Seat position
All of this might seem fairly basic - but remember, you will need to be able to break down all driving tasks into their basic component parts in order to help your pupils to learn effectively.
When you are satisfied that all the doors are securely closed, adjust the driving seat. You should adjust the seat cushion (that's the bit you sit on) so that all the pedals can be reached.
When the clutch is pressed down fully, your knee should be slightly bent and the seat should support your thigh - it's essential to make sure that your body is fully supported.
The law requires that you are seated in such a way that you can operate all of the controls and have a clear view from the vehicle.
A poor seating position will cause fatigue on longer journeys.
This will in turn affect your concentration and your safety. It is worth experimenting with different positions to find which suits you best. many drivers never realise that they could be more comfortable because they have never thought to try different seat positions.
