This winter has been particularly bad in regards to weather and road conditions. Some highways have been almost impassable, while other major highways and roads have been closed to to the amount of snow. If you come across a road covered in deep snow, or especially drifted snow, avoid driving on it at all costs. Snow drifted in by the wind tends to be hard packed, where as snow that has just fallen tends to be light and fluffy. Drifted snow in many cases can actually support the weight of a full grown man walking in it. If it’s packed that densely, there is no way you’ll be able to drive through it.
It should go without say, that you should never, under any circumstances bypass a barrier stating the road is closed. It’s bad enough if you happen to be in a highway when they close it, but knowingly entering a closed road or highway is never a good idea. If you do, and you find yourself stuck, or in any kind of distress, emergency services may not be able to come to your assistance. Even if they are able, and do come to your rescue, the fines are quite steep, and if you happen to be involved in a collision, your insurance provider may not cover the costs. As you approach a snow covered road, if you even THINK you might get stuck on it, do not drive on it. Better to wait it out, than get stuck in deep snow, where you could be waiting a long time for rescue. Always better to be safe than sorry.
