Fog or low clouds limit visibility and can cause travel delays by car and air. About 20% of vehicle crashes are weather-related each year, according to the U.S. Department of Transportation. Most ...
However, visibility is often reduced somewhat by air pollution and high humidity. Various weather stations report this as haze (dry) or mist (moist). Fog and smoke can reduce visibility to near zero, making driving extremely dangerous. The same can happen in a sandstorm in and near desert areas, or with forest fires.
Behind the driver, cargo, headrests, and additional pillars may reduce visibility. Proper adjusting of mirrors and using other technical solutions can eliminate or alleviate vehicle blind spots. A no zone is one of several areas around a large truck, where the truck driver cannot see. [4] Collisions frequently occur in no zones.
Whiteout or white-out [1] is a weather condition in which visibility and contrast are severely reduced by snow, fog, or sand. The horizon disappears from view while the sky and landscape appear featureless, leaving no points of visual reference by which to navigate.
The U.S. government's road safety agency is investigating Tesla's “Full Self-Driving” system after getting reports of crashes in low-visibility conditions, including one that killed a pedestrian.
The vehicle obtains information, such as facial patterns, steering movement, driving habits, turn signal use, and driving velocity, to determine if the driver's activities correspond with drowsy driving. [17] If drowsy driving is suspected, the vehicle will typically sound off a loud alert and may vibrate the driver's seat. [17]
As a result, average driving speeds on public roads and highways are reduced by up to 40% while heavy snow is falling. [8] Visibility is reduced by falling snow, and this is further exacerbated by strong winds which are commonly associated with winter storms producing heavy snowfall.
A multi-vehicle pileup during a snow squall, causing hazardous driving conditions, has closed a Canadian highway and prompted a significant emergency response. 1 dead, 11 hurt as snow squall leads ...
