Drivers are being urged to take extra care on the roads as farm machinery and trucks mobilise for another big harvest across regional NSW.

Parkes, Forbes and Lachlan Shire Councils' Road Safety and Injury Prevention Officer, Melanie Suitor, said the bumper harvest will mean there are more trucks and farm machinery on the roads as well as a surge in activity on level crossings where trains are not often seen.

“It’s looking like this harvest is going to be one of the biggest we have had in our region for a number of years.  We need to remember how busy our local roads are during harvest.

“When approaching an oversize vehicle you should: be patient, reduce your speed and wait for a safe opportunity to pass.  Don’t drive right behind the farm machinery because the operator can’t see you.

"Trucks may also have trailers attached and can be longer or wider than expected, so drivers need to take extra care when changing lanes and should not try and overtake until it is safe.

"Trains can weigh up to 500 tonnes, travel up to 160 kilometres per hour and are unable to swerve or turn, so obey the level crossings as trains will be running on lines where they are rarely seen," Ms Suitor said.

An awareness campaign run by the Councils' in partnership with Transport for NSW is promoting sharing the road safely this harvest with fold down grain truck warning signs positioned along key harvest routes and at silos and a radio campaign to remind drivers what to do when they encounter farm machinery on the road.

“Fatigue is still one of the biggest killers on our roads and after long days harvesting and transporting grain, farmers and grain transporters need to ensure they are managing their fatigue.

“Ensure you are well rested and if you feel tired while driving, pull over in a safe place and have a rest. We want everyone to get home safely this harvest," Ms Suitor said.
