When visibility turns bad

... driving in fog


Photo of cars in fogDO:

* 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. They could save your life.

* 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 the 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 protected area from other traffic. Turn on your emergency flashers.


DON'T:

* 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:

Before you drive, and during your trip, check weather forecasts and road reports. If there is a weather warning or reports of poor visibility and driving conditions, delay your trip until conditions improve, if possible.
