Truck Sat Nav vs Google Maps for HGV UK
Short answer: Google Maps can help with general traffic, places and journey context, but UK HGV drivers should not rely on it as the only route tool for height, weight, width or vehicle-specific restrictions. A dedicated truck sat nav is useful when it lets the driver plan with a vehicle profile and preview risky sections before moving.
Who this guide is for
HGV drivers and buyers deciding whether a dedicated unit is worth it when a phone map is already available.
The question is not whether Google Maps is good. It is good for many car journeys. The question is whether it answers the commercial-vehicle routing problem well enough for the risk you carry.
Where Google Maps is useful
- Finding addresses, business names and nearby services.
- Checking general traffic conditions and estimated journey time.
- Viewing satellite or street-level context before a delivery.
- Sharing a rough location with a customer or depot.
- Using it as a secondary information source, not the route authority.
Where HGV drivers need more
- Vehicle height and low-bridge checks.
- Weight restrictions and weak bridge risk.
- Road width, turning space and local access limits.
- A route preview designed around the vehicle, not just the shortest car route.
- A dedicated screen that does not depend on phone battery, calls or app interruptions.
How to use both without creating confusion
- Use the truck sat nav for vehicle-aware route planning where supported.
- Use phone maps for address context and live traffic awareness.
- If the two disagree, stop and check the route rather than guessing.
- Follow road signs and operator instructions over either screen.
- Keep the driver focused on one primary route during movement.
TruckNav buying fit
- TruckNav is positioned as a dedicated 7-inch in-cab GPS navigator with Bluetooth, AV-IN and European maps.
- That can be a useful upgrade for drivers who want a larger standalone route screen.
- Buyers should still confirm which vehicle-profile fields and map update terms are available before relying on it for regular HGV work.

Official guidance to keep beside the screen
For low bridges and restrictions, use navigation as one part of the safety process. Department for Transport and Network Rail guidance on bridge strikes emphasises checking vehicle height, planning safe routes and responding correctly when a restriction is encountered. GOV.UK vehicle weight guidance is also useful when buyers are unclear about unladen, gross or operating weight language.

Can HGV drivers use Google Maps only?
They can use it for general context, but it is not a replacement for vehicle-aware route checks, signs and operator instructions.
Why buy a dedicated truck sat nav?
The value is a larger dedicated screen, vehicle-profile route planning where supported and fewer phone interruptions during navigation.
Which screen should I follow if they disagree?
Do not guess. Stop safely, check signs and route instructions, then continue only when the route is suitable.
Does a truck sat nav remove driver responsibility?
No. It supports planning, but the driver and operator still manage legal and safety responsibility.
