http://wiki.openstreetmap.org/wiki/Overpass_API/XAPI_Compatibility_Layer Check the link above ... it even has an example for maxspeed and bbox. Change way to * if you also want nodes and relations. Btw: this page is horrible to use on a mobile device!! Thank you. This is helpful for me.

Please tell us in detail WHAT does not work!
Do you think that a mechanic can help you if you tell him just: "my car does not drive" ??
Have you tried already http://wiki.openstreetmap.org/wiki/Overpass_Turbo ? Read about all its features in the OSM wiki and built-in help pages.
I'm using this link to get maxspeed limit of road but is gives error like The data is made available under ODbL.
Error: line 4: static error: The value of attribute "n" of the element "bbox-query" must always be greater or equal than the value of attribute "s".
Error: line 10: static error: The value of attribute "n" of the element "bbox-query" must always be greater or equal than the value of attribute "s".
Error: line 17: static error: The value of attribute "n" of the element "bbox-query" must always be greater or equal than the value of attribute "s".
Your bounding box is wrong. The numbers must be left,bottom,right,top.
The correct URL would be
http://www.overpass-api.de/api/xapi?*[bbox=42.378275,-71.089382,42.378475,-71.089182][maxspeed=*](second and forth number switched) but it doesn't return any elements because the bounding box you chose doesn't contain elements with a maxspeed tag. In fact, the bbox is somewhere in Antarctica. Did you mix lat and lon, too? In that case try this URL instead which returns data from Boston:http://www.overpass-api.de/api/xapi?*[bbox=-71.089382,42.378275,-71.089182,42.378475][maxspeed=*]Ohhh. This issue not allow me to go forward. http://www.overpass-api.de/api/xapi?[bbox=-77.015412,38.889732,-77.015212,38.889932][maxspeed=] why this not return any maxspeed?
Because your version is missing two "*" characters when compared to scai's version? Or is that just a "copy and paste issue" and you're actually worried that no matching data is being returned?
Actually its not working even if we placed "*" character. And not return any maxspeed.
Your bounding box (which is different to the one in scai's example above) is a tiny area:
http://owl.apis.dev.openstreetmap.org/?box=yes&bbox=-77.015412%2C38.889932%2C-77.015212%2C38.889732#map=19/38.88982/-77.01594&layers=N
The ways in it have no maxspeed tags:
http://www.openstreetmap.org/way/6055099
http://www.openstreetmap.org/way/6062971
EDIT: Clarified that the bbox used differs from the suggestion in the previous comment (just to make it absolutely clear!).
@Omkar The second URL in my previous comment returns two ways with maxspeed tags (http://www.openstreetmap.org/way/9429794 and http://www.openstreetmap.org/way/257681343 ).
