This overall aim of this unit is that the driver should be able to guide and control their vehicle safely and responsibly, taking into account road, traffic and weather conditions. This unit is based on the understanding that driving is a complex task; it involves taking in a large amount of information and responding to it appropriately. To be able to do this a driver must be able to constantly scan the world around them, understand what is happening and identify possible hazards and risks. A key part of being able to manage this complexity is the ability to master basic driving skills, such as steering and coordinating the use of controls, so that the driver does not have to think about doing them. Acquiring these skills will provide a driver with the basic blocks on which they can then build. It is important, therefore, that they work through any factors or issues that are getting in the way of their learning. It is also important that they get as much supervised practice as they reasonably can. Accompanying drivers can play a vital part in this process. Although a learner may not experience towing a trailer or caravan while they are learning they will be able to do so when they pass their test (within the restrictions of the licence category). It is important, therefore, that they understand the principles.
