At the moment, you have to click on the Hazard symbol to actually know what the hazard is. And as people alway report vehicles stopped on the hard shoulder as being a hazard, its hard to know what action to take when driving unless you know what the hazard ahead is. It is also dangerous to have to click on the small hazard symbol whilst driving. So why not have different symbols for different hazards? These symbols would be displayed on the map, preventing the need to have to click on the hazard symbol in order to know what the hazard is
