If cabbies have to have CDLs, then doesn't that mean they also have a medical requirement before they can be issued a full CDL? I know a friend of mine still has his CDL but with restrictions since he never renewed the medical part of the license. Maybe I'm confused.
No CDL required. Astounding.
To drive a truck, you have to have a valid medical certificate, renewable every two years. They will change you back to class D if you don't have the medical cert.
And if you have hazardous materials endorsement, another test is required every 4 years. Along with TSA background anal probing. And fingerprints all around. And the test place takes your fingerprints to verify/compare to the TSA prints on file at time of test. And proof of place of birth (birth certificate or passport) is required at test time.
