With temperatures predicted to plummet this weekend and the potential for a major snowstorm in the forecast, AAA is encouraging drivers to understand the impact of these extreme conditions on their vehicles and homes — and prepare accordingly.
Know How the Coldest Temperatures Affect Vehicles
Freezing temperatures can negatively impact vehicle performance in several ways, including:
- Drained batteries: A typical battery requires 30% more power to start a vehicle when the temperature reaches 32 degrees. Additionally, a battery can lose up to 50% of its capacity when the temperature approaches zero degrees. This combination of cold-diminished batteries requiring more energy to start a vehicle is why many cars fail to start during cold snaps. Consider having the battery and charging system tested at an AAA Approved Auto Repair facility if your battery is older than three years old or you’ve noticed recent difficulty starting your vehicle in the cold. If you have a dead battery and need a replacement, AAA members have access to mobile car battery replacement.
- Decreased tire pressure: Cold also negatively affects tires, which lose about one PSI (pound per square inch) of pressure for every 10 degrees the air temperature drops. Tires also normally lose one PSI per month due to aspiration. Before hitting the road, drivers should make sure tires are properly inflated according to information on the sticker inside the driver’s door jamb.
- Frozen fuel lines: Any moisture in a vehicle’s fuel lines can freeze, preventing gasoline from reaching the engine. Drivers should keep their gas tanks at least half full during the winter so that there will be no room for air or water vapor. If drivers suspect there is water in the fuel tank, they can use a gas line antifreeze.
Stay Safe on the Roads, and Stay Home if You Can
AAA recommends travelers consider adjusting their travel plans, if possible, to avoid driving during or immediately after peak periods of snowfall. If you really don’t have to go out during or right after a storm, don’t! Even if you think you can drive well in bad weather, it’s better to avoid taking unnecessary risks by venturing out. Otherwise, driving in ice and snow requires an adjustment to driving habits:
- Remove snow and ice from their vehicles before driving. This is critical for maximum driver visibility and to prevent blowing snow and ice from possibly blinding other drivers.
- Slow down. Always adjust your speed down to account for lower traction when driving on snow or ice. Curbing your speed provides you with more time to react.
- Accelerate and decelerate slowly. Apply the gas slowly to regain traction and avoid skids. Don’t try to get moving in a hurry and take time to slow down for a stoplight. Remember: it takes longer to slow down on icy roads.
- Increase your following distance. Allow five to six seconds of following distance between your vehicle and any vehicle in front of you. This space allows time to stop safely if the other driver brakes suddenly.
AAA also urges all drivers to keep a cold-weather emergency kit in their vehicles, complete with warm clothing, blankets, extra water and food, extra chargers, an ice scraper and any medications they may need in the event of an emergency.
Protecting Your Home From Winter’s Worst
The frigid temperatures can also bring winter-related damage for homeowners. The most common types of insurance claims related to severe winter weather include frozen pipes, ice dams building up along roof edges, damage from falling trees and limbs and even house fires.
AAA Insurance recommends that all homeowners take these steps to effectively winterize their homes for safety and to avoid costly repairs:
- Clear gutters and downspouts of debris to allow melting snow and ice to flow freely. To help prevent ice dams from forming, keep the attic well-ventilated and the attic floor well-insulated. Heat tape may also help prevent ice buildup and can facilitate melting.
- To prevent pipes from freezing and bursting, insulate exposed pipes, seal cracks in outside walls near pipes, keep cabinet doors on exterior walls open and keep a slow trickle of water flowing through unprotected pipes during cold spells.
- Know the location of the main water shutoff valve: If your pipes freeze, the faster you shut off the water, the better chance you have of preventing them from bursting and causing major damage.
- Ensure your heating system is up to snuff by having the furnace, boiler or chimney serviced at least once a year. Be sure to have ducts, vents and filters inspected.
- Check your smoke and carbon monoxide detectors: Residential fires and carbon monoxide poisonings increase in the winter as people rely on indoor fires and heating systems. Detectors should be checked at least twice a year.
- Follow all safety guidelines when using supplemental space heaters to prevent electrical fires or fires caused by the placement of heaters too close to flammable materials.
- Trim trees and remove dead branches: Ice, snow, wind and rain can cause weak trees and tree limbs to fall and damage your car or home – or fall on people walking on or near your property.
- Clear your driveway and walkway of snow as soon as possible to prevent slips and falls.
