Driving Missouri

It is unlawful to coast downhill on a highway with the gears in neutral.

Status: Still Enforced / On the Books

The Law Explained

Early drivers used to shift their manual transmissions into neutral while going downhill to save a few pennies on gasoline. However, this practice disconnects the engine braking, leading to overheated brakes and dangerous runaway vehicles. The state explicitly banned this hypermiling technique to prevent catastrophic crashes on steep grades.
