It could be verified in other ways. For example official reports based<br>
on statistics. Or newspaper articles on accidents caused by crossing<br>
animals on a certain stretch of road.<br>
<br>

<br>
I agree. In fact there is not much point in tagging even the signed<br>
parts.<br>
<br>
The reason for those signs is that the driver cannot see road ahead or<br>
that it is difficult to judge the sharpness from the perspective of a<br>
car.<br>
But with a map it can be done. A data consumer is in a better position<br>
to decide if turns are hazards. When using a navigation system, I can<br>
look at the screen and judge if the next turn could be a problem.<br>
<br>
I could also tell my navigation software which vehicle I am driving and<br>
it could use that information together with my current position, my<br>
actual speed and the data on the road ahead to decide if I should be<br>
alerted.<br>
<br>
For the same reason there is also no reason to tag signed hazards for:<br>
<br>
Tunnels:<br>

<br>
Steep inclines/declines:<br>

<br>
level crossing without gates:<br>

<br>
bridges that open:<br>

<br>
Quays without guards: <br>
<a href="https://www.retsinformation.dk/image.aspx?id=196668&img=CX316_8_80.png" rel="noreferrer" target="_blank">https://www.retsinformation.dk/image.aspx?id=196668&img=CX316_8_80.png</a><br>
<br>
because all those can be inferred from other tags.<br>
