A cyclist has been slapped with a fine after claiming he has footage of a car illegally overtaking him.

Dashcam footage from the incident on August 9th was posted to the Facebook page Cycliq, which is a company that sells light and camera safety systems to cyclists.

The video appears to show the car drive close to the cyclist as the car tries to overtake the cyclist as they were both travelling down a hill.

Under NSW road rules, drivers must leave at least a metre of space when the speed limit is 60kmph or 1.5m when the speed limit is more than 60kmph.

However, the cyclist took the video to NSW Police only to be hit with a fine for travelling too far from the left-hand side of the road. 

“Took this to NSW Police and I ended up getting booked for not riding as near to left of the road as possible,” he wrote.

“Descending down an unguttered road with blind driveways at 50kph, and I was as close to the left of the road that was safe in the circumstances.

“It seems NSW Police intent on keeping road as perilous as possible for cyclists.”

The fine was $116.

Cycliq commented on the incident, saying that the decision was a "very sad indictment on the attitude of the NSW Police Force".

“Change is happening whether they like it or not, and they are going to have to catch up with the times because the videos won’t stop coming and the pressure will only build,” it said.
