The Barbados Road Traffic Act of 1941 Governs the Road traffic laws which specifically states how good your eyesight needs to be. You must be able to:
• Read in good daylight the (with the aid of glasses if worn) the registration number affixed to a motor vehicle at a distance of twenty-five metres in the case of a registration mark containing letters and figures ten centimeters high and at a distance of twenty metres in the case of a registration mark containing letters and figures seven centimeters high.
Visitors driving permit
All visitors that intend to drive in Barbados have to purchase a visitors permit. If you're renting a car it will probably be provided by the rental company. If you're borrowing a local car you will have to visit the local police station to buy your permit. The cost is low for short stays.
Visitors permit – $10.00 for less than two months
Visitors Permit – $100.00 for two months and over and up to a maximum of one year.
Age for driving
If you’re a citizen or resident of Barbados you can apply for a driving permit at the age of 16; you have to have successfully completed a theory test before you can apply for a permit. Your driving test will usually be taken within three months and on successfully passing a driving test you gain a license, provided you've completed the correct form and paid the exact fee.
If you see a stop sign you must come to a complete halt, before moving onto the next road safely. The police are extra vigilant with drivers at these signs, as many roads in Barbados have quite difficult line of sight locations. Quite often you simply can't see what traffic is coming along a road until you come to a complete stop. Some roads have large mirrors posted opposite difficult junctions so you can see if cars are coming down the road and are about to enter your junction or drive straight past you.
Don't even take a chance and think you can crawl around the corner at 3 miles an hour without stopping. The traffic police appear to spend the majority of their time placing their cars just around the corners of roads they know people quite often don't stop at. It'll cost you a substantial fine for driving at 3 miles an hour when you shouldn't.
