There is another weight that you do need to know.
When I do finally get my show on the road, I will have six (how did I get six, I meant four, silly old fool) axles to worry about, but apart from that, there is one bridge that we normally cross to get to a favourite spot that also has a maximum gross weight restriction of 4500kg and there are others around the country as well. My GCW will be in the order of 6500kg to 7000kg, so although I won't have much issue with most axle weight restriction bridges, Gross weight ones will be an issue in some places. :oops:

OK Neil - thanks for pointing that out. So the previous summary
Now, when you are on the road you know two critical pieces of information:
a. Your maximum axle weight
b. Your maximum % of Class I loading

Now when you come to a weight restricted bridge, it's easy:
- If your maximum axle weight is greater than any weight specified in kg's - Don't cross
- If your % of Class I is greater than the percent specified - Don't cross

can be modified to this (just so it's all in one place):

Now, when you are on the road you know three critical pieces of information:
a. Your maximum axle weight
b. Your gross weight ie axle 1 plus axle 2 (for the simple 2 axle situation)
c. Your maximum % of Class I loading

Now when you come to a weight restricted bridge, it's easy:
- If your maximum axle weight is greater than any weight specified in kg's - Don't cross
- If your gross weight is greater than the specified maximum gross weight - Don't cross
- If your % of Class I is greater than the percent specified - Don't cross

Does that now cover what is needed?
