Among the 50 regional transport offices (RTOs) in Maharashtra, 14 had a failure rate of less than 1 per cent among driving test applicants, while only six had a failure rate of more than 5 per cent, the data said. What is more serious is that in some RTO offices, the failure rate was below 0.50 per cent and a few had it more than 7-8 per cent. Experts say it is difficult to understand how so many drivers were passing driving tests, considering the alarming number of accidents on state roads.
