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.
Drive chains wear and need frequent adjustment and lubrication. If the drive chain is worn or slack, it can jump off the sprocket and lock the rear wheel. When you've adjusted the chain tension, you need to check the rear wheel alignment. Marks by the chain adjusters may be provided to make this easier.
