The rain greatly reduces adhesion and does not do so uniformly, but at least it is possible, in most cases, to perceive that reduction of adhesion. The snow, and especially ice, are much more unpredictable. The reduction of adhesion is dramatic, and with an intensity that is random.
With a small variation of temperature in the asphalt, the surface goes from being fragile to be a real skating rink, in a very few meters and if able to perceive the difference on a visual level. This is because the difference between the ice and the snow is simply a matter of temperature, and with a few degrees less causes the formation of an ice sheet that, if there has been a snowfall later is hidden.
On the road there are stretches that can or should be put on alert when the formation of ice sheets is possible by sub-zero temperatures. This sections are; wooded areas, close proximity parallel to a river, shady areas that are sometimes not even the sun is coming in all day and above all, bridges on any type of slope, as the air pass underneath the road, will go down in a very noticeable way the temperature leading to the dreaded ice sheets.
With snow on the road we must take extreme precautions
When the nevada is very persistent and begins to build up thickness, the step of the vehicle is formed footprints or ruts that must be our guide. We must try to always drive at the top of these ruts without leaving. The advantage that we have is that the passage of other vehicles tamped the snow and provides a grip even more, any change in acceleration can cause wheel spin and we complicate the advancement.
are able to move by a road nevada without the need of putting chains as long as you keep a number of precautions. The first thing we need to do is to keep a low speed but even, using the highest gear that is possible in order not to cause the wheel to “skid”, and let us drown in the snow.
If we are going to tackle a slope, we must choose the highest gear in which we believe that we can climb up, avoiding the change of motion during the ascent. In these conditions, it may be appropriate to disconnect the control of stability, for which the possible and minor landslides do not act and force us to speed up with more decision, which would result in more loss of motor skills. Of course, the safety distance in these cases should increase in the double or more, thus avoiding a possible collision with the car preceding.
We need to put the chains on the drive wheels
In any case, the first thing is always safety. If the snow is very heavy it is best to stop and put chains, and in an extreme case, look for the nearest place and safe to stop. If you live in an area where snowfalls are abundant and frequent, it is best to install winter tires.
oddly enough, some drivers do not know where you should put the chains on. Strings the post is always on the driving wheels. We need to be clear that its function is to increase the adhesion longitudinal, allowing us to have traction and braking. Keep in mind that the strings just increase the adhesion side, so that one must be very cautious when taking a curve. As always, the security is the first.
