Arkansas Commercial Driver License (CDL) Practice Test

Reducing your speed to a crawl on icy roads is crucial for maintaining control of your vehicle. When roads are icy, the traction between the tires and the road surface is significantly decreased, increasing the risk of skidding or losing control. At a crawl, you can better navigate the treacherous conditions, allowing for greater reaction time and the ability to stop safely if necessary. The slower speed also helps to minimize the severity of any potential accidents if they do occur. In other scenarios like heavy traffic, light rain, or foggy conditions, although it is important to adjust your speed, reducing to a crawl may not be necessary or safe. In heavy traffic, maintaining a safe following distance and speed with the flow of traffic is typically recommended. Light rain can make roads slippery, but usually does not require a crawl unless conditions worsen. Fog demands careful speed adjustments, but a crawl can hinder visibility for others and create hazards if not needed.
