Hi dcofomaha,
the empty checkbox shows up with a width on the web page.
It's strange that i put your code in a demo and the checkbox is wihout wide width:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="checkbox" name="vehicle" value=" "/>
</div>
</form>
</body>
</html>
It looks like:

Thus can you tell me how to make the checkbox with not be so wide?
To avoid this width, you can try to add
style="width:13px". For example,
<input type="checkbox" name="vehicle" value=" " style="width:100px"/>
In this case,

The checkbox does not show up those exports.
Is this checkbox in your reportviewer? And how you export your SSRS?
Best Regard,
Yang Shen
