Hi Bill, Dave
Or a smaller, upright seated motorcycle using - for choice - an open-face 
helmet& visor; like Bill I'll do this on low-target lanes on big estates as 
an initial ride-by and then go back and look at ones whose 'jiz' suggests 
possible issues- either possible pathology/defects, or of a size/spp/target 
where a further look is indicated. I don’t think I'd class a tree as 
inspected unless I'd actually stopped, got off, and looked at it; but use the 
system to eliminate ones where a more detailed inspection is very unlikely to 
show up a hazard.
Ps for a spec, talk to highway officers/depts; their chaps do this all the 
time re road issues.

Hi David 

I’ve only done a couple of these, although they were on private estate roads 
where speed or other traffic wasn’t any kind of issue.

Nevertheless, it’s often easy to spot some significant concerns even driving 
at 70mph on a motorway, so long as the trees are far enough apart that they 
stand out.  

However, if you’re driving through a densely wooded area (eg. Ampfield 
Straight Mile down here, see: 
<> ) I doubt that 5mph would be slow enough to 
reasonably spot what’s going on, and it would make YOU the potential hazard 
to road users!

So I’m not at all sure how you can be prescriptive in writing a protocol.  
But from my experience I'd certainly recommend the advantages of driving a 
convertible :o)

A driver and a spotter.  Both sides of the road driven.  At what speed 
do you reckon a windshield/drive-by should be carried out to pick up 
'Obvious Defects'*?

For example, is driving at around 30mph going to reveal significantly 
less obvious defects than driving at about 10mph?  Or significantly 
more obvious defects than driving somewhere close to 50mph?

If you had to choose a speed limit, what would it be?
