It would be better to have an alert area instead of along a segment. Often on a freeway the troopers are running in both directions. and if you are going in the opposite direction of the report you will not get an alert. Police should be reported as a zone not a point.

+10000 for this suggestion.
For everyone saying driving fast is dangerous and wont get home safely, do some research first.

I agree and think the alert distance should be customizable; police alerts could be set to 1/4 mile - 3 miles before police location. And please allow me to turn off hazard warnings and keep police warnings on!

And to all you commenters saying "don't speed", "we want to get home safe too, blah blah blah": don't forget, this app gained most of its popularity for the feature of police reporting. I speed on every highway I travel; without police reports I wouldn't even use the app. So get off your high horses, stay in the right lane and let the non-zombie drivers drive. I save dozens of hours of time spent in the car every year because I speed; just because you can't drive safely at 70mph in a 55, doesn't mean I can't.

Police speed traps often stay for 30 minutes to one hour, but it disappears form waze after 15 or 30 minutes. This is hazardous to other wazers, so please increase the amount of time a warning lasts for to two hours. It can be cancelled earlier given enough (perhaps 5 or 10) not there votes.

The way I see it, the alert is there so that people know there may be an officer on the side of the road, and to keep alert in order to avoid a wreck.

Nobody owes you data on speed traps. Caveat emptor, driver.

janet .. stay out the left lane and worry about your speed thanks ... we all will get home safely

If your worried about getting a speeding ticket, SLOW down. Your not the only one on the road. We all want to get home safely to our families.

it's not 600 feet it's a half mile.

While hwy driving you only have exits spaced miles apart. The traffic jam warning comes to late to find an alternate route or to allow time to change lanes to exit the hwy before you are caught in the traffic.

By the time the Waze warning pops up, you are already stuck in the traffic.

Increase the distance or time warning.

In fact, many times there is no warning, especially if there are multiple reports in succession, only one will be reported, which requires the user to be distracted yet again by touching the symbol in order to give it a thumbs up, etc.

Should also be based on speed - more distance warning at 65mph vs 25mph

I would like this programmable as well.

la distance autour des radars et notamment apres est beaucoup trop longues

This should not be an "enhancement". It should have been a software requirement. I sat in traffic for 2 hours last month because the "accident" warning occurred WAY too late.

Lets try driving using our own eyes first

I agree, increase cop alert range and allow more user customization. For example, be able to turn off vehicle on side of the road alerts. Also, when reporting cops, be able to report cops who already have someone pulled over versus cops running a speed trap.

Saw a recent video where someone ran over a pallet in the road... 1 second after hitting the pallet you can hear waze alert about the road hazard...

Only problem I see is that it will make reporting a lot more complex.

Given I am a user
When I post for instance a police control,
Then I can choose distance from me when posting - for instance - 500 meters behind on current route, 1000 meters behind on current route. The reason being that its often very hard to do a post just at the moment you see the "problem". And placing it on the map is hard when driving.

The distance for all alerts should be individually adjustable from 0-5 miles in .25 mile increments through a settings panel, as well as a customizable repeat notification as the user gets closer to the marked alert. There should also be an option to disable certain alert types entirely. This would greatly enhance the functionality of the app by allowing each Waze user to decide what alerts they want to prioritize, so that important warnings like road debris or police spotted can be properly elevated above less critical warnings such as vehicles stopped on the shoulder.
