Arkansas Commercial Driver License (CDL) Practice Test

In heavy traffic, it is best to maintain the same speed as the surrounding vehicles. This allows for a more consistent flow of traffic and reduces the risk of accidents. Option A, going slower than other traffic, can impede the flow of traffic and cause potential hazards for other drivers. Stopping frequently, as mentioned in option B, is not only impractical but also dangerous for both the driver and other vehicles on the road. Option D, speeding up often, can also be hazardous as it can cause abrupt changes in speed, making it difficult for other drivers to anticipate and react accordingly. Therefore, maintaining the same speed as other traffic is the recommended driving speed in heavy traffic.
