Renting a car for the first time? It can feel like a big step, but it’s actually pretty straightforward when you know what to expect. A rental car gives you the freedom to explore on your own terms. You’re not tied to public transport or dependent on rideshares. You can take the scenic route, make spontaneous stops, and travel at your own pace.
To help you get started, here’s what matters most when renting a car for the first time.

Get Clear on What You Need
Not all rental cars are created equal. Before you even start comparing prices at Mercury Rent-A-Car, think about what kind of vehicle will actually suit your plans. If you’re heading into the city, a smaller car can make parking easier and save on fuel. For longer road trips or if you’re travelling with family or friends, comfort and space matter more.
Also consider how much boot space you’ll need, whether you want automatic or manual, and any extra features that would make driving easier for you, like reversing cameras or built-in navigation.
Understand Licence and Age Requirements
You’ll need a valid driver’s licence, and in most places, you need to be at least 21 years old to rent a car. Some companies set a higher minimum age, especially for premium models. If you’re under 25, expect a surcharge, which is a common industry standard.
If your licence isn’t printed in English, you’ll probably need an International Driving Permit as well. This varies by country, so it’s best to check the local rules where you’ll be renting.
Don’t Leave Booking to the Last Minute
The earlier you book, the better your chances of getting the right car at a good price. During peak seasons, options can sell out quickly or get more expensive closer to the date. Booking ahead also gives you time to compare vehicle sizes, inclusions, and pickup locations without pressure.
Being flexible can help too. Shifting your pickup or return time by a few hours can sometimes lower the daily rate. Returning at the same time you picked up the car also helps avoid being charged for an extra day.
Know What’s Included in the Price
Not every rental quote includes the same things, so it’s worth double-checking the fine print. Some rentals come with unlimited kilometres, while others have a daily cap and charge extra if you go over. You’ll often see a “full to full” fuel policy, which means you’ll need to return the car with a full tank. Others might charge for fuel afterwards, usually at a higher price than local service stations.
Insurance is usually included, but this typically comes with an excess. You can choose to reduce the excess with optional cover, but it’s not required.
Before You Drive Off
When you arrive to pick up the car, you’ll need your driver’s licence, a credit card in your name, and your booking confirmation. Once the keys are handed over, don’t rush straight onto the road. Take a few minutes to check the vehicle.
Here’s what to look for before you leave the lot:
- Existing damage – Walk around the car and inspect it for dents, scratches, or chips in the windscreen. Make sure everything is noted in the paperwork.
- Fuel level – Confirm it matches what’s listed in the contract. Take a photo of the gauge if needed.
- Interior condition – Look for any stains, tears, or marks on the seats and dashboard.
- Tyre condition – Check they’re fully inflated and not worn down.
- Controls and setup – Adjust your seat and mirrors, and familiarise yourself with the lights, wipers, and other basics.
Doing this gives you peace of mind and helps avoid being blamed for pre-existing damage later.
While You’re Driving
Take it easy for the first few kilometres until you’re familiar with the feel of the car. If you’re in a new country, brush up on the local road rules beforehand. Some places have unique signs or laws that are worth knowing in advance.
Driving a rental shouldn’t feel any different from driving your own car. If anything, it’s a chance to experience something new. Most modern rentals are easy to handle and built with comfort in mind.
Navigation is worth thinking about too. If you don’t have built-in GPS, your phone will do the job just fine. Just make sure it’s mounted safely and not used in your hand while driving.
Returning the Car
Returning the vehicle is usually quick and easy, but it’s worth doing it properly to avoid fees later. Don’t just toss the keys in the box and walk away.
Before you return the rental:
- Fill up the tank – If your rental agreement says “full to full,” stop at a petrol station close to the drop-off point.
- Arrive on time – Late returns can lead to another full day charge, even if you’re just 45 minutes behind.
- Tidy up the interior – Clear out rubbish, return any accessories like phone holders or cables, and check for personal items.
- Final inspection – Ask a staff member to check over the car in person while you’re there. If that’s not possible, take photos from multiple angles.
- Request a receipt – Some places email this automatically, but asking for one on the spot confirms everything is closed out properly.
It takes just a few extra minutes and can save you hassle down the line.
Optional Extras to Think About
While they’re not essential, there are a few extras that can make your experience more convenient. If more than one person will be driving, adding a second driver is usually easy to organise. If you’re travelling with children, child seats are often available for hire, and some companies include toll passes to make driving smoother on toll roads.
You don’t need every add-on, so only choose what actually adds value to your trip. If you’re unsure about something, it’s worth asking when booking rather than waiting until pickup day.
Confidence from the First Turn of the Key
Renting a car for the first time is one of those things that sounds more complicated than it actually is. Once you’ve done it, it becomes second nature. The flexibility and independence it offers make it well worth it, especially for travel plans that don’t fit neatly into public transport routes or strict schedules.
Take your time, read the fine print, and make sure you’re comfortable before hitting the road. With the right mindset and a little preparation, you’ll not only get from A to B, but enjoy the journey in between.
