SPECS Alerting warns you of SPECS checks and guides you through them. These checks use cameras above the road to record your
car at point A, regardless of your speed. This is repeated at the end of the route at point B. The central system therefore knows
how long it took you to drive from A to B and will automatically calculate your average speed. The DSI takes you through the SPECS
check with various screens. You will always be aware of when a route begins, what the approximate remaining length of the route
is and what your average speed is at that time.
Be careful: many SPECS checks now also measure your average speed over sub-sections of a route. To offer full information
your Stinger will treat each sub-section as an individual SPECS location.
On the Pilot screen, which provides clear visual support, you will see the following screens in the event of a SPECS check:
Notice
Current speed
