Can you use your mobile as a sat nav? The confusing law explained

Many people prefer to use their mobile phone as a sat nav - but experts warn that drivers could be breaking the law by doing so. Here's what you need to know

With stringent measures now implemented for mobile phone use while driving, questions have arisen about the legality of using a phone as a sat nav. Many motorists opt for smartphone apps like Google Maps instead of traditional sat nav devices, yet not following the rules could land you on the wrong side of the law.

Since December 2003, it's been illegal to operate a handheld mobile phone when driving or when stationary with the engine on, which includes inputting or adjusting navigation settings.

The revamped laws of December 2017 impose six penalty points and a £200 fine for anyone caught using a mobile phone whilst driving. This is a rise from the previous penalty of three points and a £100 fine.

Newly qualified drivers, who pass their test within the last two years, will lose their licences upon accruing six points. The RAC warns: "It is no excuse to say you're simply following the mapping on your hand-held device. The mobile phone law specifically refers to this, stating it is illegal to use a hand-held mobile to follow a map."

As for safely utilising your phone for navigation, the recommendation is clear — if there's any risk of having to handle your phone while on the road, it's best not to use it. However, if you must use your phone, ensure you do so with hands-free set-ups to stay within the confines of the law.

The AA has warned that while it's an offence to be seen using a handheld phone while driving, regardless of whether it affects your driving, the same does not apply for hands-free phones. However, if you're spotted not being in control of your vehicle while using a hands-free phone, you can be prosecuted for that offence.

The penalties for 'not being in proper control' include a £100 fine and 3 points on your licence, or up to a £1,000 fine if the case goes to court. It's crucial to set up your phone for hands-free use before setting off on your journey.

If you need to touch your phone at any point during your trip, ensure you pull over and turn off your engine first. If you're using your phone as a sat nav, it's recommended to get a holder to attach to the windscreen or air vents so you can follow instructions without getting too distracted.

However, make sure it doesn't obstruct your view as this could also land you in trouble - under the Highway Code, drivers are required to keep windscreens clear. The RAC advises: "If you wish to use smartphone navigation or a mapping app, fix the phone to the windscreen or dashboard, so it's in clear view for use while driving, without requiring you to hold it. This is, for example, what many private hire and taxi drivers do."

If you think you won't be able to go the whole journey without touching your phone then turn it off and put it away.

And perhaps dust off the old sat nav just to be safe.
