SEMA seeks federal guidelines that provide a clear roadmap for the range of ride height and vehicle profile modifications that maintain proper ADAS calibration
Washington, D.C.—The Specialty Market Equipment Association (SEMA) and industry advocates visited the nation’s capitol last week to promote sound policy surrounding advanced driver assistance systems (ADAS).
Across 15 meetings, the team called on Congress to take a careful, comprehensive look at how the federal government can shape ADAS policies. SEMA is working to ensure that lawmakers and committee staff understand the critical importance of properly recalibrating ADAS whenever a vehicle is customized or modified.

Aftermarket manufacturers design, sell and service a wide range of products — such as vehicle wraps, lift kits, bike racks, bumpers, winches and side mirrors — that must work seamlessly with the ADAS technologies integrated into today’s vehicles.
To ensure those systems perform properly throughout a vehicle’s lifespan, aftermarket businesses seek federal guidelines that provide a clear roadmap regarding the range of ride height and vehicle profile modifications that maintain proper ADAS calibration.
Additionally, the industry is advocating for the 2026 Surface Transportation Reauthorization Act, otherwise known as the highway bill, to provide federal guidelines to calibrate ADAS and validate that safety systems operate as originally designed to ensure driver and passenger safety.
