Tip of the Month:  Prepare Yourself for Winter Driving

Thanksgiving has come and gone and several more holidays are on the way.  Which means, Old Man Winter is here to visit just in time for all of our holiday travel.  He of course brings with him colder temperatures, freezing fog, and the possibilities of ice, sleet and snow.  Keeping that in mind, you will want to alter your driving habits for these conditions.  

When driving, take your time to reach your destination; leave earlier, drive slower, accelerate slower and do not use cruise control.  Leave extra room between yourself and the vehicle in front of you.  Remember, the larger the vehicle the longer it takes to slow down and stop.  

Slow down when approaching intersections, offramps, bridges or shady spots.  These areas could have black ice. Also, don't brake suddenly, as that can cause you to slide.  Finally, if you end up behind a snow plow, de-icing truck or sanding truck, give them a little extra room and be patient.  Remember to be prepared, stay alert and be safe!

For more winter driving tips and information go to the Washington State Department of Transportation's winter section on their website:  On their website is a Winter Driving Guide, a Video on How to Install Tire Chains, What to Carry in Your Car and a Winter Driving Checklist.  All useful tools for the upcoming months.

In an effort to keep the citizens of Benton County informed, upcoming construction projects are posted on the County's Facebook page, you can also find information about closures and detours on the main Benton County website. Pothole repairs, maintenance and other road repairs may slow your drive and, quite possibly, tax your patience. Stay calm, slow down and be aware of the conditions around you. Be especially careful driving through work zones. Increase your following distance and avoid distractions.
