I’ve only been driving in Ireland for several days, so less than 100% of the iconography of the signage makes sense to me instantly, for now. But this one’s a complete mystery to me.
Is this warning joggers than tiny cars might bounce off their heads? Or is it exhorting distant swerving motorists to put on their right indicator to tell people which way to run to avoid being hit by them? Or maybe it’s advising that down this road is a football pitch for giants and they’ll play “headers” with you in your car if you’re not careful? I honestly haven’t a clue.
