TN HB 1315 Eases Interlock Calibration Rules for Drivers

Overview

Tennessee lawmakers have introduced House Bill 1315 to reduce administrative traps in the state's ignition interlock program. Sponsored by Majority Leader William Lamberth along with a bipartisan coalition of co-sponsors, the legislation alters Tennessee Code Annotated Sections 55-10-417 and 55-10-425. The bill creates a mandatory two-week window for required device servicing and grants judges the power to restore driving privileges when a driver's only mistake was a missed maintenance date.

Key Provisions

• Service window requirement: Interlock providers must permit drivers to appear for calibration, monitoring, or device inspection at any point within a two-week timeframe.

• Judicial reinstatement power: Courts gain the legal authority to order driver license reinstatement if the person has no other active suspensions or revocations and the only noncompliance was related to calibration, monitoring, or inspection appointments.

• Program rule modifications: The bill updates statutory guidelines governing the mandatory ignition interlock usage period, reducing situations where administrative delays prolong restricted driving orders.

Impact on Drivers

Strict scheduling requirements often punish drivers who are otherwise fully compliant. Under the current framework, missing a rigid inspection date can lead to an automatic extension of the interlock order or an abrupt driver license suspension. Drivers living in rural counties face particularly difficult commutes to certified service shops.

HB 1315 directly addresses that vulnerability. The bill does not shield drivers who operate vehicles after consuming alcohol or attempt to bypass the equipment. Instead, it prevents service provider scheduling limits from disrupting an individual's path to license recovery. Judges will have clear authority to excuse missed appointments and reinstate licenses when no public safety threat exists.

Current Law vs Proposed Changes

• Current: Certified interlock providers enforce rigid appointment intervals, and missing an inspection window can immediately jeopardize driving privileges without explicit court remedies.

• Proposed: Service providers must offer a flexible two-week period for all calibration visits, and courts can restore suspended licenses if a missed appointment is the driver's sole violation.

What This Means For You

Do not change your current service schedule while this bill moves through the legislative process. Keep attending every scheduled calibration on time until new provisions take legal effect. Save every receipt and calibration report provided by your service vendor.

If you currently face a license hold exclusively because of a scheduling mishap with your provider, track the progress of HB 1315. Once enacted, the law will give your attorney a direct statutory mechanism to petition the court for license restoration.
