Required versus not required: What’s the difference when there’s a vehicle defect?
There has been a lot of confusion when it comes to non-required components on a commercial motor vehicle. Frequently asked questions include:
- What are the consequences of a defective non-required component?
- What if the defect is tied to a state traffic or vehicle code and not the motor carrier safety regulation (such as an emission-related violation)?
- Will a defect involving a non-required component hit my CSA scores?
Here is some information that will hopefully clear up some of those questions.
Required
The required components and the condition they must be in are found in the Federal Motor Carrier Safety Administration (FMCSA) regulations in Part 393 and the Appendix to Part 396. There is also additional information on how the regulations are applied on the road in the Commercial Vehicle Safety Alliance North American Out-of-Service Criteria (OOSC).
The key concept here is if it is not listed in one of the above, it generally does not exist as far as FMCSA and its scoring system is concerned (the Safety Measurement System in the Compliance, Safety, Accountability program). Therefore, if an officer writes a violation for a defective component that is not covered in the safety regulations, appendix, or OOSC, it will not impact your score in any of FMCSA’s scoring systems. The only exception is a lack of mudflaps when required (also known as splash guards or wheel covers). This is a violation in many states’ vehicle codes, but FMCSA does not have them in their regulations. The violation will be written as a violation of 392.2WC and scored in the Vehicle BASIC in the SMS.
Non-required
If the officer cites a non-regulated defect, such as an active engine malfunction light or a non-functioning auxiliary lamp, the citation will be written under the state’s code, not the motor carrier safety regulations. This is the same violation that would be given to any driver in that state that had that defect on their vehicle. Since it is not a defect listed in the FMCSA regulations, the appendix, or the OOSC, the violation will not appear in the carrier’s FMCSA data.
One issue to be aware of is that the states must have regulations that are compatible with the federal requirements, so most states vehicle and traffic codes are similar. Where there is considerable difference is in emissions. Some states allow or require their officers to enforce the emissions regulations on the road, while other states leave this enforcement to the clean air agency within the state.
Still needs to be repaired
When it comes to addressing defects involving non-required components, the defect will need to be repaired within the time limit in the state’s codes or statutes. Several states also require a follow-up to verify the defect has been corrected, whether it be the submission of a form or an inspection by an officer.
Key to Remember: If the defect involved a non-required component and a warning or citation was written under state law or code, it is still a violation that must be corrected. This is true even though FMCSA does not score it.
