Federal regulations

Rhode Island has adopted Part 393 of the Federal Regulations.

Applicability

Part 393 applies to any self-propelled or towed motor vehicle used on a highway in intrastate and interstate commerce when the vehicle has a gross vehicle weight rating, gross combination weight rating, gross vehicle weight, or gross combination weight of 10,001 pounds or more, or is of any size transporting a placardable amount of hazardous materials.

First aid kit

No requirements for trucks.

Mudflaps

All trucks, full trailers, or semitrailers with a registered gross weight over three tons must be equipped with suitable metal protectors or substantial flexible flaps behind the rearmost wheels. If the rear wheels are not covered at the top and rear by the fender, body or other parts of the vehicle, the rear wheels must be covered at the top and rear by protective means of a standard type or design that reduces the amount of dirt, water, or other materials thrown onto the windshields of following vehicles. The requirements listed above do not need to be followed if the vehicle is designed and constructed so the fenders, body construction, or other means of enclosure accomplishes the requirements listed above.

Studded tires

No tire may have blocks, flanges, cleats, pointed spikes, or other protuberances of any material other than rubber which projects beyond the tread of the traction surface.

Exception — Vehicles may be equipped with tires with flat-headed studs projecting one-sixteenth inch or less beyond the tread of the traction surface from November 15 to April 1 of each year.

Tire chains

Tire chains of reasonable size may be used on any vehicle when required for safety because of ice, snow, or other conditions tending to cause a vehicle to skid.
