1.For each item to be tested, Annex I provides a minimum list of possible deficiencies and their level of severity.
2.Deficiencies that are found during periodic testings of vehicles shall be categorised in one of the following groups:
(a)minor deficiencies having no significant effect on the safety of the vehicle or impact on the environment, and other minor non-compliances;
(b)major deficiencies that may prejudice the safety of the vehicle or have an impact on the environment or put other road users at risk, or other more significant non-compliances;
(c)dangerous deficiencies constituting a direct and immediate risk to road safety or having an impact on the environment which justify that a Member State or its competent authorities may prohibit the use of the vehicle on public roads.
3.A vehicle having deficiencies falling into more than one of the deficiency groups referred to in paragraph 2 shall be classified in the group corresponding to the more serious deficiency. A vehicle showing several deficiencies within the same inspection area as identified in the scope of the test referred to in point 2 of Annex I, may be classified in the next most serious deficiency group if it can be demonstrated that the combined effect of those deficiencies results in a higher risk to road safety.
