PROVIDENCE -- Rhode Islanders can expect more free bus rides this year because the state anticipates increases in the number of air quality alert days.

All regular state bus and trolley routes offer free transportation on air quality alert days, which state officials say will increase under stringent new federal ozone standards.

Air quality alerts are issued on days when high levels of ozone reach unhealthy levels.

The state says that under the new standards, air quality alert days could be designated earlier and later in the year than usual.

State environmental officials are urging residents to limit driving as well as their use of small engines and lawn mowers. High ozone levels can cause coughing, chest pain, throat irritation and shortness of breath.
