DON'T try and cut into the bus lanes from June 2. You may be caught on camera - from a bus. Ninety buses on 12 services will have cameras fitted on the front to help the authorities catch errant driver violating the bus lane rule, which is to ensure buses get an uninteruppted run down their lanes.

The buses with cameras will ply both the city areas and the heartlands, on services which cover the new areas designated as full day bus lanes, said LTA on Thursday.

Some cameras have already been fitted on SBS buses on a trial basis last year. Previous cameras on buses, introduced in the 1990s, proved unreliable and traffic wardens were then needed to enforce the bus lane rule.

Eleven stretches of road in the city, which are already designated normal bus lanes - operating only in the morning and evening - will be converted to full day bus lanes.

Full day bus lanes are in operation from 7.30am to 8pm on weekdays and Saturdays, except on public holidays.

All the new full-day bus lanes are in the Central Business District and include stretches on Grange Road, Bencoolen Street, South Bridge Road, Victoria Street, New Bridge Road, Hill Street, Robinson Road, Shenton way, Fullerton Road and Collyer Quay.
