Mid-ranking gardaí are calling for pedestrians and cyclists to be obliged to wear hi-visibility clothing and helmets.

That is just one of close to 30 motions to be debated by 150 delegates representing over 2,000 sergeants and inspectors gathering in Killarney for their annual Association of Garda Sergeants and Inspectors (AGSI) conference.

Other motions urge the Justice Minister Frances Fitzgerald to introduce the offence of taking footage of gardaí on duty - as well as calling on the Garda Commissioner Noirin O'Sullivan to protect members and their families who are being harassed online.

The official theme of the conference is Modernising the Industrial Relations Landscape, but scandal after scandal hitting the force is impacting on garda sergeants and inspectors.

There is no mention in the conference motions of investigations into whistleblowers, wrongful convictions for penalty points, false breathalyser data or the upcoming root and branch review of An Garda Síochána.

With two motions of confidence concerning Garda Commissioner O'Sullivan before the Dáil this week, the spotlight will be on her when she addresses the conference on Tuesday.

A Fianna Fáil motion on Tuesday is calling for the Policing Authority to review her position, while Sinn Féin's motion of no confidence in the commissioner is tabled for Wednesday.

Minister Fitzgerald, who has repeatedly maintained her confidence in the commissioner, will not be attending the conference.
