When driving on packed snow, it is essential to reduce speed to maintain control of the vehicle and to react appropriately to any changes in road conditions. While the choice that suggests reducing speed by half can be a practical approach, the core idea is that adjusting your speed must be significant to account for the slippery conditions that packed snow creates.

Driving on packed snow can lead to decreased traction, which increases the likelihood of skidding or losing control. By reducing speed by a substantial amount, a driver can increase their reaction time to unforeseen obstacles or maneuvers that may be necessary due to road conditions. This adjustment not only helps with maintaining control but also enhances safety for the driver and others on the road.

The other options imply either a minimal reduction in speed or an immediate stop, which may not be practical or safe in every situation. A gradual adjustment and reduction to a safe speed allows for better control over the vehicle while still enabling forward progress in winter driving conditions.
