Revision question · Vehicle condition

What risk can sustained motorway-speed driving increase if tyres are under-inflated or damaged?

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.

They'll be more likely to overheat and disintegrateThis was the right answer

Under-inflated tyres flex excessively and can overheat, deteriorate or rapidly deflate during sustained use. Check cold pressure for the load and inspect damage; correct tyres are designed for their rated speed, so disintegration is not a normal inevitable result of motorway travel.
