Karnataka’s steepest-ever bus fare hike. The hike applies to KSRTC, BMTC, NWKRTC and KKRTC services, with fares rising by up to Rs 9 on KSRTC and Rs 10 on BMTC buses. Karnataka has revised fares across its four state-run transport corporations from midnight on November 4. The government says higher diesel costs and financial strain prompted the increase.
