📋 CDL Medical and Physical Requirements

The physical requirements of the trucker’s job depend on the driving type. Moreover, regardless of the type, a driver must be physically capable of running a commercial motor vehicle and to perform the different types of non-driving trucking responsibilities. 

The duties of a commercial vehicle driver may involve handling long periods of driving, potential family and/or social challenges, job-related stress, and irregular sleep schedules. Additionally, a trucker's job may also include the following:

  • Heavy lifting in the loading and unloading process.
  • Getting in and out of the truck numerous times a day.
  • Occasional installation of tire chains
  • Other possible physical activities.

In order to secure your physical and medical requirements, you must have a valid Medical Examiner’s Certificate or a DOT card. You should also need to present a photographic copy of your authentic Certificate to receive a CDL. This is a federally mandated certificate given by the U.S Department of Transportation that serves as the basis that you were able to meet all medical and physical standards for operating a commercial vehicle and the original copy must be in your possession whenever you are driving.

💭 CDL Questions guide - CDL certification study resource

What is the required age for a truck driver?

"What are CDL age requirements?" many young people wonder as they consider earning a CDL instead of a regular four-year college degree. To obtain a commercial driver's license, you must be at least 18 years old in every state. To transport merchandise across state lines, however, federal regulations require drivers to be 21 years old.

What are the CDL vision requirements?

The Snellen Test is the most popular method of determining whether or not someone meets the vision standards for CDL drivers. This is a basic doctor's eye chart or vision chart test that determines if a driver can see as clearly as someone with average vision at the same distance. People with 20/20 vision can detect the same size text from a distance of 20 feet as people with normal vision.

The vision requirements for CDL drivers, on the other hand, go a step farther. Individuals must have 20/40 vision to earn a CDL, which means they can see text from 40 feet away with the same precision as if they were just 20 feet away. If a motorist fails to meet this criterion, they will very certainly need glasses or contact lenses to acquire this Snellen score.

CDL Driver License Requirements Per State

Each state may cover the following requirements:

  • You need to have 20/40 acuity (Snellen) in each eye with or without correction. At least 70 degrees peripheral in horizontal meridian measured in each of the eyes. Eyeglasses or contact lenses are acceptable, but the use of corrective lenses should be remarked on the Medical Examiner’s Certificate.
  • You cannot be a diabetic who needs insulin via needle injection. However, take note that some drivers may be exempted.
  • You must first understand forced whispered voice greater than 5 ft. with or without hearing aid.
  • Drivers should not have any current clinical diagnosis of high blood pressure that will likely interfere with their ability to operate a commercial motor vehicle safely.
  • Other medical conditions like sleep apnoea may also be a disqualification.

Note: The conditions above may also apply to Class A CDL requirements and Class B CDL requirements.
