Motorists are advised to take extra caution when driving on the Pacific Highway at Taree as visibility may be affected by smoke drifting from a hazard reduction burn.
The burn is taking place in a State Forest area near Old Bar and is under control.
Motorists are encouraged to slow down, keep windows up and turn headlights on.
Hazard reduction burns are one way of preparing for bushfires.
A program of burns has been undertaken on the North Coast since Easter.
These included Lansdowne, Johns River and Lorne State forests.
Keep up-to-date with hazard reduction burns and bushfires on the Fires Near Me app or www.rfs.nsw.gov.au/fire-information/fires-near-me.
