With the number of fallow deer in the UK at some of the highest levels recorded, we are reminding all road users to take extra care this autumn.
At this time of year the male fallow deer is unpredictable and can travel several miles a day in search of a mate, crossing roads in the process. The most common times for the male deer to roam are at dawn and dusk, which in late September and October coincides with the morning and evening rush-hours. Drivers and motor cyclists are particularly vulnerable to deer strikes, while cyclists should also be vigilant and take special care.
The deer population in Hertfordshire, which mainly consists of fallow deer and muntjac deer, is widespread across the county with particular concentrations in pockets of woodland countryside. Although deer are present in residential areas, it is where major roads pass near wooded areas with traffic moving at high speeds, that there is a particular risk of collisions with crossing animals.
Cllr Stephen Giles-Medhurst, Executive Member for Highways at Hertfordshire County Council said: “We would urge drivers and motor cyclists in particular, to be cautious and drive a little slower at this time of the year, especially on rural and semi-rural roads. We have taken steps to erect deer fences in locations which are known migration crossing points, especially on major new roads, but we are unable to protect every road.
“If you do hit a deer, please report the collision to the police on 101.”
Basic safety tips to help motorists and motor cyclists avoid collisions with deer include:
