Emergency Vehicle Lighting
Idaho law strictly regulates the use of colored lights on vehicles to ensure public safety and prevent confusion with emergency responders.
Police Vehicles
- Blue flashing lights are reserved exclusively for police vehicles.
- These lights must be top-mounted and visible from 1,000 feet in normal weather conditions.
Fire and EMS Vehicles
- Red flashing lights are designated for fire trucks, ambulances, and other emergency medical services.
- These lights must be visible from the front of the vehicle.
Tow Trucks and Utility Vehicles
- Amber flashing lights are permitted for tow trucks, construction, and utility vehicles to signal caution to other drivers.
- These lights should be used only when the vehicle poses a traffic hazard.
Underglow and Aftermarket Lighting
While Idaho law does not explicitly prohibit underglow lighting, certain restrictions apply to ensure safety and compliance.
Permissible Colors
- White or amber lights are allowed on the front and sides of the vehicle.
- Red lights are permitted on the rear.
- Blue lights are strictly prohibited on non-emergency vehicles.
Prohibited Features
- Flashing lights of any color are not allowed on civilian vehicles, except for turn signals and hazard indicators.
- Red lights visible from the front are illegal, as they are reserved for emergency vehicles.
Installation Guidelines
- Underglow lights should be installed beneath the vehicle's chassis and must not extend beyond the vehicle's dimensions.
- Lights should not be overly bright or cause glare that could distract other drivers.
Enforcement and Penalties
Violating Idaho's vehicle lighting laws can result in fines and citations. Law enforcement officers have discretion in enforcing these laws, and interpretations may vary.
