Final answer:
When driving on packed snow, it is recommended to reduce your speed by 30%. This helps compensate for reduced traction and lowers the risk of skidding.
Step-by-step explanation:
When driving on packed snow, it is recommended to reduce your speed by 30%. This is because packed snow reduces traction, making it more difficult to control the vehicle and stop quickly.
Reducing your speed by 30% can help to compensate for the decrease in traction and minimize the risk of skidding or losing control of the vehicle.
