One of the snags of using sat-nav is that it can lead you into unexpected places, made worse if you can’t read English.
So pity this French coach’s driver who turned off the B3263 near Tintagel, Cornwall.
A sole blue rectangular sign saying ‘Unsuitable for heavy vehicles’ didn’t help. To road was closed while the vehicle was recovered after trying to make a U-turn.
Sadly, notes The Whisperer, there is still not a Sat Nav suitable for coaches and buses.
