Prepare for a video-load of adorable...

When a family of black bears tried to cross a busy motorway in Canada at the weekend, one of the cubs got stranded in the line of traffic as it was too small to climb over the roadside barrier.

Cue Mother Bear to the rescue.

Video footage shows cars whizzing by metres from the helpless youngster as its mother carefully looks both ways before using her mouth to hoist the cub to safety.

Meanwhile, another of her cubs is seen jumping up onto the barrier to see what all the fuss is about.

The amazing scenes were captured by Ricky Forbes, a tornado hunter (yes, that is a job).

He posted the video on YouTube, explaining how he came to spot the touching scene:

"Driving through British Columbia's Kootenay National Park we stopped to capture a shot of a baby bear on the highway only to get much more of a show.

"While watching the cub we saw the mama bear stick it's head over the barrier to save it's young from its dangerous predicament. It almost looks like she looks both ways first! A very amazing sight to see."
