The only marks on my insurance schedule are through "deer hits", 've hit three in the last five years. They are a real hazard in this part of Scotland....a fatality involving a young girl of 18 just last week, hit the deer and swerved out into the path of oncoming traffic.
They have regular crossing points, so if one knows the road you at least have a chance to cut down speed.

The council here have started cutting back the scrub and undergrowth on the roadsides so that at night you can see the eyes of the deer sparkling in your headlights before they run across.
