The best way for a commercial driver to minimize the risk of accidents in inclement weather is by adjusting their speed and increasing their following distance. This approach is crucial because adverse weather conditions, such as rain, snow, or fog, can significantly affect vehicle handling and stopping distances. By reducing speed, drivers not only give themselves more time to react to sudden hazards but also ensure better traction on slippery surfaces.

Increasing following distance is equally important because it allows for more space to stop safely, recognizing that stopping distances can be much longer in bad weather due to decreased tire grip. Adjusting speed and following distance helps maintain control of the vehicle in challenging conditions and provides the driver with more time to respond to unforeseen obstacles or changes in traffic patterns.

Relying on the posted speed limit is not advisable in adverse weather, as it does not account for the changed conditions that may require a slower speed to maintain safety. Using cruise control can be dangerous in wet or slippery conditions, as it may lead to loss of control. While not driving at all eliminates the risk of accidents, it is not a practical solution in all situations and may not be an option for drivers who need to complete their routes. Thus, the most effective strategy involves being adaptable and cautious in response
