1. Flashing Light Colors & Authorized Vehicles
Statute: R.I. Gen. Laws § 31‑24‑31
-
Flashing lights are prohibited on private vehicles—unless:
- The vehicle is an authorized emergency vehicle (police, fire, ambulance)
- A school bus
- Snow-removal equipment
- Or used specifically for turn signaling (front = white/amber, rear = red)
- If using flashing lights to indicate turns, they must be: front-mounted (white/amber), rear-mounted (red), and visible at ≥ 500 ft.
Statute: R.I. Gen. Laws § 31‑24‑30
- Red lights in front of a vehicle are forbidden unless it is an authorized emergency vehicle.
Statute: R.I. Gen. Laws § 31‑12‑8
- To be exempt from traffic laws (sirens, running red lights), an emergency vehicle must:
- Sound an audible signal (siren, bell, etc.)
- Display at least one red light to the front, visible ≥ 500 feet—except police vehicles, which may omit the front-facing red light.
2. Volunteer/Emergency‑Service Permits
Statute: R.I. Gen. Laws § 31‑23‑11.1
- Private vehicles (e.g., volunteer firefighters/EMS) may use red flashing lights only with a permit issued by a joint local fire/police chief committee.
- Permit validity is limited to that jurisdiction and only while responding to emergencies.
- These are sometimes called “courtesy lights”; they do not bestow full emergency privileges like sirens or full right-of-way.
3. Traffic Signal Preemption Devices
Authorized emergency and certain public safety vehicles may install devices to trigger traffic signals (to get a green light) if used with red or blue flashing lights.
4. “Move Over” Law and Flashing Lights
Rhode Island’s Move Over law requires drivers to move over or slow down for vehicles displaying red, blue, or amber flashing lights—a category that includes police, fire, EMS, tow trucks, utility and maintenance vehicles.
5. Other Vehicle Lighting: Legality & Restrictions
Permitted (Non-Emergency) Lighting
PER federal/NHTSA and RI law for regular vehicles:
- Front-facing lights: Must be white or amber (e.g., headlights, DRLs, fog lights).
- Rear-facing lights: Red only (e.g., taillights, brake lights, reflectors).
- Side markers/turn signals: Amber at front, red at rear.
Non-flashing amber lamps (roof‑mounted on tow trucks, construction vehicles, etc.) are generally allowed to enhance visibility—but must not mimic the flash pattern or brightness of emergency lights.
Prohibited Lighting
- Front-mounted red flashing lights on non-emergency vehicles (no exceptions).
- Red/blue flashing lights without proper authorization or permit (strictly reserved for emergency use).
- Flashing lights of any prohibited color on private vehicles—unless permitted for volunteer service.
Aftermarket/Decorative Lighting (e.g., underglow, neon, RGB bars)
Rhode Island does not have a specific statute on decorative lighting, but general rules apply:
- Underglow or decorative flashing lights in red, blue, or front-red orientation could be misinterpreted as emergency signals—use at your own risk.
- Use of flashing lights across prohibited color spectrums may lead to citation under general flashing light bans.
