You might notice something different on plow trucks in the Mid-Michigan area: green flashing lights.

The lights are a change for this winter season. Governor Rick Snyder signed a bill into law in the summer of 2016 allowing road commissions statewide and MDOT to add the flashing green lights to plows. The goal is to reduce crashes between cars and plows in a heavy snowstorm.

The lights are to help increase visibility. Experts say the color green is brighter and can be spotted from much further away especially in foggy and winter weather. The lights also alert drivers not to get too close to the plows. Road commissions say drivers had become numb to the traditional amber lights. The green lights have not replaced the classic amber lights but rather both sets are now lighting up plow trucks.

More than 85% of county road commissions statewide have installed the lights on trucks including Ingham County.
