Did you see that incredible fog that covered parts of the valley this week? The cold front that passed through the valley on Monday made Phoenix seem more like waking up in Seattle on Tuesday. Moisture from the rain, high dew point, and cool air temperatures left a thick layer of fog during morning rush hour. The fog was so heavy there were even delays at Phoenix Sky Harbor International Airport. The majority of fog was near South Mountain but also in other areas of the state. It began clearing as the temperature rose through the day.

As it is an unusual sight in the Valley of the Sun, many motorists may be unfamiliar with the procedure of this extreme driving condition. Fog can certainly be a factor in car accidents. According to the Arizona Department of Transportation to protect yourself from an accident, slow down and use low-beam lights. Should fog become too thick, drivers should exit the road and wait for it to clear. You should always use caution with extreme weather conditions and abide A.R.S. Sec. 28-701 Reasonable and Prudent Speed wherein:

1. A person shall not drive a vehicle on a highway at a speed greater than is reasonable and prudent under the circumstances, conditions and actual and potential hazards then existing. A person shall control the speed of a vehicle as necessary to avoid colliding with any object, person, vehicle or other conveyance on, entering or adjacent to the highway in compliance with legal requirements and the duty
2. The maximum speed provided in this section is reduced to the speed that is reasonable and prudent under the conditions and with regard to the actual and potential hazards then            existing, including the following conditions:
3. A special hazard exists with respect to pedestrians or other traffic or by reason of weather or highway conditions
