Deals
Many rental companies offer discounts if you pay in advance. This can be a great way to save money, especially if your travel plans are firm. Look for “pay now” options on the company’s website when you book.
Just be aware that these prepaid rates are often non-refundable. Weigh the potential savings against the flexibility you need.
Not Joining Loyalty Programs
If you rent cars often, joining a rental company’s loyalty program is a smart move. These programs are usually free to join and offer a range of benefits. Members can skip the rental counter, get free upgrades, and earn points toward free rental days.
Even if you don’t travel often, it’s worth signing up. There’s no cost, and you might get a better experience just for being a member.
Returning the Car Late
Rental agreements specify a return date and time. Returning the car late, even by an hour, can result in extra charges. Some companies will charge you for an additional day.
Plan your return carefully. Allow plenty of time for traffic and refueling. If you think you’ll be late, call the rental company as soon as possible. They might offer a grace period or work with you to avoid a hefty fee.
