Hi rbarrera, 
thanks for your contributions to OSM!

You have added a few roads as "Motocross racetracks" but it should be another type of road.

Some of them are also close to a main road, but not connected to it (https://www.openstreetmap.org/way/1333219827 for example). Could you please have a look at this and make adjustments? 

Thanks again and happy mapping,
Paul
