Technical roadworthiness tests of vehicles have the objective to ensure that vehicles are maintained in the safe and environmentally friendly state during their exploitation. The system includes regular and periodic roadworthiness tests that are performed at roadworthiness testing centres, as well as roadside inspections. In the Republic of Croatia, regular technical roadworthiness tests and periodic technical roadworthiness tests are mandatory for buses, lorries and trailers with a maximum authorised mass exceeding 7 500 kg, where roadworthiness tests are mandatory every 12 months, and periodic technical roadworthiness tests depend on the age of vehicles. Vehicles that are from 2 to 7 years old have to be periodically tested every 6 months, and vehicles older than 7 years have to be tested every 3 months. In 2014, 34 290 lorries and buses and 17 461 trailers with a maximum authorised mass exceeding 7 500 kg underwent regular technical roadworthiness tests. The technical deficiency was established on 23.4% of buses, 24.2% of lorries and 14.8% of trailers. There were 61 906 periodic roadworthiness tests executed on vehicles of the same category ; technical faults were established on 27.9% buses, 23.1% lorries and 22.3% of trailers. On the other hand, during roadside, technical roadworthiness tests for that vehicle category, highly alarming rate of more than 70% of deficiencies was established. The objective is to establish the real share of malfunctioning buses, lorries and trailers with a maximum authorised mass exceeding 7 500 kg on the road and, based on those results, to adopt scientifically based recommendations for frequency of regular and periodic roadworthiness tests. Within this research, the results of regular tests, as well as the results of randomly picked vehicle target categories on the road, were analysed in detail. When it comes to regular and periodic roadworthiness tests, the deficiencies are on the level of about 25% of the cases, while roadside inspections established deficiencies in 48% of the cases. The conclusion is that the vehicles in regular circulation have practically two times higher level of deficiencies than the vehicles that regularly undergo regular and periodic roadworthiness tests. |
