Here's why it pays to be alert and go slow when on the road

A motorcyclist nearly collided with a lorry, but fortunately managed to stop in time and avoid a nasty accident.

A video posted by Motorist.sg on Facebook shows how the lorry had been switching to its left lane just as the biker approached.

Thankfully, the motorcyclist reacted quickly by slowing down and allowing the lorry to pass first.
