"Treading" On Thin Ice!

Two vehicles went through the ice last weekend but it happens every year and more often each season.

I saw in the news last night that a couple of vehicles had been out on the Ghost Reservoir, about 45 km west of Cochrane, and had fallen through the ice. Although no-one was hurt and neither vehicle was completely submerged, it raised questions about personal safety and environmental concerns, what with oil and gas from the vehicles potentially polluting the reservoir.
In an interview with a local resident, the point was made that it happens far too often, seemingly with multiple incidents occurring every season and getting worse with each passing year.  They asserted that there seems to be no control over who can get out on the ice, in what type of vehicle, not to mention when this is or is not safe and who is responsible for making the determination.The reservoir is under the care and control of Alberta Provincial Parks as a Recreation Area but without 24 hour monitoring, common sense should prevail, although the latter is evidently not so common..
We know it's a popular spot for ice bike racing, ice fishing and ice sailing, all of which involve only a few hundred kg of weight. It's a shame to think that these activities may be threatened as a result of a couple of people rolling out on the ice in a 1000 kg + vehicle who not only risk their own lives but also those who are responsible for rescuing them, should the incident ever escalate to that point.
Not that it's any guarantee for your safety but here's a handy guide that may help you make a better determination on when it is safe, should you ever have to actually drive on ice.
