Potholes
Potholes can occur due to a couple of reasons:
- Inferior temporary road fixes, that sink or crack shortly after they are done.
- Wear and tear due to long-lasting traffic on the road causes breaks on the surface.
Sewer Grates Manhole covers
Sewer grates can present a serious danger to cyclists. If sewer grate bars go in the same direction as traffic, bike tires can easily become stuck between them.
Manhole covers
Manhole covers can become significantly lower than the grade of the road causing cyclists to quickly deviate away and sometimes wind up too close to traffic.
Railroad Tracks
Seldom used or even abandoned railroad tracks often times present hidden dangers to cyclists. They are hazardous when the tracks run on the roadway specifically in the direction of traffic, all the more so when tracks cross the road at a curve. A bicycle wheel can easily be caught in the space between the rail and road, causing the cyclist to crash or be thrown in the direction of a motor vehicle.
