A tractor trailer slams into what was already a crash scene on the side of a Michigan highway. State troopers were on the scene responding to the incident in the left two lanes, when they say the tractor trailer failed to move over for the emergency vehicles and hit them. Miraculously, there were no serious injuries. Police are reminding drivers that it’s the law to move over one lane for emergency vehicles with flashing lights and reduce your speed by 10 miles per hour.
