The stud diameter must not exceed three-eighths of an inch, not protrude more that three thirty-seconds of an inch from the surface, and not have a contact area in excess of three-fourths of one percent of the nominal contact area of the tires.
Tire chains
Tire chains and/or snow tires are required on a vehicle traveling on a street or highway designated as a snow emergency route when a snow emergency has been declared by the state or municipality of jurisdiction.
Warning devices
Trucks with a maximum gross weight over 10,000 lbs., every omnibus with a seating capacity of more than 10 passengers, and all tractor and trailer combinations, operated upon a public highway must carry emergency lighting equipment ready at all times for immediate use.

All red emergency reflectors must be of a size and type approved by the commissioner of motor vehicles.
