The RSPCA is urging drivers to slow down during the winter to avoid collisions with deer.
There has been more than 3,000 collisions in Norfolk and Suffolk involving deer in a two year period.
The RSPCA have released new figures that show the two counties had the second and third highest levels of crashes caused by the woodland animals in England.
This news has prompted the charity to warn motorists using county roads to slow down and look out for deer, particularly during the dawn and dusk hours.
The National Deer-Vehicle Collisions Project by the Deer Initiative found that between 2003 and 2005 there were 1,620 reported incidents in Norfolk and 1,461 in Suffolk, with 119 causing human injury.
Nationally, about 60,000 deer are hit by cars every year, causing about £17m in vehicle damage, injuries in around 700 cases, and killing up to 15 people a year.
