Transport NSW and NSW Rugby League have partnered to launch the Knock On Effect campaign aiming to bring positive messages to the community through rugby league and road safety.

The campaign is part of the state government's Towards Zero campaign to reduce fatalities and casualties on country roads.

Country Rugby League (CRL) western region manager, Peter Clarke, said the former Origin players will help coaches deliver a skills and drills clinic and present the Knock on Effect seminar and road safety message while at Narromine.

"It's aimed at bringing the road toll down to zero and get people to understand the importance of road safety," Clarke said.

"[The players will be there] with some information about consequences and how it effects one's life and their family, if there is the is a tragedy in the family that comes about as a result of an accident."

The campaign features NSW Blues coaches Greg Alexander and Brad Fittler who promote an emotional road safety message after the former's brother, also a Penrith Panthers player, Ben Alexander died in a drink-driving accident in 1992.

The campaign demonstrates how profound the impact a single decision can have a 'knock-on effect" on an entire community.

There will be two sessions on Thursday, with juniors getting the chance to have some fun and mingle with the rugby league stars at Noel Powell Oval, before a seniors clinic at Cale Oval which will focus on the main message of road safety. While the clinic is aimed at 15-year-old people who are about to receive their learners licence, it's open to everyone.

"We want to share the message and try to encourage care and safety around the roads as much as we can," Clarke said.
