The primary concern when driving in adverse weather conditions is adjusting speed and following distance to maintain control. Adverse conditions such as rain, snow, fog, or ice can significantly affect vehicle handling and traction. By reducing speed, a driver can better manage their vehicle's response to slippery surfaces and maintain a safe stopping distance.

Moreover, adjusting your following distance allows for increased reaction time to unexpected stops or movements from other vehicles. This proactive approach is essential to prevent accidents and ensure the driver can respond effectively to the changing road conditions.

The other options do not adequately address the crucial aspect of control over the vehicle. Maintaining the speed limit can be unsafe in adverse conditions if it does not take into account road traction or visibility. Using high beams might create glare in certain conditions, worsening visibility. While driving in the tire tracks of other vehicles may seem useful for better traction, it is not a comprehensive solution for maintaining control in hazardous weather, as conditions can vary significantly from the tracks to the surrounding areas.
