Vision standards for driving in Trinidad and Tobago

ABSTRACT

Objective: To research the licensing system with respect to vision standards, and the process of assessing vision at licensing offices. We identified areas where there may be problems, which can hinder the safety of drivers and other citizens and proposed solutions for these issues. Design and Methodology: Methods of information gathering includedconducting interviews with the head licensing officer at each licensing office branch. Data such as the types of chart, distance from the chart and room lighting were also measured and recorded at each office. Information about the vision screening process was gathered through the interviews. Results: It was found that there were no set standards in Trinidad and Tobago for assessing the vision of individuals wanting to obtain a driver's license. Individuals performing the vision assessment at the offices were not trained to do so and did not perform it on everyone. There were variations in the types of chart used, the chart distance used for testing, and room lighting, which can significantly affect the results. Conclusions: There is room for improvement in the system and methods of vision screening in Trinidad and Tobago. Other features of vision testing including peripheral vision and contrast sensitivity should be taken into consideration for a proper assessment of vision to be done. There is also a need for more extensive research to be done to aid policymakers in making sound decisions.
