Distances
A Camera Van alert occurs when you are 500m from its location; a School or Congestion
zone alert occurs at a distance of 125m. These alert distances are fixed. For other types
of hazards, the factory setting for the alert distance is 250m. You can change this
warning distance to 500m or 1000m, if you prefer. You can also choose to double the
warning distance when you are travelling over 50mph using the
