When a vehicle does not pass a roadside inspection, it can be declared "out of service." This means that the vehicle is not safe to operate on the road until the issues that caused the failure are resolved. The purpose of this measure is to enhance safety for both the driver of the vehicle and the public at large.

Being declared "out of service" means the driver cannot continue driving the vehicle until it has been repaired and passes a subsequent inspection. This regulation is in place to prevent vehicles with serious violations, such as brake failures, lack of required equipment, or other safety-related issues, from posing a danger on the road.

It's important to note that while a driver may face fines or receive a recommendation for repairs, these consequences are secondary to the vehicle being declared unfit for operation. Therefore, the effectiveness of roadside inspections hinges on imposing strict measures like an "out of service" declaration to ensure safety compliance.
