So today with the small amount of snow that created very slick roads, I respond to a crash on I 96 express lanes at Greenfield. The crash was a one car that hit the median wall and was blocking the right lane. I threw some flares and got back in my patrol car. Cars began to lose control but fortunately none came near me or the car I was blocking. As I watched traffic, I see a semi truck driving towards me in the right lane. By the time he saw me, he began to lose control of the truck. I have my car in gear ready to move it, just in case. The semi ended up jack knifing and blocking all three lanes of travel and caused every car to come to a stop. No more cars spinning out towards me!! This morning before going to work, I asked God to not only protect me but to protect all police officers today. What can I say?? PRAYER WORKS!! Thank You Lord for keeping me (us all) safe!!
