If you do have to travel during the storm, AAA advises to be cautious and offers the following safety tips:

• Check road conditions – Before you leave, assess the conditions of roads along your route.

• Remove ALL snow and ice – It’s the law in Pennsylvania – motorists must remove all snow and ice from their vehicles before returning to the roads; dislodged snow/ice can become projectiles.

• Slow down/increase following distance – Adjust your speed to the road conditions and leave yourself ample room to stop. Allow at least three times more space than usual between you and the car in front of you. Accelerate, turn and brake gradually. Don’t brake and turn at the same time. Asking the car to do two things at once makes it more likely your tires will lose traction.

• Never use cruise control on slippery roads – A driver should always be in full control of their vehicle during poor road conditions and cruise control can misinterpret slipping and sliding as the vehicle slowing down and attempt to accelerate to maintain speed.

• Avoid unnecessary lane changes – This increases the chances of hitting a patch of ice between lanes that could cause loss of vehicle traction. Drive in plowed lanes. If that’s not available, drive in the tire tracks of vehicles in front of you.

• Know your brakes – Whether you have antilock brakes or not, keep the heel of your foot on the floor and use the ball of your foot to apply firm, steady pressure on the brake pedal.

• Control the skid – Slamming on the brakes can make the skid even worse. If you are approaching a patch of ice, brake during your approach. Applying pressure to your brakes while on the ice will only throw you into a skid. If you do start to skid, ease off of the accelerator or brake and steer in the direction you want the front of the car to go.

• Don’t follow behind other vehicles as closely as you would when driving in clear, dry conditions – Your vehicle cannot slow down as quickly on slick roads. Increase following distances to 8 seconds or more and always keep open space to at least one side of your vehicle, in case you need make an emergency lane change maneuver.

• Don’t be rough with your steering, acceleration and braking – If you are not gentle with steering, acceleration and braking, your vehicle’s balance can be negatively affected, increasing the chance of experiencing a skid. Always steer, accelerate and brake smoothly.

• Don’t stop if you can avoid it – There’s a big difference in the amount of inertia it takes to start moving from a full stop versus how much it takes to get moving while still rolling. If you can slow down enough to keep rolling until a traffic light changes, do it. Be aware of traffic ahead and slow down even more if you start to see brake lights or fish tailing cars.

• Do not power up hills – Applying extra gas on snow-covered roads may only result in spinning your wheels. Try to get a little inertia going before you reach the hill and let that inertia carry you to the top. As you reach the crest of the hill, reduce your speed and proceed downhill as slowly as possible. Don’t stop on a hill as you may not be able to get the vehicle moving again.
