Description
Art. 66 para. 1 pt. 1 of the Act of 20 June 1997 - Road Traffic Act (consolidated text: Journal of Laws of 2012, item 1137, as amended), in conjunction with § 11 para. 7 pt. 4, 5 of the Regulation of the Ministry of Infrastructure of 31 December 2002 on the technical conditions of vehicles and the scope of their necessary equipment (Journal of Laws No. 32, item 262 of 2003, as amended) and § 2 para. 4 pt. 3 of the Regulation of the Minister of Transport, Construction and Maritime Economy of 26 June 2012 on the scope and manner of conducting technical inspections of vehicles and the templates of documents used in these inspections (item 996).
Explanation
Correct answer: 1.6 millimetres.
According to the regulations, the minimum permissible tread depth for passenger car tyres is 1.6 mm. A shallower tread drastically reduces the vehicle's grip, especially on wet surfaces, and significantly increases the braking distance. Driving on worn tyres is dangerous and can result in a fine and confiscation of the vehicle's registration certificate.
