In Italian traffic rules (Codice della Strada), what is the rule regarding the minimum legal tyre tread depth for passenger cars (autovetture) under the Italian Highway Code?

Answer and explanation

Correct answer: B. 1.6 mm across the entire principal tread pattern

  1. Step 1: Under Appendix VIII to Art. 237 of the Codice della Strada, the minimum legal tread depth is 1.6 mm for cars, 1.0 mm for motorcycles, and 0.5 mm for mopeds. Answer: 1.6 mm across the entire principal tread pattern. Why not the others: the other options do not conform to Italian traffic regulations under the Codice della Strada.
