Driving safely in winter

Gritting the roads

We spread salt on roads to prevent ice forming on every night when icy or frosty conditions are forecast.

  • Suitable winter footwear
  • Blanket or sleeping bag
  • Torch and extra batteries, or wind up torch
  • Shovel, Tow chain or rope
  • Windscreen scraper, Jump leads, Mobile phone and batteries

Make your home safe for winter

Prepare to survive in your home on your own, without outside help, for at least three days. Assemble a disaster supply kit and be sure to include winter specific items such as rock salt to melt ice and sand to improve traction, snow shovels or other snow removal equipment. Keep a stock of food and extra drinking water.

If your house could be isolated, here is some useful advice:

  • Have sufficient heating fuel, as regular fuel sources may be cut off, as well as emergency heating equipment plus sufficient fuel for it in case electricity is cut off, such as a portable gas fire, a wood burning stove, a fireplace or a kerosene heater.
  • Keep all heaters at least three feet from flammable objects. Maintain ventilation when using kerosene heaters to avoid a build-up of toxic fumes and always refuel outside.
  • Keep fire extinguishers on hand and make sure everyone in your house knows how to use them. Never burn charcoal indoors.
  • Make sure that your walls and attics are well insulated before winter.
  • During a storm, listen to the local radio or television for weather reports and emergency information.
  • Eat regularly and drink ample fluids, but avoid caffeine and alcohol.
  • Dress for the season with several layers of loose fitting, lightweight warm clothing rather than one layer of heavy clothing. The outer layer should be water repellent. Mittens are warmer than gloves. Always wear a hat, most body heat is lost through the top of your head.
  • Don’t over-exert yourself when shoveling snow, as it can bring on a heart attack.
  • Watch for signs of frostbite: loss of feeling and white or pale appearance in extremities. If symptoms are detected, get medical help immediately.
  • Watch for signs of hypothermia: uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness and apparent exhaustion. If symptoms are detected, get the person to a warm location, remove any wet clothing, warm the centre of the body first, and give warm non-alcoholic beverage if victim is conscious. Get medical help as soon as possible.

Clearing ice and snow

Anyone can clear ice and snow from the pavement outside their home or public spaces to prevent trips and falls.

Don't be put off clearing paths because you're afraid someone will get injured. Remember, people walking on snow and ice have a responsibility to be careful themselves. It's unlikely you'll be sued or held legally responsible for any injuries if you have cleared the path carefully.
