IV. Driving at night and in bad weather
Tips for safe driving in fog

Before you drive — and during your trip — check weather forecasts. If there is a fog warning, delay your trip until it clears. It could save your life. If you are caught driving in fog, follow these safe driving tips:

DO:
  • Slow down gradually and drive at a speed that suits the conditions.
  • Make sure the full lighting system of your vehicle is turned on.
  • Use your low-beam headlights. High beams reflect off the moisture droplets in the fog, making it harder to see.
  • If you have fog lights on your vehicle, use them, in addition to your low beams.
  • Be patient. Avoid passing, changing lanes and crossing traffic.
  • Use pavement markings to help guide you. Use the right edge of the road as a guide, rather than the centre line.
  • Increase your following distance. You will need extra distance to brake safely.
  • Look and listen for any hazards that may be ahead.
  • Reduce the distractions in your vehicle. For example, turn off your cell phone. Your full attention is required.
  • Watch for any electronically operated warning signs.
  • Keep looking as far ahead as possible.
  • Keep your windows and mirrors clean. Use your defroster and wipers to maximize your vision.
  • If the fog is too dense to continue, pull completely off the road and try to position your vehicle in a safe parking area. Turn on your emergency flashers, in addition to keeping your low-beam headlights on.

DON’T:

  • Don’t stop on the travelled portion of the road. You could become the first link in a chain-reaction collision.
  • Don’t speed up suddenly, even if the fog seems to be clearing. You could find yourself suddenly back in fog.
  • Don’t speed up to pass a vehicle moving slowly or to get away from a vehicle that is following too closely.
REMEMBER:
  • Watch your speed. You may be going faster than you think. If so, reduce speed gradually.
  • Leave a safe braking distance between you and the vehicle ahead.
  • Remain calm and patient. Don’t pass other vehicles or speed up suddenly.
  • Don’t stop on the road. If visibility is decreasing rapidly, pull off the road into a safe parking area and wait for the fog to lift.
  • Use your low-beam lights.
