MOVES to install interactive warning signs on the Holy Island causeway will be seen as a step in the right direction by many people.
But the question remains, whether the handful of reckless motorists who dice with death each year by ignoring safe crossing times will obey them.
The route is already festooned with a barrage of notices, some showing dramatic images of cars submerged almost to their roofs by the tide. Yet more than 20 drivers in the last year alone chose not to heed them and paid the inevitable price of their cars being swallowed by the sea.
Signs, it has been proven, can only go so far in deterring risk-takers. Aside from an actual physical barrier preventing access to the causeway at high tide, there is nothing to stop someone who is determined enough to take a chance.
Barriers, apart from being lambasted by islanders as unnecessary and perhaps even dangerous, are fraught with problems, not least the effects of wind, sand and salt water.
That leaves few alternatives as a means of barring access when nature intervenes.
One oft-repeated suggestion is to prosecute those who wilfully ignore the warnings – particularly given the enormous cost of rescuing them from the elements.
This itself gives rise to concerns that a foolish, stranded motorist would not contact the emergency services for fear of being hauled before the courts.
Let’s hope the new signs work, for everyone’s sake, and solve this problem.
