Final answer:
The correct answer is option A. Inspectors will place a vehicle out of service if they determine it to be unsafe or in violation of safety regulations.
Step-by-step explanation:
During the roadside inspection process, inspectors have the authority to remove a vehicle from operation when they find critical safety violations. This is part of the enforcement efforts to ensure the safety of both the driver and others on the road. It’s important to correct any identified problems, but this does not mean that you cannot do so on the spot. If feasible, you can make minor repairs immediately or arrange for them to be done promptly.
The statement about electronic logs is slightly incorrect, as the inspectors will need to check that the driver has the logs for the required period, but the device does not need to be mounted under the hood; it should be in a position where the driver can see it while operating the vehicle. The missing warning triangle is a common violation but not necessarily the most common, as inspection violations can vary widely.
