Seventy per cent of road signs had design flaws and were installed at wrong places, the study said. It said of the 1,514 regulatory, warning and information signs on the surveyed roads, at least 1,098 or 75 per cent did not meet legal standards. Regulatory signs such as "stop" warnings have to be followed, while warnings signs are used to alert drivers of potential dangers ahead. Information signs provide details about distance and landmarks.
Depending on the category, these signs differ in shape, size and colour. But in Delhi, they have been interchangeably used, which often misled motorists, the study said. The study said most primary and secondary traffic signals at intersections were found to have malfunctioned or wrongly installed.
"One of the major deficiencies was short blinking green signals used instead of an amber signal. The duration of amber clearance before the red light appears is so short that in present conditions a large percentage of drivers are being caught without any fault," IRTE chief Rohit Baluja said.
The IRTE said the proposed Motor Vehicles Amendment Bill, 2016, which has been passed by the Lok Sabha, seeks penalties such as imprisonment of up to a year and fine extending up to Rs 5,000 for not following traffic signs.
The IRTE's study said the faulty signs did not meet requirements of the Indian Road Congress codes and the United Nations Convention of Road Signs and Signals, 1968, of which India is a contracting party.
Out of the 1,514 signs, 801 or 54 per cent, were inserted within either blue or yellow rectangular boards. "Blue is only permitted for compulsory regulatory signs as well as facility information signs. Yellow is not prescribed by the IRC except in construction zones," the study said.
It said the Public Works Department used blue outer boards while the New Delhi Municipal Council has taken the liberty of using yellow as insertion boards, making the signage "more of fashion and show rather than for regulation and warning".
