A Victorian woman who hit a cyclist as she was turning into a left-hand turn lane has shared the footage as a warning to others.

Simone Jones said the accident happened on Friday. The video was uploaded in Panton Hill, approximately 32km northeast of Melbourne, but it is unclear where the accident had occurred.

In Ms Jones' dashboard camera footage, shared to Dash Cam Owners Australia's Facebook page , the cyclist can be seen crossing the road and attempting to merge into the same lane as Ms Jones.

The front driver's side of her car hit the cyclist, after he appears to have failed to check whether any oncoming traffic was approaching as he merged into the left-turn lane.

"Bad concussion and bruising to his back and limbs," Ms Jones wrote.

She also claims the cyclist's helmet was split in half and his bicycle was damaged.

One commenter was quick to point out that the cyclist is lucky Ms Jones was paying attention and braked when she did.

"He should be thankful you were paying attention," Philip Greenaway wrote.

Ms Jones claims the cyclist expects her to pay for damage to his bicycle and medical bills.

"Old mate thinks that it will all be going through our insurance and doesn't have to pay a thing," Ms Jones wrote.
