Caution on Roadways - Deer on the Move
Posted 05 November 2008
A deer-vehicle collision can happen
at any time in Iowa and it is important for motorists to remain alert
for deer, livestock, other wildlife, and obstacles that can pose a
hazard while driving. With fall well under way, it is a time for
drivers to exercise even more caution as many deer-vehicle collisions
occur in the fall months during the white-tailed deer's breeding season
or "rut."
According to officials with the Iowa Department of Natural Resources,
by early November, bucks become more active with the approaching rut,
increasing their activity and travels in search of does ready to breed.
The animal's attention is on other things and their vigilance when
crossing a road is decreased. In addition to this the bucks are often
crossing roads in areas they are not familiar with or in places they
would usually not cross.
As the rut progresses, and does begin to come into breeding condition,
it is normal for them to be chased for a period of time by one or more
bucks. This creates a situation with multiple, fast-moving, deer
crossing highways that are often oblivious to traffic. Typically, the
month of November has the highest occurrence of deer-vehicle collisions.
In order to help avoid collisions with deer during these times, drivers
should use extra care while driving. Deer may be moving at any time of
the day or night and crossing roads at unexpected places. Drivers
should be constantly scanning the roadside ditches for deer approaching
the highway and understand that their actions will be more
unpredictable than usual. If the driver can spot the deer before it
enters the roadway their chances for avoiding a collision are greatly
increased.
When driving at night, it is recommended that drivers do not use cruise
control as the vehicle remains under full power until the brake or
clutch pedal is depressed and this can mean the difference between
avoiding a collision and having one. Driving slower at night also
provides an extra margin of safety. If you have another vehicle in
front of you, utilize their headlights to help you scan the roadsides
that are beyond the reach of the lights on your vehicle.
Traveling at prudent speeds at night cannot be overemphasized as it is
easy to overdrive your headlights and there are many other highway
obstacles besides deer. The average stopping distance for a vehicle
traveling 60 mph is about 300 feet including reaction time. The
illumination distance of high beam headlights is about the same
distance. However, most drivers do not concentrate on the roadway 300
feet ahead of their vehicle, especially at night and objects smaller
than another vehicle are easily overlooked at these distances. Low beam
headlights are not made for speeds of more than 40 mph. When driving in
areas where forested or brushy habitats are adjacent to highways and
where these habitats intersect highways in depressions or ridgelines,
one should remain alert for deer approaching the roadway. At dawn,
dusk, and at night it is prudent not to drive faster than 50-55 mph in
these specific areas at the very least. If a deer is sighted, switching
headlights to low beam can often "unfreeze" a deer and encourage it to
move off the roadway. Avoid passing in posted deer crossing areas if
possible.
Although the risk of hitting a deer increases in the fall, this risk
can be minimized by remaining alert and driving defensively. Of course,
there are situations were a collision cannot be avoided and it is
important to remember that it is usually safer to hit the animal than
to leave the roadway or to swerve into oncoming traffic.
The number of road-killed deer reported by the Department of
Transportation along with officer reports of salvaged road-kills was
down by 8 percent in 2007 from the previous year. Statewide deer
populations are declining. Regionally, portions of central and west
central Iowa (about 15 counties) still need greater deer harvests to
put those populations into a decline. The Iowa DNR has population goals
and hunting seasons over much of Iowa that are intended to
significantly lower current deer densities. Achievement of these goals
should result in a lower rate of deer-vehicle collisions for Iowa as a
whole. However, even when the population goals are achieved, there will
still be pockets throughout the state with higher densities of deer
where deer hunting is not allowed or where the antlerless harvest on
certain properties is deficient. |
