R.I. Gen. Laws § 31-15-6: Clearance for overtaking.

No vehicle shall be driven to the left side of the center of the roadway in overtaking and passing another vehicle proceeding in the same direction, unless the left side is clearly visible and is free of oncoming traffic for a sufficient distance ahead to permit the overtaking and passing to be completely made without interfering with the safe operation of any vehicle approaching from the opposite direction or any vehicle overtaken. In every event the overtaking vehicle must return to the right-hand side of the roadway before coming within one hundred feet (100′) of any vehicle approaching from the opposite direction. Violations of this section are subject to fines enumerated in § 31-41.1-4.
