Which statement about tire chains is true?

• A. They are decorative and not safety-related
• B. They should be installed on just one tire
• C. They are used to improve traction; required when posted or when conditions require; install as directed by authorities
• D. They are never needed

Answer: (C)

Tire chains are a safety device used to gain traction on snowy or icy roads. They should be installed whenever road signs require them or when conditions demand extra grip, and you must follow the instructions provided by authorities or posted signs. Chains work by digging into packed snow and ice, giving your tires a better grip so you can maintain control and continue safely. They aren’t for decoration, they aren’t meant for just one tire, and there are times when they’re not needed if conditions improve or alternatives are allowed by law. In practice, you’ll install them on the drive wheels as directed and remove them when signs no longer require them or when there’s clear pavement.
