What is the minimum tread depth required on school bus snow tires used in lieu of tire traction devices?

• A. 4/32
• B. 6/32
• C. 2/32
• D. 8/32

Answer: (B)

The minimum tread depth required on school bus snow tires used in lieu of tire traction devices is 6/32 of an inch. This requirement is established to ensure adequate traction during winter conditions, which is crucial for the safety of school pupils being transported. Tires with a sufficient tread depth provide better grip on slippery surfaces, such as snow and ice. Using tires with a depth of less than 6/32 may significantly increase the risk of skidding or losing control of the bus, thereby endangering the safety of the passengers. This standard reflects a balance between safety and performance needed for vehicles operating in adverse weather conditions common during winter months.
