I agree with "Ice on Road." In the winter in Michigan this is frequent and would be more accurate than just reporting "snow". Perhaps "Slippery" or "Low Traction" would be more generic, if desired.

There should also probably be a stalled-car for Hazard on Road.

I sought out this website to specifically request that ice be added to the hazards. But there are some other great suggestions on here. It's these road hazards that can really cause some trouble. I also do not understand why something that seems to be a no brainer has been under review for a year and a half.

Can't agree more on "flooding." In a coastal, low-lying area, this is crucial.

something like: ice or "ice on the stree" or "slyppery street" (for oil, mud or ice for example).

Like the recommendation for "Weather" Hazard. Add the option to include more prominent things like "Tornado", "Blizzard", "Flooding" and so on.

I think you need to create an alert for ice on road for freezing times.

++1 on ice or black-ice on roadway after this past week in Dallas area. I kept trying to find it in Hazards & Weather - not there. Very surprised. I would have LOVED to know when I was coming up on an icy patch.

Add Ice on Road to Hazards

These all seem rather easy to add in the existing report options and shouldn't be a difficulty for the Waze team... I'm a bit surprised that this is still "Under review" since August 2012...

Traction Report> Flooded, Ice, Wind, Visibility

I dont know why WAZE cant pickup the direction automatically (if not then manual can still be available) in which i travel to report a road issue. For the last kilometer I have been tracked (on long roads) going North. Then if a accident, then perhaps it could list Heading North (N) South(S) or NE etc. or could that be a problem.

Hazard -> On Road -> Pot Hole (good idea thats been mentioned)

Traffic Lights out> Manned by Traffic officer to assist flow or not.
Traffic Lights Out> Manned /Unmanned

Report> Pave> Gravel Road (for rural and 3rd world countries)
Map Issue> Traffic Alterations> Speed Bumps
Will have to put a low, medium, high pitch discription to indicate the severity of the speed bump/hump.

I write from South Africa and we have acknowledge areas by office road side to indicate high traffic accident area. Could you either:
a) look at gps stats and reporting on a specific proneness to accidents. maybe even overlay weather map to determine conditions and trends relating to various conditions.
b) formal law indicators of such areas
c) and having very long and straight roads in South Africa certain roads are marked with tyre noise grooves to assure your awake over long distance. Perhaps mark long roads with Caution Fatigue signs.

There are a million things one can suggest but lets see if as basic as possible we can make WAZE effective as possible.

A big cause of traffic jams is faulty traffic lights. Please consider adding a report on this, as requested in http://waze.uservoice.com/forums/59223-client-how-can-we-improve-waze-on-your-phone-/suggestions/2720349-create-a-report-category-for-faulty-traffic-light
This has 65 votes + 55 on other topics asking for the same

Emergency parking would be great

Hazard -> Weather ->Wind driving a Artic (lorry) wind is the biggest hazard, as if is suddenly there then not

Add: Hazard>On road>Pedestrian
Add: Hazard>On road>Hitch-Hiker

There also doesn't seem to be the option for reporting construction in the shoulder. This happens a lot and should be added.

Just a quick note: it is not a bad idea to create Slippery road instead of ice or oil on road hazard.

As slippery road can be applied to much more hazards!

Ice on road and water on road reports are critical and would increase adoption in the US mid-west where its lacking. If only one option could be provided and I had to pick - I would pick ice!
