There are strict rules around when, where, and how you can use a sat nav while on the road
Improper sat nav usage while driving can result in six penalty points and a £200 fine, potentially leading to license loss for new drivers. Using a hand-held sat nav while driving is illegal, as is obstructing your view of the road with its placement. Exceptions include hands-free devices, voice commands, Bluetooth headsets, and dashboard/windscreen mounts, provided they don't obstruct the driver's view. Obstructing view of the road can lead to harsher penalties.
