Why Standard Sat Navs Don’t Work for HGV Drivers
A standard car sat nav will confidently route a 44-tonne articulated lorry under a 3-metre bridge, down a narrow country lane, or through a weight-restricted road. That’s not just inconvenient — it can lead to fines, damage to your vehicle, or serious road incidents.
Professional HGV, lorry and large van drivers need a sat nav that understands their vehicle’s dimensions and weight, and plans routes accordingly. Here’s what to look for.
Essential Features for HGV Sat Navs
1. Vehicle Profile Input
The most important feature. A good truck sat nav lets you enter your vehicle’s height, width, length, weight, and hazardous load status. Routes are then planned to avoid low bridges, weight-restricted roads, narrow lanes, and hazmat-restricted zones.
2. Truck-Specific Maps
Not all maps are equal. Truck-specific maps include data on bridge heights, weight restrictions, turning circle limitations, and road categories (motorway, A-road, B-road, etc.). Consumer maps don’t include this data.
3. Large Screen
When driving an HGV, glancing at a small screen is difficult and unsafe. A 7-inch or larger screen is recommended for professional drivers — large enough to read at a glance without taking your eyes off the road.
4. Lane Guidance and Junction Views
Complex motorway junctions and multi-lane roundabouts are much harder to navigate in a large vehicle. Clear lane guidance and detailed junction views help professional drivers position correctly well in advance.
5. Hours of Service Reminders
Some premium HGV sat navs include EU driving hours reminders and rest stop suggestions — useful for long-haul drivers who need to comply with tachograph regulations.
6. Lifetime Map Updates
For professional drivers, accurate and current maps aren’t optional. Look for a device that includes free lifetime map updates so you’re never routing on outdated road data.
Dedicated HGV Sat Nav vs. Car Sat Nav with Truck Mode
Some devices offer both car and truck modes in one unit. For occasional van drivers or those who split their time between car and commercial vehicles, this can be a practical option. Dedicated HGV units tend to offer more detailed truck-specific routing and better suited interfaces for professional use.
What About Using a Smartphone App?
Apps like Google Maps and Apple Maps don’t support vehicle profiles for HGVs. Apps like CoPilot Truck and Sygic Truck do — but require a mobile signal and ongoing data costs. A dedicated device with pre-loaded maps is generally more reliable for professional use.
