Alappuzha: The number of candidates passing the online learner’s test required to obtain a driving licence has dropped sharply, with applicants attributing the mass failures to recent changes introduced in the question paper.

Previously, the test comprised 20 questions, but it now includes 30. Candidates must answer at least 18 questions correctly to pass.

A major challenge for applicants is the introduction of CAPTCHA-based questions. After every three standard questions, candidates are required to answer one by typing a CAPTCHA, a mix of upper and lower-case English letters and numbers. This process repeats throughout the test.

The time limit for each normal question is 30 seconds, while CAPTCHA-based questions allow 45 seconds. Many candidates say the typing requirement slows them down, particularly those with limited computer skills. It is estimated that around 80 per cent of candidates are unable to complete the test within the allotted time. Those attempting all 30 questions must respond to nine CAPTCHA in total.

Candidates who fail must reapply, often facing long waits to secure a new test date. Since passing the learner’s test is a prerequisite for taking the driving test, delays have caused difficulties for students and working professionals, who are forced to take multiple days off.

Officials said the National Informatics Centre (NIC) introduced the intermittent CAPTCHA system nationwide after fake learner’s certificates were found being issued by agents in North India.
