DUBLIN BUS has rowed back on its zero-tolerance policy that would have prevented drivers from using transistor radios. Dublin Bus confirmed that it had met with unions and confirmed that while the zero-tolerance policy against electronic devices would remain in place, it would not apply to transistor radios. In a notice to its members, the NBRU stated that during its discussion with the company it had also been concluded that there was no issue with drivers using electronic devices at bus terminuses and that emergency calls can be taken after a driver pulls over and turns the bus’s engine off.
