First, know their typical behaviors. Deer are most active between dawn and dusk which means that the highest chances of being involved in a deer-related accident occur between 6 p.m. and 9 p.m. Do not swerve in attempt to avoid hitting a deer as it may confuse the deer on where to run or worse, result in an accident with another motorist. If hitting a deer is unavoidable, brake hard but quickly ease off before the point of collision to mitigate the chance of serious injury and damages. To evade the chance of collision entirely, stay in the left lane to avoid the shoulder as deer usually crop up there.
