Cevap

The driver must reduce speed to a rate that is safe for the reduced visibility conditions, regardless of the posted speed limit.
The Basic Speed Law states that no person shall drive at a speed greater than is reasonable or prudent having due regard for weather, visibility, traffic, and surface conditions. In thick fog with low visibility, driving at the posted maximum is unsafe and illegal.

Heavy fog restricts visibility to under 50 feet50\text{ feet}.
Severe weather impairs stopping sight distance.
2
Apply the Basic Speed Law requirement
Determine that the posted limit of 55 mph55\text{ mph} is no longer safe.
The Basic Speed Law requires driving at a reasonable speed for current road and weather conditions regardless of posted signs.
