Colour Blind Test for Drivers
Colour Blindness (Buta Warna)
People with colour blindness are unable to see certain or all colours. This abnormality can be dangerous and cause serious accidents on road. Because traffic signs and indicators follow colouring scheme internationally, people with colour blindness are not eligible to get a driving licence. Once colour blindness is realized, please contact your optometric physician immediately.
Following are the 3 types of colour blindness:
Red-Green Colour Blindness (Buta Warna Merah-Hijau)
This is the most commonly found type of colour blindness in which people cannot differentiate between red and green colour. There are four 4 types of red-green colour blindness:
People suffering from Deuteranomaly see green colour as more red. This is most common and mild type of colour blindness. Deuteranomaly is considered as mild colour blindness because it doesn’t affect normal routine activities.
People having Protanomaly see red colour as more green with less brightness. This type is also considered as mild and usually doesn’t signicantly disturbe normal activities.
Protanopia and deuteranopia affect people in the way that they are totally unable to differentiate between red and green colour.
Blue-Yellow Colour Blindness (Buta Warna Biru-Kuning)
Blue-yellow colour blindness makes it harder to identify difference between blue and yellow, and yellow and red colour. This type of colour blindness is less-common among people. Following are the 2 types of blue-yellow colour blindness:
Tritanomaly makes it difficult to make the difference between blue and green, and between yellow and red colour.
Tritanopia makes the people unable to tell the difference between blue and green colour, purple and red colour, and yellow and pink colour. It also makes colours look less bright as compared to their original brightness.
Complete Colour Blindness (Buta Warna Lengkap)
People with complete colour blindness issue can’t see colours at all. This medical condition is called monochromacy and is quite uncommon. People suffering from monochromacy not only face problem in seeing clearly but also are more sensitive to light.
To get Malaysian driving licence, candidates are tested for any possible colour blindness and vision deficiency problems. Passing colour blindness test is prerequisite to attempt the computer based traffic signs and rules test, and practical driving test. To test Deuteranomaly, Protanomaly, Protanopia, and Deuteranopia (Red-Green colour blindness types), you will be asked to indicate correct numbers, letters, and/or shapes, surrounded by coloured dot pattern, on a multiple choice response format. In addition to Red-Green test, candidates will also be asked to answer correct sample car registration numbers and basic colours in order to test their reading and colour detection ability. The duration of this test is 15 minutes only. Total 8 questions will be asked. To pass the test, candidate needs to achieve 100% marks. A distance of 75cm is recommended between computer screen and candidate to achieve good results. If a candidate fails in colour blindness test, JPJ will direct him to seek a medical advice and eye examination. Anyhow, JPJ will decline the application of all such candidates failed to qualify colour blindness test and vision deficiency test.
