Police are calling for anyone who may have seen cases of "reckless driving" on the Oxley Highway over the weekend.
Two cases of "erratic" behaviour on the roads have been reported to police, where the actions of vehicle's occupants scared other road users enough to warrant calling it in.
One case is being handled by detectives in Gunnedah, after an alleged intimidation incident near Carroll on Saturday.
It's alleged several people got out of the erratically driven vehicle and approached the other car before the concerned driver took off.
If anyone has experienced any incidents call police or triple zero straight away - report it, make a record, and we will investigate matters and cross reference with similar incidents as they occur in that area.Detective Acting Inspector Jason Darcy
Another case is being investigated by officers in Walgett, after a similar experience was reported on the same day near the Burren Junction.
While two cases have been officially reported, three stories have been circulating on social media detailing similar experiences in the area.
Oxley Detective Acting Inspector Jason Darcy is urging anyone who has witnessed this behaviour to report it to authorities.
"Its early stages at this time, and we are following up all inquiries at this moment," he explained.
"If anyone has experienced any incidents call police or triple zero straight away - report it, make a record, and we will investigate matters and cross reference with similar incidents as they occur in that area."
He is also calling on anyone with dashcam footage to come forward and assist with their inquiries.
"We are currently reviewing CCTV footage, and are appealing for persons with dashcam footage who were travelling Oxley Highway at that time."
