I dont know how Gregs typ file looks like. It depends how you have configured your type of highway, either a bitmap or vector image.

Bitmap (arrow) on top of a vector image will not work in most cases, unless that bitmap is one of the major line types as in the following example:

Bitmap:

[_line]
Type=0x02
UseOrientation=N
Xpm="32 3 2  1"
"! c #0030FF"
"  c none"
" !!!!!!!!        !!!!!!!!       "
" !!!!!!!!        !!!!!!!!       "
" !!!!!!!!        !!!!!!!!       "
;12345678901234567890123456789012
String1=0x04,cycle route
String2=0x03,fietsroute
String3=0x02,Radroute
ExtendedLabels=Y
FontStyle=SmallFont
CustomColor=No
[end]

Vector:

[_line]
Type=0x03
UseOrientation=N
LineWidth=5
BorderWidth=1
Xpm="0 0 2 0"
"1 c #B4B4B4"
"2 c #525252"
String1=0x04,principal highway
String2=0x03,N-weg
String3=0x02,Hauptverbindungsstraße
ExtendedLabels=Y
FontStyle=SmallFont
CustomColor=No
[end]
