I am wanting to add a cement patio on to my house and in order to build a $6000 patio, I have to pay a $5000 road bond to the village does that make sense
Bonds are not insurance. What they are asking for is that you provide a bond to promise to pay up to $5000.00 if the cement truck damages the roads it is travelling on. You go to a bonding company (sometimes your insurance company will provide the bond), pay them a fee for providing the bond and have the work done. If the truck damages a road, the bonding company will pay out up to $5000.00 for the damage, then you will have to reimburse the bonding company for it's outlay. Bonds are NOT insurance.
Is this 'bond' a form of insurance? It sounds as if the roads in your area are less than adequate to support heavy trucks and the village is trying to protect themselves from the expense of repairing the road. You don't say where in the world you are so this may loose something in the translation.
This is up to the township you live in. Cement trucks travel township roads that are classified for weight limits. If the cement truck travels roads exceeding these limits, road damage can happen and then the township/county is stuck with the repair bills. This is of more concern if they travel the roads before the wight restrictions are lifted. The townships restrict road travel to heavy trucks at certain times because of roads thawing out and generally impose no traffic for heavy trucks during certain weeks in late winter and early spring. Thus, they can grant a permit to travel but with conditions applied, like a bond.
