I remember one day standing in the field behind my house in NH one day. I had my dress clothes on, light brown cacky's with a blue shirt on. I spent 45 min's watching 9 deer walk through the field from end to end and they never noticed me. I learned a valuable lesson that day. It didn't matter what I had on to wear. Now If I would had happened to be wearing Camo my mind would have said to me it must have been the Camo. "That's why they didn't see me". But that was not the case.
As I said earlier, I believe that what makes HiViz more visible is its contrast to whatever background it is against. Deer are colorblind, and don't have very acute vision either, so your khaki pants and blue shirt is almost as good as camo, just as long as you aren't moving. They do sense movement very well, and have been known to chase down a motorcycle and smash into it just for fun. DAMHIKT
While I don't have a reference at my fingertips, I know that I've read a study that concluded that the same phenomenon is true for motorcycles, to a lesser extent perhaps since most motorists aren't colorblind. A motorcycle is more visible when there is relative motion between the cyclist and the background. So as an example, a bike riding past a car at an intersection is easier for them to to see than one coming head-on. Having greatly contrasting colors may help in situations where there is no relative motion to the background and the car driver isn't color-blind.
Dave,
Do you have anything (other than anecdotal) to show the effect of "target fixation?" I'd like to see something, as I've never seen any studies done before on this often recited phenomenon.
A little surprised you need this, but anyway, try
this one. Assuming you are referring to motorcycling, not deer hunting
.
I am very aware of what target fixation is. Learned it in motorcycle safety school and in the real world out on the streets. But thanks for the refresher.
Dave
+1 - As it relates to the motorcyclist in the example, the thing being called "target fixation" is a description of a rider "freezing up" due to fear of the consequences, and so not reacting properly. So, I think that we all understand what the term means in that context.
My question about "target fixation" was more in regards to whether a motorist not in any fear or danger would actually "fixate" on a brightly colored object, or flashing brake light, and steer towards, or into it like a moth to a flame.
This is an often referenced "phenomenon", but I'm not sure of its reality. There is none of the underlying fear and anxiety that causes what we call target fixation for the new rider. This may be one of those situations where, if you repeat something often enough it becomes accepted as a fact.
Just because someone happened to have had a flashy light and/or a HiViz jacket and some bone headed or drunken driver ran into you doesn't mean that they were actually
attracted to those things. Just that those measures didn't work as a deterrent in that case.
Just to add a little more spice to this discussion have a look at this from a highly experienced UK trial lawyer who delights in taking on difficult and demanding motorcycle cases.

This is certainly a well reasoned and expressed opinion, but I don't see any evidence other than his anecdotal accounts. It's OK to make up his own mind about the effectiveness of bright colors based on that, but I don't see t being particularly persuasive to others.
One thing that he did mention is that in the UK the police wear HiViz jackets and White helmets. Although that may also be true in some areas, this is not necessarily true in the US. The few motor officers we have in this part of the US ride in shirtsleeves in the summer heat (blue or green uniforms) and wear black leather jackets when it's cooler. I suspect that this is true in the majority of US States and municipalities. So, at least here, there is no ambiguous message being sent to other motorists.
I think it is perfectly reasonable for someone to weigh the available evidence and make a conscious decision
not to wear HiViz. The same way that people in this state can choose not to wear a helmet. I do like it better when the people making those decisions have all of the evidence available to make it from.
BTW If anyone thinks that this topic is too simplistic or INSANE to be worthy of discussion, please feel free to skip over the topic in the future.
