 Tip of the Month: Driving in Snow

Groundhogs Day was February 2nd, and from what I heard there was a prediction of an early spring.  I think Mother Nature heard too.  So she decided to take advantage of the time she had left and drop off some snow.   And boy did we get a good amount of snow.  Since all of this snow has been received over the last several days, the Road Crews have been working hard to try and keep up with making the roads safe for travel.   With that in mind, I thought it would be a good reminder to share some tips about driving in the snow.   

Driving Tips
When driving in Snowy or Icy conditions, look further down the road to be aware of what's coming up ahead.  This will you give you the opportunity to anticipate what is coming, make a decision and hopefully provide the time you need to respond.  

2. Increase your following distance from 3-4 second, to 8-10 seconds to allow more response time.  Double the stopping distance when the roads are wet and triple it when roads have snow and even more on ice.   Remember, the larger the vehicle the longer it takes to slow down and stop.   

Pay attention to any flashing lights on your dashboard. If you see the outline of the car with the squiggly lines behind it light up, this is your vehicle telling you that you are losing traction.  If driving in a straight line, then the tires may be slipping. Or if you are turning, you may be starting to slide.  In either situation, ease up on the accelerator and give your tires a chance to regain traction. 

When going up a hill, get your momentum up first to avoid spinning your tires.  Also, don't stop on a hill.  You may lose your momentum and could end up sliding down the hill.

If you have AWD or a 4x4, remember you may have better traction for acceleration but not necessarily for stopping.  Expect your vehicle to react the same as any "normal" vehicle on the road. 

And finally, if you can, stay home.  Even if you are a good driver, avoid the roads and enjoy the snow from safety of your home. 

With these kinds of conditions you definitely want to remember to slow down and take your time to reach your destination.  Leave earlier, drive slower, accelerate slower and do not use cruise control.  Should you end up behind a snow plow, de-icing truck or sanding truck, give them a little extra room and be patient.   

Finally, remember; Be Prepared, Stay Alert and Be Safe!
