People are always good at handing out advice, aren’t they?

One particular mother in the US city of Kent, Washington state, gave her biker son a particularly good tip before he set off on the road, telling him to ‘watch out for idiots’.

Seems fair enough, right?

Well, just after her son sets off, he’s rear-ended by some joker in a silver Hyundai.

And who’s behind the wheel of the car? You’ll never guess…

Yup, his mum. Way to go there, Mom!

We think that maybe she should have heeded her own advice on this one.

Check out the full video below. Please be aware, there’s a heck of a lot of swearing.
