The poster highlights the danger of a vehicle entering the lane of oncoming traffic to overtake another vehicle. The manoeuvre is being done just before the dip of a hill which makes it even more dangerous since there’s no way of seeing the oncoming traffic. The ‘Journey’s End!’ tagline emphasises that this journey isn’t going to end well and the motorcyclist is going to suffer more than just a personal injury!
