3 key trucking rule changes coming soon
Drivers and motor carriers should face fewer citations starting later this month, once some important rule changes go into effect.
Vehicle-related requirements that have long frustrated fleets and enforcement officials alike are being revised or eliminated as of March 23 and April 20, 2026. While their impact is relatively narrow, carriers should understand what’s changing and how to protect themselves if roadside enforcement isn’t up to speed.
1. Rear-impact guard labels
The Federal Motor Carrier Safety Administration (FMCSA) is removing the requirement that rear-impact guards be permanently labeled. Under current rules, trailers are required to have a label certifying that the rear underride guard met federal manufacturing standards at the time it was built.
Though the label is applied by the manufacturer, motor carriers and drivers were expected to ensure it remained in place, a sometimes-frustrating task stretching over the lifetime of the vehicle.
Why the change? The bumper label requirement has been controversial for years. Enforcement agencies and industry groups repeatedly pointed out that the labels frequently fade, wear off, or are removed during repairs, even though the guard itself remains structurally compliant.
Compounding the problem, most manufacturers will not issue replacement certification labels or “re-certify” guards once they leave the factory. As a result, carriers were often cited for a condition they had no practical way to correct.
Although FMCSA previously issued guidance instructing inspectors not to cite missing or illegible labels, confusion persisted at the roadside. Eliminating the requirement altogether resolves that enforcement disconnect without altering the underlying safety standards for rear-impact guards.
What should carriers do?
- Continue inspecting rear-impact guards for structural integrity, mounting, height, and width as required under 49 CFR 393.86 and the annual inspection standards in Appendix A to Part 396.
- Don’t remove existing labels, but understand that their presence (or absence) will no longer determine compliance.
- Update inspection checklists and training materials to remove label verification as a compliance item.
2. Tractor license-plate lamps
Truck tractors will no longer be required to have a functioning rear license-plate lamp while towing a trailer. The lamp will still be required when the tractor is operating without a trailer, however.
Why the change? When a tractor is coupled to a trailer, the rear license plate and its lamp are typically obscured and serve no practical enforcement or safety purpose. The FMCSA concluded that requiring carriers to maintain a lamp that isn’t visible or relevant during normal operations added unnecessary maintenance costs without a safety benefit.
What should carriers do?
- Review maintenance policies to ensure tractors still have operational license-plate lamps when operated bobtail.
- Ensure drivers and maintenance personnel understand when a functioning license-plate lamp is required.
3. Emergency equipment
Drivers will no longer be required to carry spare fuses starting April 20, and they will no longer have the option to use liquid-burning flares as warning devices after March 23. Reflective triangles and/or solid-fuel flares will still be required, as will fire extinguishers.
The rule change for fuses is significant because over 10,000 drivers were cited in 2025 for failing to have them.
Why the change? The spare‑fuse requirement has remained in the regulations for decades, even as vehicle electrical systems have improved. The FMCSA concluded that:
- Blown fuses rarely occur during normal operation and, when they do, the repair is typically handled by maintenance personnel rather than drivers. Nevertheless, spare fuses are widely available at truck stops.
- Other regulations already prohibit operation of a vehicle when required electrical equipment isn’t functioning properly, regardless of whether spare parts are carried.
Similarly, liquid-burning flares are widely considered obsolete and are rarely used in modern fleet operations. Their continued presence in the regulations caused confusion.
What should carriers do?
- Verify that emergency-equipment kits contain at least three compliant reflective triangles or six flares, as appropriate.
- Update driver inspection checklists to remove spare fuses as required items and liquid-burning flares as an option. Motor carriers are free to continue having their drivers carry spare fuses, however.
- Remind drivers that vehicles may not be operated if required electrical systems are inoperative, regardless of whether a spare fuse is available.
- As with the changes described above, use DataQs to challenge any spare-fuse violations cited after April 20, unless still required by state law.
What if you’re cited?
Roadside enforcement practices don’t always change overnight. In addition, states that enforce the FMCSA regulations may adopt different effective dates for rule changes. Motor carriers and drivers should be vigilant about reviewing roadside inspection reports and challenging any citations that were issued improperly.
Bearing in mind that state requirements may vary, motor carriers should use the online DataQs system to challenge any erroneous bumper label or license-plate lamp violations cited after March 20, and any spare-fuse violations cited after April 20.
Key to remember: On March 23 and April 20, 2026, three important rule changes go into effect. Be sure your drivers, maintenance personnel, and others know the impact.
