A terrifyingly big bolt of lightning was caught on dashcam as it cut across the whole visible sky during a nighttime storm in Sydney, Austalia.

The slowed-down footage shows the moment frame-by-frame as the fork of electricity goes from right to left across the whole sky.

Network engineer Bhagirathsinh Sisodiya, 39, was driving home through the suburbs when he caught the flash on January 3rd.

Bhagirathsinh was driving down Hawkesbury Road in the suburb of Westmead.

He said: "As I saw this fantastic lightning, I saved the footage.

"It was massive lightning covering almost the whole horizon."
