Some satnavs are marketed specifically for drivers of articulated lorries. They warn of low bridges and avoid routes along narrow, twisted roads. However they tend to cost a great deal more than satnavs for car drivers, so many lorry drivers (or their employers) just buy 'ordinary' satnavs, resulting in lorry drivers following routes which are suitable for cars but not for trucks.
On one of the approaches to the town I live in, there's a 'Do not follow satnav' sign for drivers of high vehicles, telling them that they need to turn right ahead (instead of continuing straight on). At the junction where they need to turn, there are two more 'Do not follow satnav' signs on the straight-ahead route, with one on each side of the road:

Those signs are there to back up the normal 'low bridge ahead' signs, which drivers will have already have passed at that point. However that doesn't seem to stop lorries (and big vans) carrying straight on. The bridge got hit 43 times over a 5-year period

but that doesn't count the vans that get stuck under it nearly every day (without Network Rail ever getting to know about it, as the vans are freed by their drivers letting the tyres down), the vans that havee their roof-mounted amber lights ripped off almost every day and the countless lorry drivers who arrive at the bridge and then have to find a way to turn or back up:

Why, I wonder, are the words 'Do not follow sat nav' so difficult for drivers to comprehend?
