Understanding DOT OOS (Out-Of-Service) Violation

Commercial vehicle operators must constantly navigate the highly complex world of DOT regulations. When trouble arises, it often comes in the form of an Out-of-Service order (OOS). An OOS order typically grounds a driver or vehicle immediately pending the correction of the cited issues. 

FMCA Filings shares some critical information about the causes of DOT OOS violations. We supply complete compliance and filing solutions for carriers across the United States and provide comprehensive services with features like our FMCSA compliance checklist. 

What Are DOT OOS Violations?

DOT OOS violations are often issued immediately when a commercial motor vehicle or its driver violates safety regulations during a roadside inspection. An OOS order immediately prohibits the vehicle or driver from operating pending correction of the cited problem 

Further, the corrections must be appropriately filed and accepted by the Federal Motor Carrier Safety Administration (FMCSA) before the vehicle or driver can return to service.

Authorized offices issue OOS orders based on many types of infractions — generally categorized into vehicle-related and driver-related violations. 

OOS orders can cite violations from minor mechanical issues to serious safety problems. No matter the cause, any OOS order can lead to significant legal and financial costs for carriers.  

Common Vehicle-Related DOT OOS Violations

Vehicle-related OOS violations usually arise from roadside inspections due to neglect of regular maintenance or failure to perform necessary repairs. Here are some of the most common — and avoidable — citations on vehicle-related DOT OOS orders.

Lighting Violations

One of the more common causes of vehicle-related DOT OOS orders is a lighting violation. Inspectors look for burned-out bulbs, missing reflectors, or non-functioning lights. While some lighting violations are simple to repair and may seem minor, inspectors consider visibility and safety lighting essential and will quickly issue OOS orders for these infractions. 

Brake System Deficiencies

These citations come from worn brake pads, damaged brake lines, or other issues that impair braking performance. Inspectors closely scrutinize brake systems during most inspections.

Tire Issues

Inspectors look carefully for worn tires, improper inflation, or tires with inadequate tread depth. In-station checks can take worn tires out of service before DOT OOS violations occur, but drivers should consistently check tires for proper inflation.  

Faulty Steering Mechanisms

Inspectors test for defects like excessive play in the steering wheel or broken components. Inspectors consider steering malfunctions significant safety concerns.

Suspension Defects

Suspension system issues, including broken springs or damaged shock absorbers, often lead to DOT OOS violations. Inspectors use their judgment to determine whether these problems affect stability and handling to the extent they are unsafe.

Common Driver-Related OOS Violations

Some driver-related DOT OOS violations result from long-standing compliance issues, and others result from specific illegal behaviors that employers can only take a preventative approach toward. 

A driver-related DOT OOS order takes the cited driver off the road immediately. It can have a lasting impact on their commercial driver's license in some cases. 

These are some of the most commonly cited violations leading to OOS orders: 

• Driver qualification issues. Drivers without a valid commercial driver's license (CDL) or necessary endorsements will receive an immediate OOS order. These violations include operating a vehicle without the correct CDL class or failing to carry required medical certificates.
• Hours of service (HOS) violations. Drivers exceeding the maximum allowed driving hours or failing to take required breaks are subject to immediate OOS orders.
• Drug and alcohol violations. Drivers operating under the influence or who fail mandatory drug tests receive immediate OOS orders and typically face significant legal issues before the restoration of driving privileges.
• Moving violations. Officers can issue drivers DOT OOS violations for speeding violations, seat belt violations, and sign violations such as failure to obey traffic control devices like red lights and stop signs.

Why DOT OOS Violations Occur

DOT OOS violations typically occur due to lapses in maintenance, inadequate record-keeping, or insufficient driver training. 

Of course, failing to prioritize regular vehicle inspections and maintenance creates an environment where OOS violations are much more likely. 

More robust human resources management could prevent many driver-related violations. Careful attention to driver qualifications, adequate training on regulatory compliance, and proper oversight are the best preventative cures for those problems.
