TN SB1927

Requires "speeding offenders" (drivers with license suspensions/revocations due to speed-related violations like reckless driving, drag racing, or accumulating excessive points from speeding) to install intelligent speed assistance (ISA) devices on their vehicles for a minimum 365 consecutive days or the length of their suspension, whichever is longer.

Defines "excessive speeding" as 10+ mph over the limit in zones of 40 mph or less, or 20+ mph over the limit in zones above 40 mph.

ISA devices use location-based technology to actively limit a vehicle's speed to posted limits; devices must be tamper-resistant and capable of reporting circumvention attempts.

Offenders bear costs of leasing, installing, and maintaining the device (with indigency assistance available); providers charge a $12.50 annual administrative fee that funds department oversight.

Noncompliance—including tampering, operating a vehicle without the device, or missing required inspections—results in a 120-day extension of the ISA requirement; the act takes effect January 1, 2027, with annual legislative reporting beginning February 2028.
