Is It Legal to Use a GPS Speedometer While Driving?

What Counts as "Using" a Speedometer While Driving?

When you are behind the wheel, the definition of "using" a device varies by jurisdiction, but one universal rule exists: holding a phone while driving is illegal in almost all developed nations. Therefore, if you are holding your phone in your hand to look at a GPS speedometer app or website, you are violating distracted driving laws.

However, using a GPS speedometer is completely legal if you comply with hands-free requirements. If your device is securely mounted in a dashboard or windshield holder, it is legally treated the same as an onboard navigation unit or factory dashboard display.

Laws in the US, UK, Australia, and International Jurisdictions

United States: Distracted driving laws vary by state, but the vast majority ban handheld device usage. States like California and New York enforce strict hands-free laws, meaning your GPS speedometer must be mounted, and you cannot touch or program it while the vehicle is in motion.

United Kingdom: UK motoring laws are extremely strict. It is illegal to hold a phone or sat nav for any reason while driving. You must use hands-free equipment such as a windscreen mount. Caught holding a phone to check speed results in a £200 fine and 6 penalty points.

Australia: Australia heavily penalizes driver mobile phone use. The device must be fixed in a commercially manufactured holder that does not obscure your road vision.

Safe and Legal Ways to Use a GPS Speedometer

• Always use a secure, commercially manufactured phone mount.
