Final answer:
The false statement about winter driving is that chains or snow tires make it safe to drive at normal speeds on icy or snow-covered roads. Instead, they should still be used with caution and at lower speeds. more friction on surfaces like icy roads, while salt is spread on icy roads to lower the freezing point of water and reduce ice formation.
Step-by-step explanation:
The statement about winter driving that is FALSE is: D. Chains or snow tires make it safe for you to drive on ice or snow-covered roadways at normal speeds. This statement is incorrect as chains or snow tires improve traction but do not eliminate the dangers of sliding or losing control on icy or snowy surfaces, and one must still drive at reduced speeds.
Regarding friction, snow tires are designed to create more friction on icy roads compared to summer tires. Another example where more friction is desirable is with sports shoes, such as cleats used in football or soccer, which provide athletes with the necessary grip on grassy or muddy surfaces to prevent slipping, thus enhancing performance and safety.
Adding salt to icy roads is an example of lowering the freezing point of water, which makes it more difficult for ice to form and easier for it to melt, thus reducing the hazard on the roads. This is known as the freezing point depression and is a reason why colder climates use salt in winter road maintenance.
