Scottish Natural Heritage (SNH) is warning motorists that collisions between deer and vehicles increase in certain parts of Scotland at this time of year.
Car accidents involving deer peak, as the clocks turn back.
With the nights starting earlier, the peak commuting time coincides with deer coming out to feed on grass verges near roadsides.
SNH, in conjunction with Transport Scotland and Traffic Scotland, are placing warning messages on electronic variable messaging signs.
From Monday of this week to Monday, 14 November, the signs will warn motorists at key locations on the main trunk roads across West and Northwest Scotland. These messages will be seen on signs on the A9, A87, A82 and the A835.
The latest deer-vehicle collisions research shows there are more than 7000 deer-related accidents every year in Scotland
