Millions of UK drivers rely on sat nav systems—whether built into their cars, separate GPS devices, or simply smartphone apps like Google Maps and Waze. However, what many drivers don’t realize is that using a sat nav incorrectly could land you with a fine of up to £1,000 and six penalty points on your licence.
Motoring law expert Stephen Oldham recently clarified the rules, and the consequences are more serious than many drivers think. Here’s everything you need to know to stay safe and avoid costly fines.
📌 Why Sat Navs Are Risky for Drivers
- Around 41.7 million licensed vehicles are on UK roads (2024 data).
- The majority of drivers use sat navs daily.
- While convenient, improper use could lead to penalties, points, or even a driving ban.
⚖️ What the Law Says About Sat Nav Use
According to UK law, it is illegal to hold and use any device that can send or receive data while driving.
This includes:
- Mobile phones 📱
- Sat nav devices 🛰️
- Tablets 💻
- Any smart device capable of communication
Even if your device is in airplane mode or offline, the rule still applies.
✅ Allowed: Using a sat nav when securely mounted and operated hands-free.
❌ Not Allowed: Holding your phone in your hand while driving—even at traffic lights.
🛑 Scenarios Where You Could Be Fined
- Holding a phone while following Google Maps or Waze
- Adjusting routes manually while in motion
- Checking directions while stopped in traffic or at lights
- Supervising a learner driver and using a device
- Driving a car that auto-stops the engine (start-stop feature) and using your phone
✅ Legal Exceptions
You can legally use your phone/device only if:
- You are safely parked with the engine off
- You need to make a 999 or 112 emergency call when it’s unsafe to stop
- You’re making a contactless payment at a drive-through while stationary
- You’re using the phone to park the vehicle remotely
📋 Penalties for Breaking Sat Nav Rules
| Offence | Penalty | Maximum Fine |
|---|---|---|
| Holding/using phone while driving | 6 penalty points + £200 fine | £1,000 (£2,500 for lorry/bus drivers) |
| Driving without due care & attention | 3–9 penalty points + fine | Unlimited (court decides) |
| Not in proper control of vehicle | 3 penalty points + fine | £1,000 max |
🚦 Expert Advice for Safe Sat Nav Use
Motoring solicitor Stephen Oldham recommends:
- Set your route before driving – don’t adjust while moving
- Use a proper mount – dashboard or windscreen holders are best
- Rely on voice commands – minimize distractions
- Stay focused on the road – sat nav is just an aid, not a replacement for safe driving
🔑 Key Takeaways
- Holding your phone = illegal = £200 fine & 6 points minimum
- Worst-case scenario: £1,000 fine and driving ban
- Hands-free, mounted sat navs are legal ✅
- Always prioritize road attention over screen attention
📝 Conclusion
Sat navs are a great tool for modern driving, but using them incorrectly can turn convenience into a costly mistake. To avoid fines, penalty points, and even a potential driving ban, always ensure your device is hands-free, securely mounted, and set up before you start your journey.
Remember: your sat nav is there to help you, not distract you.
