What are manhole covers?
Manhole covers (sometimes known as inspection covers) are the metal covers that are used to cover over large or small holes created in the road surface to gain access to the equipment underneath. Why are they dangerous? Single track vehicles such as motorcycles have a very small contact patch with the road surface, therefore the availability of grip from the road surface is critical to remaining stable and upright. A consistent (preferably high) level of grip is required to be able to predict the correct method of negotiating a corner. Manhole covers, amongst many other obstacles, usually have low levels of grip (especially when wet) compared to the surrounding carriageway. This problem is often compounded by the placement of covers where a motorcycle would expect to travel. Click here for more information on Manhole Covers.
