Google Maps remains the most widely used navigation tool in the world, including by truck drivers. The problem: this application was not designed for multi-ton vehicles subject to height, weight, or transit restrictions. Calculating a truck route with Google Maps therefore requires compensating for its shortcomings with adjustments, checks, and sometimes a complementary tool.
What concrete gaps separate standard navigation from truck-adapted navigation, and how can they be reduced without multiplying software subscriptions?

Truck restrictions and map updates: what apps really integrate
Most articles contrast Google Maps (consumer-grade) with professional GPS (truck-specific) without detailing a crucial technical point: the frequency of updates for local regulatory restrictions. Municipal orders on weight limits, height restrictions under bridges, nighttime transit bans in certain urban areas: this data changes regularly.
Since 2023-2024, several GPS and professional applications automatically integrate these restrictions via weekly or monthly map updates. Google Maps, on the other hand, does not offer a dedicated layer for truck constraints on its desktop version. On mobile, a setting allows declaring a vehicle type, but the coverage of local restrictions remains partial and depends on the data available by country.

Before plotting a route, it is therefore wise to calculate a truck route with Google Maps by cross-referencing it with an up-to-date regulatory source, whether it be a second tool or a manual check of local orders along the planned route.
Google Maps vs truck applications: feature comparison table
The table below summarizes the functional gaps between using Google Maps alone and specialized tools for road transport.
| Feature | Google Maps (mobile) | Truck apps / GPS |
|---|---|---|
| Height, width, weight restrictions | Partial adjustment (vehicle type) | Automatic integration of local orders |
| Cost calculation (fuel, tolls) | Not available for trucks | Estimation based on consumption, fuel type, and tolls |
| Complete offline mode | Downloadable maps, but limited navigation | Offline navigation by country or region |
| Optimized multi-stop route | Up to 9 stops, without automatic order optimization | Order and delivery window optimization |
| Real-time traffic alerts | Yes (very effective) | Variable by tool, often less responsive |
| Update of regulatory restrictions | Irregular, depending on contributors | Weekly or monthly on recent tools |
Google Maps maintains a clear advantage in real-time traffic alerts. However, it does not calculate the actual cost of a trip for a truck (consumption, fuel type, tolls), whereas tools like Roole Map or TruckFly provide a direct estimate.
Double-checking and offline navigation: the truckers’ field method
Feedback from drivers on specialized forums confirms an increasingly common practice: the systematic double-checking of the route. The principle involves preparing the trip on Google Maps (satellite view, visual identification of narrow areas, estimated travel time), then switching to a truck GPS for active navigation.
This method addresses two concrete problems.
- Google Maps sometimes suggests shortcuts through unsuitable municipal roads or industrial areas for heavy vehicles. The satellite view allows for visually identifying a passage under a bridge, a tight turn, or a road without the possibility of turning around.
- On certain roadways (rural areas, tunnels, narrow valleys), loss of mobile network makes online navigation unusable. Recent specialized applications are developing complete offline modes with downloadable maps by country or region, a point rarely mentioned in traditional guides.
- Cross-referencing the two tools also allows for balancing between the fastest route (displayed by Google Maps) and the most fuel-efficient route (calculated by a tool integrating the vehicle’s actual consumption).
Google Maps settings to check before each departure
On the mobile version, the “Route Options” tab allows avoiding highways, tolls, or ferries. For a truck, disabling the “highways” option can significantly lengthen the trip without real gain. It is better to check “avoid tolls” only if the toll cost exceeds the time savings, keeping in mind that alternative roads often impose size constraints not indicated by Google Maps.
Declaring the vehicle type (available on certain mobile versions) modifies route suggestions but does not guarantee the absence of prohibited passages. This feature depends on the completeness of the mapping data in the area traversed.
Truck trip cost: the angle that Google Maps does not cover
An effective route for a truck is not measured solely in kilometers or minutes. The actual trip cost includes fuel consumption (which varies greatly depending on the load, elevation, and speed), tolls, and mechanical wear related to the road profile.
Google Maps does not display any cost estimates for commercial vehicles. Recent European tools like Roole Map offer automatic trip cost calculations based on vehicle type, taking into account fuel type and declared consumption. For a carrier making several trips per week, the difference between the “fastest” route and the “cheapest” route can represent a significant gap in the monthly fuel budget.
TruckFly, another French application, focuses on locating truck-friendly fuel stations and real-time fuel prices, which usefully complements Google Maps planning without replacing it.
Balancing time and cost according to the type of mission
For a long-distance delivery with a tight time window, time is paramount: Google Maps remains the best tool for estimating arrival time in real-time. For a regional tour with multiple stops and no urgency, optimizing fuel cost becomes the main criterion, and Google Maps alone is not sufficient to decide.
The choice of tool therefore depends on the type of mission, not a general preference. Combining Google Maps for real-time traffic with a specialized application for restrictions and costs remains, to date, the most reliable method for a truck driver who wants to comply with regulations and manage expenses effectively.
