Class DangerZoneWarning

java.lang.Object
com.here.sdk.navigation.DangerZoneWarning
public final class DangerZoneWarning extends Object

Represents danger zones. A danger zone refers to areas where there is an increased risk of traffic incidents. These zones are designated to alert drivers to potential hazards and encourage safer driving behaviors. Legally, certain devices can alert you to being in a danger zone, typically indicating the presence of a speed camera. In line with applicable law and industry standard, these alerts are usually provided along a road within a range of 4 km on a motorway, 2 km outside built-up areas, and 300 m in built-up areas​​. The HERE SDK warns when approaching the danger zone, as well as when leaving such a zone. A danger zone may or may not have one or more speed cameras in it. The exact location of such speed cameras is not provided. Note that danger zones are only available in selected countries, such as France.
