Maryland Auto Glass Calibration Law 2026: SB 789 Status Update
Updated July 28, 2026: An earlier version of this article incorrectly described Maryland Senate Bill 789 as an enacted auto glass calibration law taking effect in October 2026. The official Maryland General Assembly record does not support that statement. We corrected the article so drivers have accurate information.
What Is the Current Status of Maryland SB 789?
Maryland Senate Bill 789 was introduced during the 2026 legislative session. The official bill record currently lists its title as Motor Vehicle Administration – Advanced Driver Assistance Systems Repairs – Study and its status as In the House – First Reading House Rules and Executive Nominations. The official record does not list SB 789 as enacted law.
You can verify the current title, history, bill text, and status on the Maryland General Assembly SB 789 page. Legislative status can change, so the General Assembly record should be treated as the primary source.
What Did the Proposal Address?
The legislation concerned repairs involving advanced driver assistance systems, commonly called ADAS. As introduced, the proposal addressed repair procedures, documentation, calibration-related work, and a possible role for the Maryland Motor Vehicle Administration. The bill's later title reflects a study rather than the broad set of enacted requirements described in the earlier version of this article.
Because the proposal was amended during the legislative process, drivers and repair businesses should not rely on summaries of the introduced version as if every provision became law. The official status page and final legislative documents are the correct places to confirm what happened.
ADAS Calibration Still Matters Without a New State Law
The bill's status does not change the practical importance of ADAS calibration. Many late-model vehicles use a forward-facing camera mounted near the windshield for lane assistance, automatic emergency braking, traffic-sign recognition, or adaptive cruise control. Removing and installing a windshield can affect the camera's relationship to the road.
Whether calibration is required depends on the vehicle, equipment, repair procedure, diagnostic results, and manufacturer instructions. A qualified shop should identify the glass and camera features before replacement, follow the applicable installation procedure, and explain whether ADAS calibration is part of the job.
Questions Maryland Drivers Can Ask Their Shop
- Does my vehicle have a windshield-mounted camera or other ADAS equipment?
- Do the manufacturer procedures call for calibration after this replacement?
- Is calibration included in the written quote?
- Will I receive documentation showing the result?
- If insurance is involved, what information will the insurer need?
