A train-like whistle will sound on approaching a level crossing, with a large X marking the intersection
The UK's Highway Code advises the use of care when approaching a level crossing and to only drive onto a crossing if the exit is clear on the other side. After all, finding yourself blocked on the track when a train is coming is probably not a great position to be in (unless you can depend on Hancock to stop the train before it hits). While such things may seem like common sense, that doesn't appear to prevent drivers from taking stupid risks. Now Network Rail and Garmin have teamed up to create a special sat nav app which will sound a train-like whistle when a driver approaches a level crossing.
