The ubiquity of the internet today means that you can do most things without leaving your desk - it also means that when making a trip, you can organise your car rental in advance in almost any location in the world, so that when you arrive, you can simply pick up your pre-booked car and go. To ensure that you car rental experience goes completely smoothly, there are a few things you should bear in mind before you even log on to that car rental website.

Decide before you book a car who exactly will be driving during your trip - a car rental does not usually allow you switch drivers without a previous arrangement, so decide in advance whether one person will do all the driving or if you and a partner might take turns at the wheel. Having the wrong person in the driving seat might have implications on your insurance. And always make sure that you have insurance. This can be arranged through your existing insurance company - ask whether your existing insurance will cover your rental car. Regardless of the type of car you decide to hire, don't skimp on insurance - it simply isn't worth the risk.

Depending on the nature of your trip, you will probably have particular requirements in your car rental - so decide before booking what features you will need in a car. How many passengers will there be, will you be carrying a lot of luggage? While a fast and exotic car might be great for impressing clients on a one man or woman business trip, it isn't quite so appropriate for long haul driving with the kids! Ensure that you car you select has plenty of room for both passengers and luggage, and meets any other special requirements you might have.

Don't forget when hiring a rental car to bring all the appropriate documentation with you - this is not the time to forget your driver's licence! It is also a good idea to bring a copy of the rental agreement in the car with you, just in case the police at any point stop you. And perhaps most importantly when renting a car in an unfamiliar location - don't forget the map!
