the device is properly secured and will not impede airbag deployment.
you don’t interact with the device in anyway while driving.
you can hear the voice directions as listening is less distracting than looking.
you learn how to quickly pick up the key information you need from the device well in advance of the hazard or the next turning point so you can assess the situation early with your own forward planning skills.
you use your common sense and any other signs that tell you the sat nav is wrong - don’t follow it blindly.
Remember, if you don’t turn when directed your sat nav will recalculate to get you back on route but don’t rush to change direction without careful assessment of the situation.
The common instruction “Do a U-Turn where possible” is not an instruction to be rushed! The examiner will set the sat nav up for you. You cannot use your own sat nav.
