Block Gear Changing | Learning to drive: Car Control skills


-GB Block, or selective gear changing is a modern technique that can save time when changing speed in a car with a manual gearbox. In the past, drivers were taught to change down gears sequentially as they slowed their car down – primarily to avoid overheating their brakes. Now that modern cars have much better braking systems we don’t need to do this, and can miss out gears at the appropriate time. This gives us more time to concentrate on the road ahead, and to keep our hands on the steering wheel for longer. In this video we will show how to block change gears, and where it can be useful.
Imagine we are driving at 40mph in 4th gear, and need to slow down to 20mph as we approach a roundabout. We could change from 4th to 3rd, and then into 2nd. Or we could block change directly from 4th gear into 2nd gear, and miss out 3rd gear altogether, as it is not useful to us. Reducing unnecessary gear changes like this saves the driver time, and can even reduce wear on the clutch and gearbox. As a general rule we should use the brakes to reduce our speed, before changing down to the most suitable gear for the lower speed. Block changing is most useful when we are slowing down quickly, as we might not have enough time to change through every gear sequentially.
