What is the standard duration of a DOT card validity?

The standard duration of a DOT medical card validity is typically one year. This requirement is established to ensure that commercial drivers maintain a current medical evaluation every 12 months, which is crucial for ensuring their fitness to operate commercial vehicles. This annual renewal process helps to monitor drivers' health conditions that could potentially impact their ability to drive safely.

While some medical conditions may require more frequent evaluations, or certain exceptions might apply, the predominant standard is indeed one year. This policy is designed to promote safety on the roads by ensuring that drivers do not operate commercial vehicles with untreated medical issues that could pose risks to themselves and others.
