Barbados' infrastructure is well developed and the entire island is covered by a good network of roads, although many of which are unpaved and covered in potholes. Traffic drives on the left.
Buses and taxes can get you anywhere in the island for a flat rate charge for all journeys. Buses are relatively a cheap mean of transportation for getting around, which is usually crowded during rush hours, though ease to catch by just hailing one down. Yet taxis are unmetered and charge fares regulated by government, and offer special deals for a full-day hire.
Still, if you decide to hire a car and get around Barbados independently, you will need a Barbados driving permit, which can be easily obtained from any car hire company, the Ministry of Transportation, the airport or some police stations. All you will need is a valid national license or International Driving Permit and a small registration fee.
There are numerous car hire companies around Barbados offering a huge range of cars, anything from a most popular Mini Moke to a limousine. Scooters can also be hired, and all you will need is a small deposit to be paid, and a helmet which is required by the law.
Cars hire prices range anywhere from around 30 USD per day and up. Some agencies offer a service of finding a best priced car hire meeting your needs. They claim that you can save up to 50% of the price.
