Revision material from the imported DVSA bank includes source-checked Lanekind learning corrections. These corrections are not newly issued official examination questions, and practice does not reproduce a live test paper.

Using a tyre with a recut tread

Using a tyre with a tread depth of 1.3 mm

Using a tyre with exposed ply or cord

Show the answer

Using a tyre with exposed ply or cordThis was the right answer

Exposed ply or cord is a dangerous tyre defect. The minimum heavy-vehicle tread standard differs from the 1.6 mm car and light-van requirement, so the question is explicitly about a vehicle over 3.5 tonnes. Recut tyres must be suitable and lawfully regrooved, not improvised.
