The traffic wing of East Singhbhum police launched a surprise checking drive in various parts of the steel city and collected around Rs 30,000 as fines on Wednesday.

The drive was launched simultaneously across four traffic police stations — Sakchi, Bistupur, Jugsalai and Mango.

During the crackdown, which started at 11 in the morning and continued for two hours, around 100 bikers and 40 motorists were caught flouting rules like riding without helmets or valid documents.

Helmet-less bikers had to pay Rs 270 as penalty. Driving without a licence invited a penalty of Rs 500 and missing insurance papers cost a biker or motorist Rs 1,000.

Bikers caught with number plates on the front had to shell out Rs 300.

DSP (traffic) Shivendra Kumar said such a drive would continue.

“It was conducted to make people as well as picnickers aware of the importance of traffic rules. Apart from generating revenue for the department, such drives also help instil discipline among people, especially youngsters,” he said.

Incidentally, rash and helmet-less driving witness a rise during the picnic season. Sources said special instructions had been given to all traffic police posts across the city to carry out surprise checking drives.
