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.

Large vehicles can throw up a lot of spray when it's wet. This makes it difficult for drivers behind to see the road ahead. You'll be able to see more by dropping back further, out of the spray. This will also increase your separation distance, giving you more room to stop if you have to.
