If a driver passes the grip strength test after carpal tunnel repair, what is the maximum certification period?

When evaluating the maximum certification period for a driver who has passed the grip strength test after undergoing carpal tunnel repair, it is important to consider the regulations set by the Federal Motor Carrier Safety Administration (FMCSA). Following the surgical correction of carpal tunnel syndrome, a driver must be assessed for their ability to perform essential job functions, including grip strength, which is crucial for managing a vehicle safely.

If the driver successfully passes the grip strength test, indicating that they have regained sufficient hand function and strength to operate a commercial vehicle effectively, they can be certified for a maximum of two years. This aligns with the FMCSA guidelines, which allow for a longer certification period when the driver demonstrates the necessary physical capability post-recovery.

In this case, the other options suggest shorter certification periods or outright disqualification, which do not reflect the established guidelines for drivers who have adequately demonstrated their recovery and functional capacity through appropriate testing. Therefore, the correct answer acknowledges the two-year certification opportunity afforded to a driver who meets the criteria after carpal tunnel repair.
