At the tactical level drivers exercise manoeuvre control, allowing them to negotiate the prevailing circumstances. It involves tasks in relation to route navigation, the interaction with other traffic and adherence to the rules of the road. Examples include actions like overtaking, turning or gap acceptance.
The control level consists of tasks at operational level. These tasks are the basic actions to operate vehicle control functions and keep speed and course. They include steering, changing gear, accelerating, braking, but also actions like switching on the windscreen wipers.
