An insulated vehicle has a mechanical-compression or absorption refrigeration unit that lowers and maintains its body temperature. Which specific vehicle classification applies?

Correct answer

Mechanically refrigerated: with mechanical-compression or absorption refrigeration.

Mechanically refrigerated (frigorífico) under Annex II of the General Vehicle Regulations. It combines an insulated body with a mechanical-compression or absorption refrigeration unit. A non-mechanically refrigerated vehicle (refrigerante) uses another cold source; insulation alone limits heat transfer through insulated walls. Although a frigorífico is also insulated, the question asks for its specific classification with refrigeration equipment rather than that general property.
