Instructions in this archived message

Motorists should not drive into a dust storm. PULL ASIDE STAY ALIVE! Dust storms lead to dangerous driving conditions with visibility reduced to near zero. If driving, avoid dust storms if possible. If caught in one, pull off the road, turn off your lights and keep your foot off the brake. There is no safe place on a highway when a dust storm hits. Visibility can be lost immediately, making it difficult or impossible to slow down and avoid stopped vehicles. Delay travel, or safely exit the highway before the dust storm arrives.
