What is the recommended speed reduction when driving on snowy roads?

When driving on snowy roads, it is critical to adjust your speed to account for the decreased traction and visibility that winter conditions bring. Reducing your speed by half of the normal speed limit is a commonly recommended practice because it significantly lowers the risk of losing control of the vehicle. This substantial reduction allows for increased time to react to obstacles, other drivers, and changing road conditions.

Snow and ice can create slippery surfaces that impede braking distances and make steering less responsive. By slowing down dramatically, drivers can better navigate potential hazards and maintain control, ultimately enhancing their safety as well as that of other road users.

In contrast, merely reducing speed by 10-20% may not be sufficient in many snowy conditions, where the risk of skidding or losing control is elevated. Setting a specific speed like 25 MPH could also be inappropriate for all snowy conditions, as it may not be safe in areas where higher or lower speeds are warranted based on road characteristics and traffic. Lastly, maintaining the normal speed limit in snowy conditions is extremely risky and can lead to accidents due to the compromised road surface.
