Why you should always check your blindspot when changing lanes

A terrifying video has emerged, showing why you should always double check your mirrors and blindspot before you move over on a motorway. The footage, captured on dashcam by a passing vehicle, shows a driver attempting a lane change – only noticing an impending collision at the last minute.

A silver saloon car begins drifting across its lane, seemingly unaware of another vehicle overtaking on its outside. The driver of the silver car finally notices they're about to smash into following traffic, and jerks back into their own lane – but they overcorrect, and are immediately sent into a terrifying spin.
