Four other taxi operators have notified the Public Transport Council of their decision to raise fares, following the lead of ComfortDelGro and SMRT. They are Trans-Cab, Premier, Smart Automobile and Yellow Top, whose cabs are owned by individuals with taxi licences.
Trans-Cab said basic flagdown fares will go up by 20 cents for most taxis, similar to changes by ComfortDelGro and SMRT.
Peak periods for which surcharges apply will also be extended.
Prime Taxis is now the only operator which has not yet decided if it will raise fares. Taxi firms must give commuters at least a week's notice before making changes.
SMRT's new fares started on Tuesday, while ComfortDelGro's began last Monday. ComforDelgro is the taxi industry's market leader, with more than 15,000 of the 26,000 cabs here. Trans-Cab is the second largest operator, with 4,300 cabs, followed by SMRT, with more than 3,000.
