1. A key difference between driver distraction and driver inattention in general is that driver distraction is caused by an event that directs the focus of a driver and their driving task, such as a drink falling and spilling. Driver inattention however doesn't really deal with any specific event and may be unintentional.
2. An example of auditory distraction could be if the people sitting in the car were shouting or talking loudly therefore distracting the driver.
3. Biomechanical distraction occurs when a driver is doing something physical that is not related to driving, for example, reaching for something and out of the driving position, or holding an item.
4. A huge amount of fine (money) could be charged.
