As the cooler weather of fall and winter seasons arrive,

we will see increase numbers of days with reduced visibility due to fog.

`

Fog is a thick cloud of microscopic water droplets suspended at ground .

It often occurs in the evening or morning when the cooling ground brings the air temperature down to dew point, and vanishes in the morning with the heat of the sun.

CHARACTERISTICS OF

Fog produces a combination of wet, slippery pavement and reduced visibility.

Adverse visibility conditions dramatically increase the

risk of chain reaction accidents.

Fog promotes accidents by means of “Aerial perspective,"

A visual effect which causes people to misjudge distance.

We see objects, not based on their absolutebrightness or darkness, but on their difference between the object brightness and background.

Normally the driver has an expectation that cars do not stop on freeways. The driver may then fail to realize

that the car ahead is stopped until it is too late

.

Fog lowers contrast substantially, causing objects to become fainter and less distinct.

Faintly seeing a car ahead will be very difficult to detect that it has stopped because the lower contrast impairs speed

judgments.

Fog causes the driver to underestimate his/her own speed which leads to the horrific

chain reaction accidents

Fog obviously produces accidents because driver cannot see as far ahead.

the following tips can help reduce the

risk of a crash.

Start early and always wear your seat belt.

Reduce speed and Maintain sufficient distance in between vehicles

so that you can stop safely within the distance you can see.

FOG LIGHT

Switch on fog lights if available

Remember : Fog lights are designed for special weather conditions and unnecessary use of it is not only illegal but dangerous as well.

Use low-beam lights to see and be seen.

Do not use high beam lights.It’s quite natural to switch to high beams so that you can see further. In fact, the main effect is to scatter more light back to the eye and actually decrease visibility by using high beam lights.

Do not use the emergency lights while driving

To avoid confusion at the time of turning to Left or Right.

Try to avoid unnecessary lane changes.

Try to avoid over taking vehicles.

Avoid sudden stops and turns. Signal your intentions well in advance.

Use the windshield wipers and defroster to keep the windshield clear

Pull off the road as far as possible and stop if visibility is too poor

Turn on the emergency lights.

Dense fog can drastically impair visibility, So while working in the foggy area take

additional care tojudge the way you pass to avoid any

possible hit with objects.
