A DOT physical is required for individuals applying for or currently holding a commercial driver’s license and/or hoisting engineer license in the state of Massachusetts. The examination ensures drivers and hoisters are medically qualified to safely operate commercial motor vehicles and hoisting equipment. Because of the responsibility involved in operating large vehicles and equipment, commercial drivers are held to higher physical, mental, and safety standards than passenger vehicle drivers.
Once completed, a DOT certification is valid for up to 24 months. If a medical condition requires monitoring, such as high blood pressure or sleep apnea, certification may be issued for a shorter period.
What to Bring and What to Expect
Vision
If you wear glasses or contact lenses, bring them or wear them to your appointment.
Requirement: Distant visual acuity of at least 20/40 in each eye and both eyes together, with corrective lenses if needed.
Hearing
If you use hearing aids, bring them.
​
Requirement: Ability to hear a forced whisper at five feet in the better ear, with or without a hearing aid. If this standard is not met, formal audiometric testing may be required.
High Blood Pressure
Take medications as prescribed. Avoid caffeine for six hours before your appointment and avoid smoking immediately prior to your visit.
Requirement: Blood pressure must not be at a level likely to interfere with safe vehicle operation.
Medical Conditions Requiring Documentation
If you have a history of cardiovascular disease, including heart attack, angina, congestive heart failure, or other conditions associated with collapse, shortness of breath, or fainting, you may need documentation from your treating provider or cardiologist. This should outline:

Any physical restrictions
Drivers with respiratory conditions such as severe COPD, untreated moderate or severe obstructive sleep apnea, narcolepsy, or certain mental or neurological disorders may also require clearance documentation from their treating provider.
