When you travel from A30 towards Farnborough through Fernhill Road, you drive past Woodland Walk to your right and you go down hill - you will than see care home to the left and police van in front of you - literally when you come down speeding from that steeeep hill.
When you travel from Farnborough via Fernhill towards A30/Camberley - you drive past Cooperative and Tandori place on your left and the police van will be visible in straight reach to your right. so make sure you will slow down in front of that little roundabout by the shops / Post Office.
