Grip Strength Tests

The Federal Motor Carrier Safety Administration does not require any specific test for assessing grip power. Examples of grip strength tests include:

• Dynamometer designed to measure grip strength.
• Sphygmomanometer used as a screening test for grip by having the applicant repeatedly squeeze the inflated cuff while noting the maximum deflection on the gauge.

Remember

The driver must have sufficient grasp and prehension to control an oversize steering wheel, shift gears using a manual transmission, and maneuver a vehicle in crowded areas.
